Introduction to the Motor Operator Axis Control Range

Introduction Below is an overview of a motor operator axis control architecture:

Premium

Variable speed controller

Axis control range

Motor

Tachometer

TSX CAY

PL7 Junior/Pro

Encoder l l l

The motor operator axis control range for Premium PLCs is made up of 5 modules:

TSX CAY 21 (2 independent axes with limited run-time only),

TSX CAY 41 (4 independent axes with limited run-time only),

TSX CAY 22 (2 independent and/or master/slave axes with limited and/or infinite run-time), l TSX CAY 42 (4 independent and/or master/slave axes with limited and/or infinite run-time), l TSX CAY 33 (3 independent and/or interpolated axes with limited and/or infinite run-time),

The PL7 software includes as standard the application-specific movement function for programming these axis control modules.

The basic movements are controlled via the machine’s principal sequential command program, but are made and checked by the TSX CAY modules, which ensure the position of the moving part is controlled.

The position of each channel is measured by either an incremental encoder or by an absolute encoder. The analog output is used to control a variable speed controller.

TLX DS 57 PL7xx

TSX Modules

CAY 21 / 41

General introduction

These modules (2 and 4 axes respectively) are used to control the movement of independent axes on machines with limited run-time. They are also used for master

/ slave applications.

Introduction

TSX Modules

CAY 22 / 42

These modules (2 and 4 axes respectively) are used to control the movement of independent axes on machines with infinite run-time (usually rotational axes or similar). This type of application creates a measurement variation area called the

"Modulo". These modules are also used to perform master-slave object tracking applications.

TSX

Module CAY 33

General introduction

This module (3 axes) is used to control the movement of axes, which are linearly interpolated on Cartesian machines with limited run-time. It is used to follow trajectories, either on a plane (2 axes), or in space (3 axes).

Introduction

The following diagram provides an outline of an interpolation of 2 axes:

Vx Xb

The TSX CAY 33 module can be used in the following configurations: l l l

3 interpolated axes,

2 interpolated axes and one independent axis,

3 independent axes (in the event of use without interpolation).

This module does not provide the necessary circular interpolation to process bypass applications.

TLX DS 57 PL7xx

General introduction

Functions Provided by the Axis Control Modules

General The axis control modules provide application inputs and outputs for each of the axes, which are used to implement the different functions.

The following diagram shows the inputs/outputs associated with one channel:

General introduction

Application inputs/outputs l l

For each of the axes, the axis control modules offer:

In inputs: l One input to acquire position measurements: l either via type RS 485 incremental encoder (maximum frequency 500 KHz without multiplication or 1 MHz multiplied by 4). The module provides the l choice of either multiplying by one or by four, or by absolute encoder, for up to 25 bits of data, with serial link and transmission according to SSI protocol (200 KHz clock frequency).

l One input serving as a reference point cam (if an incremental encoder is selected), l l l l

One event input,

One emergency stop input,

One re-calibration on-the-fly input,

One drive fault input.

In outputs: l One 10 V analog output isolated from the logic part of the module. This 13 bit + sign resolution output is used to control a variable speed controller, associated with a continuous current motor, on autosynchronous or asynchronous auto-pilot,

A relay output to enable the variable speed controller,

A static auxiliary output.

Programming a movement

In PL7 language, each independent axis movement is described by a SMOVE movement command function. Movements of interpolated axes are described by an

XMOVE command (linear interpolation of TSX CAY 33 module). From this SMOVE or XMOVE command and from the position of the moving part, module TSX CAY calculates the position/speed setpoint.

Configuration and adjustment parameters

These parameters are used to define the usage characteristics, limits, resolution, control dimensions, etc.

Position control loop

The loop controller is of proportional type with feed forward, so as to reduce following errors.

For each axis, the user can choose between 3 types of acceleration law: rectangular, trapezoid or triangular.

TLX DS 57 PL7xx

General introduction

TSX CAY module functions

The functions offered by the axis control modules are as follows: l Position slave movement of another axis: one or more axes can be controlled l by a master axis. The movements of the slave axis thus follow all the movements of the master axis,

Slave movement of a periodic setpoint: periodically, the position setpoint can l be sent directly by the PLC processor,

Re-calibration on-the-fly: this function (used with an incremental encoder) is used to monitor the position of the moving part and to recalibrate the measurement when the re-calibration input is activated. This function can be used for movements with slip, so that the position measurement is periodically recalibrated.

l l l

Event processing: events detected by the module can be used to activate an event task in the sequential program,

Feed hold: this function is used to momentarily stop a movement in progress

(e.g. to synchronize the axes),

Deferred pause: this function is used to momentarily stop a machine cycle without causing disturbance to it, l l l l

Step by step mode: this mode is used to carry out a sequence of movements stopping after each elementary instruction,

Movement monitoring: this function is used to detect any abnormal process operations (such as a faulty encoder), which do not change the position value even when the moving part moves,

Infinite axis function: (only available on the TSX CAY •2 modules), this function is used to process unlimited-type axes ("conveyor belt" applications). The axis defines a movement, which is always performed in the same direction.

It is also used for two other types of application: l the drift function, l synchronized movement of infinite axes.

Linear interpolation function (only available on the TSX CAY 33 module). This function is used to associate 2 or 3 axes with the application-specific Interpolation function. It is used to access certain functional characteristics of numerical command machines.

Note:On the TSX CAY 33 module, the 3 physical axes (X, Y, Z) use channels 0,

1 and 2. Channel 3 is dedicated to the linear interpolation function.

Introduction

Transfer device

The following example covers all the phases for setting up a TSX CAY axes control application. It complements the set-up methodologies.

A transfer device evacuates the parts during machining output. This device consists of a grab which can move through the air along a plane (X, Y axes) parallel to the ground.

As soon as a part appears on evacuation conveyor A, the grab automatically retrieves it and deposits it on conveyor B or C depending on the type of part. The grab then returns to the waiting position until a new machined part needing to be picked up is detected.

The following figure illustrates this transfer device:

Before creating an application program, the operational context of the physical and software configuration in which it will be executed must be defined: type of

Premium TSX processor, input/output modules used.

Furthermore, when programming axis control modules, the configuration parameters of the axes used must be defined. To do this the PL7 software provides the configuration editor, which enables these operations to be performed with ease.

The configuration editor also gives access to the axis adjustment parameters and to the debugging functions in online operation.

The Application browser is used to access the configuration editor. To do this:

Initial resolution

Introduction

Resolution calculation example

The initial resolution corresponds to an encoder increment. As this is usually not an integer, it is expressed in the form of the following ratio:

RESOL = Distance / No. of points where: l l

Distance = distance covered by the moving part

No. of points = number of encoder points corresponding to the distance covered.

The threshold is 1 to 1,000,000.

The resolution is then deduced from these 2 parameters (Distance and No. of points) in a ratio of 0.5 to 1,000.

Either an incremental encoder of 512 points per turn. The distance covered by 1 encoder turn is 10,000 microm (microm = chosen length unit).

You must enter: l Distance = 10 000, l No. of points = 512

The resolution is then 19.5 microm:

RESOL = 10000 512 =

Note: You can correct this resolution in the adjustment screen. It is therefore called the initial resolution.

In the case of an incremental encoder with multiplication by 4, enter the distance corresponding to RE (See

Encoder Type, p. 79)

You can choose your own measurement units, with the Length field allowing a maximum of 5 characters to be entered. For example, degrees.

You must, however, choose the position unit to be such that the resolution value

(Distance / No. of points) is between 0.5 and 1,000. The speed unit is calculated using the formula:

Speed unit = Position unit * 1000 / min

Note: You cannot choose the speed unit which results from the formula. You can however modify the text. For example,

Either an incremental encoder capable of 500 points per turn. The distance corresponding to 1 turn is 2mm, or 2000 microm. The resolution is expressed by the ratio of 2000 / 500 (thus in microm). The resulting speed unit will be mm/min

Modulo

Introduction The modulo is applicable with an infinite machine when position measurement moves between 0 and modulo.

Measurement progresses as follows:

Measurement

Max. Modulo For the Max Modulo parameter you must enter the modulo value in encoder points.

The equivalent in user units is displayed automatically in the following field.

Max. Modulo thus defines the hi limit authorized for the adjustable Modulo parameter. The values which can be entered for Modulo and the associated parameters depend on the encoder type used.

For an absolute encoder

The modulo is always a power of 2 because it is defined by the number of data bits from the SSI Frame encoder. Thus, rather than entering the number of modulo bits, you must enter the corresponding power of 2.

For example, for a max modulo of 4096, you must enter the value 12 (because

4096 = 2

The limit values of Max. Modulo are also limited according to the value of the chosen resolution:

Maximum speed

Introduction

VMAX Value

The maximum speed VMAX must be such that the resultant frequency satisfies the following condition:

1.8 kHz < FMAX < 900 kHz with FMAX = VMAX x m / RESOL m = 2 with a x1 incremental encoder or an absolute encoder, m = 4 with a x4 incremental encoder.

The condition on the maximum frequency is translated onto the VMAX value by the following relation:

108 x RESOL / m < VMAX < 54000 x RESOL / m restricted to the following limits:

270 < VMAX < 270000

Note: VMAX and RESOL are expressed in the units defined in the configuration screen, either RESOL in microm and VMAX in mm/min, or RESOL in mm and

VMAX in m/min, etc.

Authorized speed

Whatever the speed programmed in the instructions, the module is authorized to operate at a speed equal to VMAX + 10%, on the transitories, in order to reduce following error.

TLX DS 57 PL7 xxE

Configuration

Maximum setpoint

Introduction

Adjusting the variable speed controller

Example

The maximum setpoint UMAX is the voltage which has to be applied to the variable speed controller, in order to reach a speed equal to the maximum speed.

In the absence of any particular speed constraint, the variable speed controller can be adjusted to obtain the maximum speed for a voltage as close as possible to, but less than 9 V.

Limiting voltage to 9 V enables a reserve to be made available during transitory periods allowing a surge speed to be attained. If there are no constraints imposed by the mechanics, or by the maximum acceptable frequency, choose the following value: Maximum setpoint = 9000 mV

We would like to control an axis with the following characteristics:

Encoder

1000 points/turn

Motor

Moving part to be commanded

(Maximum speed = 30 mm/s)

Reduction 1/5

Desired maximum linear speed of 30 mm/s, or 1800 mm/m. Thread of 5 mm.

The axis is controlled by a motor capable of 3000 rev/min, which drives a ball screw via a speed reducer with a ratio of 1/5. The encoder is on the motor shaft. Let us assume that it is an incremental encoder without multiplication by 4.

l l

The RESOL parameter (distance covered by the moving part between 2 encoder increments) is equal to: Ne x Thread / N = 1/5 x 5 / 1000 = 1 microm

The maximum operating speed is 1800 mm/m,

Maximum setpoint is the voltage value at which maximum speed can be reached.

Considering the reduction ratio (1/5) and the thread size (5 m), the maximum linear speed (1800 mm/min) corresponds to a motor speed of 1800 rev/min.

If the variable speed controller is adjusted to reach a speed of 3000 rev/min with an input voltage of 10 V; in order to reach 1800 rev/min, the voltage must be 6 V

(maximum setpoint = 6000 mV).

Consistency of parameters

The consistency of the RESOL, Maximum speed and Maximum setpoint parameters must be ensured, otherwise inconsistent control loop behavior will result.

Introduction

Inversion possibilities

Using the inversion parameter

The inversion parameters means that it is not necessary to reconnect the analog output when the axis is moving in the opposite direction to that required. These parameters define the setpoint inversion between the digital/analog converter (D/A converter) output and the variable speed controller and / or the measurement inversion (for an incremental encoder).

The measurement inversion allows you to define the direction of measurement for an encoder rotation direction.

The inversion possibilities are as follows:

Sequence control

Introduction

Enabled sequence control

Disabled sequence control

The Sequence control parameter is used to define the action to be taken when movement without stop (G01, G11 ou G30) is not followed by a movement command.

If the sequence control is enabled (default value): l G01, G11 and G30 movements not followed by a movement command are stopped (equivalent to a STOP command) and a command refusal is generated.

In this case, the movements without stop cannot be sequenced by synchronization on the DONE bit.

l G01, G11 and G30 movements followed by G05, G07 or G62 movements are stopped if this second command is not itself followed by a movement command.

If sequence control is disabled, G01, G11 and G30 movements not followed by a movement command continue at their target speed.

Reference point

Introduction An incremental encoder does not measure the position but supplies a number of pulses proportional to a movement.In order for this movement to be transformed into a position, a known value must assigned to a particular point on the axis (usually chosen as 0).This operation is called setting a reference point.An axis which has been given a reference point, is classed as referenced.

Reference point field

The Reference point field defines the type and direction of the reference point (only when an incremental encoder has made the position measurement).

The type is defined by using 2 source detection inputs :zero marker input and cam input.

→

Confirm command or by activating the associated icon:

Invalid configuration parameters

If one or several parameter values are outside the permitted limits, an error message is displayed to signal the invalid parameter.

For example the Distance value of the Initial resolution field is invalid:

Confirm i

Cannot validate:

Error in parameters of configuration:

Initial resolution distance not valid

The invalid parameters must be corrected before your configuration can be confirmed.

Note: In the configuration screens, invalid parameters are shown in red. The grayed out parameters can not be modified because they depend on invalid parameters (for example, an invalid resolution prevents the lower and upper limits from being entered).

Configuration

Invalid adjustment parameters

The first time the configuration is confirmed, the adjustment parameters are initialized. If subsequent to modifications made to the configuration values, the adjustment parameters are no longer correct, an error message is displayed to signal the affected parameter.

For example, the soft stops are incompatible:

Introduction

Bit objects and words

Each axis control module channel (axis) is programmed by using: l l the SMOVE function for movements in automatic mode, the bit objects (%I et %Q) and words (%IW, %QW et %MW), associated with the module to be defined: l l l selection of operating modes, movement commands, except for automatic mode, monitoring of the axis and module operating state.

The bit objects and words can be accessed by their address or their symbol.The symbols are defined in the variable editor, which proposes a symbol name for each object by default.

Programming

Operating modes

Introduction You can operate each axes control channel in 4 operating modes:

Operating mode

Automatic (AUTO)

Description

This mode is used for the execution of movement commands controlled by the SMOVE functions.

Manual (MANU) This mode is used to control the moving part visually from a front panel or human machine interface terminal. The commands can be accessed by the %Q output bits.

Loop control disabled

(DIRDRIVE)

The output behaves like a digital / analog converter in this mode. The control loop is inoperative.

During adjustment this mode is used to analyze the behavior of the axis independently of the control loop.

Measurement (OFF) In this mode, the channel does not check the moving part. It only returns information on position and current speeds.

This mode is forced at start-up if the axis is configured and not faulty.

Mode selection Modes are selected: l l using the MODE_SEL (%QWxy.i.0) word, or by the debugging screen selector.

The following table indicates the selected mode, according to the %QWxy.i.0 word value:

Value

Selected mode

OFF

DIRDRIVE

MANU

AUTO

Description

Measurement mode, analog output inhibition.

Loop control disabled mode.

Automatic mode.

For all other values of %QWxy.i.0, the OFF mode is selected.

Changing mode during a movement

Changing mode while a movement is in progress (DONE bit: %Ixy.i.1 at 1) stops the moving part. When the moving part is actually stopped (NOMOTION bit: %Ixy.i.1 at

1) the new operating mode is then activated.

Note: Only commands concerning the current mode are examined. The other commands are ignored (except when an SMOVE function is performed in manual mode).

N_Run defines the movement number (between 0 and 32767). This number identifies the movement carried out by the SMOVE function.

In debugging mode, this number is used to recognize the current movement.

G9_ defines the movement type:

Coordinates for reach position

X defines the coordinates of the reach position or where the moving part must aim for (in the case of non-stop movement). This position can be: l l immediate, coded in a %MDi internal double word or %KDi internal constant (this word can be indexed).

This value is expressed as a unit defined by the Length Unit (for example; microm).

Note: In the case of G14, G21 and G62 instructions, this parameter represents the reference point value.

Speed of moving part

F defines the speed at which the moving part travels. This speed can be: l l immediate, coded in a %MDi internal double word or %KDi internal constant (this word can be indexed).

The speed unit is deduced from the selected length unit:

Speed = u x 1000 / min where u = unit length chosen.

For example, if the microm is chosen as the length unit, the speed unit will be: microm x 1000 / min -> mm / min

Introduction

Types of movement

3 types of movement category can be programmed: l l l movements to a position (instruction codes 01 and 09), movements until event detection (instruction codes 10 and 11), reference points (instruction code 14).

The target position and speed must be set while programming these movements.

Acceleration parameters (e.g. rectangular, trapezoidal or triangular) are defined in the configuration.

With a limited machine, types of movement are as follows: l Absolute in relation to the machine homing point (code 90).

Introduction

Types of movement

3 types of movement category can be programmed: l l l movements on a position (instruction codes 01 and 09), movements until event detection (instruction codes 10 and 11), reference points (instruction code 14).

The reach position and speed must be set while programming. Acceleration parameters (eg rectangular, trapezoidal or triangular) are set in the configuration.

Whatever the current position and target may be, it is always possible to reach the objective position in + direction as well as – direction. There are 3 possible ways to go from point A to point B: l l l ascending position movement (movement 1), descending position movement (movement 2), for the shortest movement: the module decides on the direction (movement 3)

The required direction of movement is specified by the speed sign.

Movement 1

0 A B Mod-1

Movements 2 and 3

With an infinite machine, movements can be of the following type: l Shortest movement in relation to the machine homing point (code 90). In this case, the shortest path determines the direction of movement.

Shortest movement in relation to stored PREF1 position (code 98).

For example, SMOVE %CH102.0 (1,98,09,45000,1000,0) targets (45000 +

PREF1) value.

In opposite direction in relation to stored PREF1 position (code 68).

For example, SMOVE %CH102.0 (1,68,09,45000,-1000,0,0) targets (45000 +

PREF1) value while moving in – direction.

For example, SMOVE %CH102.0 (1,68,09,45000,1000,0) targets (45000 +

PREF1) value while moving in + direction.

125

Programming l Relative in relation to current position (code 91). In this case, direction of movement is determined by the X parameter sign (position increment).

Example : SMOVE %CH102.0 (1,90,09,15000,1000,0)

Speed (mm / min)

Note: The value targeted by G68 or G91 is calculated in relation to the modulo.

(1000 + PREF1) Mod ModuloValue and (X + 15000) Mod ModuloValue are targeted in the examples. Mod is the Modulo mathematical operator.

For example, if PREF1 = 40000 and modulo = 60000 : 45000 + PREF1 corresponds to 25000.

Programming l l l l l

Command G32 is a preparation command. It can be activated in the same PLC cycle as a G30 command, without monitoring the NEXT and DONE bits.

The reactivating command G32 does not have to be reactivated when the approach speed remains unchanged, as the speed is stored. On the other hand, it is mandatory to send at least one G32 command before executing a G30 command.

If it is not followed by a movement command, instruction G30 triggers a movement without stop whose behavior is identical to instruction G01. If instruction G30 is not followed by a movement command and if a sequence control is requested, it will cause a command refusal.

If the moving part is in motion, instruction G30 must not change the direction of movement.

Instruction G30 is normally followed by a G09 instruction (figure 1). If this sequence causes a change in direction, the process stops and inverts in order to obtain the value G09 (figure 2).

Programming an await event

Instruction The await event instruction is as follows:

Instruction

Await event

Instruction code

Icon

For an infinite machine

With an infinite machine, the G05 instruction is also used to await the crossing of a l l number of modulo.

The choice is determined by the bit 13 value of parameter M: bit 13 = 0, await event, bit 13 = 1, await modulo number.

Event associated with the command l l

The event associated with command G05 can be: l a rising or falling edge (depending on the choice made in the Event field in the configuration screen) on dedicated event input, associated with the channel which controls the axis, a rising edge of the EXT_EVT bit (%Qxy.i.10) generated by the program, a number of modulo crossings (for an infinite machine). For example, awaiting 10 modulo crossings with activation of the event task:

SMOVE %CH102.0 (1,90,05,0,10,16#2000)

Event task

This instruction is used to await an event within a Time Out (in ms), defined in the parameter F. If an event does not appear within this Time Out period, the await command is then deactivated. If parameter F is defined at 0, the wait is without a time limit.

The G05 instruction can activate an event task on detection of an event, if bit 12 of parameter M is set at 1.

The TO_G05 bit is set to 1 when the Time Out has elapsed without an event being detected. For example, an event waits with a Time Out period of 1.5 s and with activation of the event task:

An indexed position is used to resolve repetitive movements.For example, let us assume that the elementary movement sequence below has to be performed 9 times: l l l movement until the edge of the part is detected (2), movement up to position 2000 in relation to the edge of the part (3), movement up to position 1000 in relation to the edge of the part (4), l movement up to the edge of the part (5).

In this example, it is assumed that the reference point is already set and the moving part is in the source position.

Sequencing movement commands

Producing a trajectory

Buffer memory

A trajectory is produced by programming a succession of elementary movement instructions (SMOVE function).

Each elementary SMOVE command must only be performed once. It must be programmed: l either in Grafcet:in one programmed step, on activation or deactivation, l in structured text or ladder language, on the rising edge of a bit.

A function execution report is provided by the module using the NEXT and DONE bits.

The TSX CAY module features a mechanism which is used to sequence movement commands.

Each axis of the TSX CAY module has a buffer memory, which can receive 2 movement commands, in addition to the one it is in the process of executing.Thus when a movement in progress has finished, it moves directly on to the first command in the buffer memory.

Command sequence:

SMOVE

SMOVE %CH102.0 (01,90,01,...)

SMOVE %CH102.0 (02,90,01,...)

SMOVE %CH102.0 (03,90,01,...)

Programming

Sequencing 2 commands l l

2 movement commands may be sequenced as follows : instantaneously if the first movement is without stop, as soon as the moving part is in the target window or after time delay TSTOP has elapsed (which is defined in the stop control on parameter adjustment screen) if the first movement is with a stop.

For the sequencing to be instantaneous, the execution time for the instruction in progress must be longer than the master task period.

Note: A new command must only be sent to the module if the buffer memory associated with the axis to be controlled is not full.

Bits associated with a sequencing mechanism

The bits associated with the sequencing mechanism are as follows:

Addressing

NEXT (%Ixy.i.0)

DONE (%Ixy.i;1)

Description

Indicates to the user program that the module is ready to receive the next movement command.

Indicates that execution of the command in progress is complete and that there are no new commands in the buffer memory.

TH_PNT (%Ixy.i.10) Indicates that the position target value has been reached.

AT_PNT (%Ixy.i.9) Indicates that the moving part has reached the target point: l l by an INC command in manual mode, by a movement command with stop in automatic mode,

For a movement with stop, this bit is set to 1 as soon as the moving part enters the target window.

This bit is not set to 1, following a JOG command, reference point or

STOP during a movement.

Note: The program must always test the NEXT bit, or the DONE bit before executing an SMOVE command, except in the case of a G32 command which can be immediately followed by another command.

The SYNC_N_RUN (%IWxy.i.8) word periodically supplies information on the number of steps in progress, in order to carry out movement sequencing.

Programming the recalibration on the fly function

Introduction This function, available with an incremental encoder, updates the current position of the moving part each time the recalibration on the fly input detects a rising edge in a positive direction or a falling edge in a negative direction.

It has been specifically adapted for axes where the moving part is susceptible to slip, or in other words where the position value no longer reflects the true position.

This function is confirmed in the configuration screen.

Recalibration on the fly function

When the event takes place, the axis control module preselects the current value to the RE_POS value and compares the current position with the recalibration value

RE_POS (%MDxy.i.43), defined in the recalibration screen (or by the program).

l If the comparison indicates that the current value is outside of the tolerances defined by RE_WDW (%MDxy.i.51), a fault is signaled: REC_FLT bit

(%MWxy.i.3:X12).

Movement slaved to another TSX CAY •1 axis

Introduction

Slaving

This function is used to slave the position of an axis (called the slave axis) to the position of another axis from the same module (called the master axis).

The master axis is always the axis 0. A 2 axis module can have one master axis and one slave axis. A 4 axis module can have one master axis and up to 3 slave axes.

This position tracking function is confirmed in the configuration screen. At programming level, the slave axis is slaved to the master axis when the SLAVE bit

(%Qxy.i.17) of this axis is set at 1. The %Ixy.i.36 bit indicates that the slave axis is operating in tracking mode.

An axis is slaved either to the measured position or to the master axis position setpoint (choice defined in configuration). A RATIO1 / RATIO2 ratio is applied in order to obtain the final setpoint. These 2 parameters are defined during configuration.

In order to indicate that the slave axis is tracking the master axis correctly, the

AT_PNT (%Ixy.i.9) bit of the slave axis is at 1 when the tracking error of the latter is lower than DMAX2.

For example, Ratio = 3/4, with slaving to the master axis setpoint.

Movement slaved to another TSX CAY •2 axis

Introduction

Slaving

This function is used to slave the position of an axis (called the slave axis) to the position of another axis from the same module (called the master axis).

The master axis is always the axis 0. A 2 axis module can have one master axis and one slave axis. A 4 axis module can have one master axis and up to 3 slave axes.

This position slave function is confirmed in the configuration screen. At programming level, the slave axis is slaved to the master axis when the SLAVE bit (%Qxy.i.17) of this axis is set at 1. The IN_SLAVE bit (%Ixy.i.36) indicates that the slave axis is operating in tracking mode.

An axis is slaved either to the measured position or to the master axis position setpoint (choice defined in the configuration screen). A RATIO1 / RATIO2 ratio and an Offset are applied to obtain the final setpoint. These 3 parameters are defined in the adjustment screen.

The slave axis is related to the master axis in the following way:

SlavePositionSetpoint = MasterPosition x (Ratio1 / Ratio2) + SlaveOffset

In order to indicate that the slave axis is tracking the master axis correctly, the

AT_PNT (%Ixy.i.9) bit from the slave axis is set at 1 when the slave has caught up with the master and remains close to it (tracking error of the latter is lower than

DMAX2) for more than TSTOP ms

Differences from the TSX CAY •1

Module

The tracking function of a TSX CAY•2 module differs from the TSX CAY •1 in the following ways: l the ratio can be modified from the application or by the PL7 in recalibration mode

(for the TSX CAY •1 module the ratio is set during configuration, l the offset enables to slave axis to slave itself to the master axis, whatever the master’s position. This allows object tracking applications to be set up where a tool-carrying axis has to be slaved to a permanently moving axis (conveyor) for the transportation of objects (glue application, etc.).

The offset value can be modified from the application or from the PL7 software in recalibration mode. The TSX CAY •2 module provides an alignment or locking device in order to avoid a ‘surprise’ during the switch to slave mode.

The function calculates the offset as follows:

SlavePosition = MasterPosition X Ratio + Offset

The configuration parameter Automatic offset is used to select the operating mode.

The signed ratio value advances from 0.01 and 100.

152

TLX DS 57 PL7 xxE

Programming

Parameters associated with the master mode

- slave

The parameters of the master – slave mode are as follows: l %MWxy.i.29 (Ratio1) and %MW xy.i.30 (Ratio2) which determine the value of the l master – slave ratio,

%MDxy.i.55 (SlaveOffset) : offset value when the Automatic offset option has not been selected during configuration, l InternalSlaveOffset: offset value (calculated by the module and not accessible by the user) when the Automatic offset option has been selected during configuration,

Execution condition

For the

DRIVE_OFF mode l The master axis is configured in automatic or manual mode in the framework of l l l a setpoint follower.

The slave axis is referenced in automatic mode.

No blocking fault is detected.

The master axis must be referenced within the framework of a measurement follower (the master being situated indifferently in one of the 4 modes).

If the calculated setpoint overshoots the axis soft stops, the moving part stops and the command is refused.

SlavePositionSetpoint = MasterPosition (1) x Ratio1 / Ratio2 + SlaveOffset (or

InternalSlaveOffset)

(1) according to configuration.

This mode is used to slave a slave axis to a master axis. In this case, the slave is declared a measurement follower.

Meaning of the

AT_PNT bit and

DMAX2 parameter

The DMAX2 parameter defines the precision threshold.

This value is particularly useful in the object tracking applications where the slave axis goes into a recovery phase before satisfying the condition:

(MasterPosition x Ratio + Offset) - DMAX2 < or = (SlavePosition) < or =

MasterPosition x Ratio + Offset) + DMAX2

As soon as the condition is satisfied over a period at least equal to the value of the

T_STOP parameter, the AT_PNT bit takes the value 1, to signify that the slave axis has caught up.

Programming

Important

Specifications l l l l l

For the calculated slave axis position setpoint to be valid, you must make sure that the slave axis is already at the Master x RATIO position before switching this axis to slave mode.

Reference point commands on the master axis must be avoided when there are slave axes (risk of tracking error fault on the slave axis).

l l

In Tracking mode: the TH_PNT, NEXT information bits are not managed, the PAUSE command is not active, l SMC modifications are not taken into account (SMC = 1000).

When a slave axis is slaved to a master axis, the slave tries to catch up with the master by the shortest possible route. For this reason, the tracking error must always be less than half the slave modulo value.

During configuration you can specify that the link between slave and master must be made with no movement.

In this case, the slave does not take the SlaveOffset parameter into account, and calculates an InternalSlaveOffset parameter (which is not communicated to the application), in order to inhibit all slave movements, at the point when it becomes a slave, while the master is immobile.

These applications are made up of: l l an infinite axis or "master axis" which moves continuously, an axis which is sometimes controlled by a master, and sometimes independent.

Movement slaved to an external setpoint

Introduction

Example

This function is used to slave the position of an axis to a position written by an application program in the double word PARAM (%QDxy.i.2).

It provides a means of slaving an axis to a pre-programmed trajectory.

It can also be used to control a module axis so that the refresh rate of the slave axis setpoint is equal to the period of the task in which the modules are managed.

Setting the EXT_CMD (%Qxy.i.18) bit to 1 enables this function. The IN_EXT_CMD

(%Ixy.i.37) status bit indicates that the slave axis is effectively performing the tracking function.

In this mode with TSX CAY •2 and TSX CAY 33 modules, you can control the discrete event output:

Deferred PAUSE function

Introduction The PAUSE command (%Qxy.i.16) is used to suspend movement sequencing. It only becomes active when the moving part has come to a stop, or in other words at the end of a G09 or G10 instruction.

l l

The next movement starts as soon as the PAUSE command is reset to 0.

When at 1, the ON_PAUSE (%Ixy.i.33) bit signals that the axis is in PAUSE state.

This function has 2 possible uses: block to block execution of the movement program, synchronizing axes from the same axis control module.

Block to block execution of the movement program

If the instruction in progress is an instruction with stop, activating the PAUSE command in the debugging screen in automatic mode, or setting the PAUSE

(%Qxy.i.16) bit to 1 puts the module in waiting status after the instruction in progress is finished: movement sequencing stopped.

The movements without stop are stopped when they are terminated by reaching the soft stop.

By successively activating and deactivating the PAUSE command it is thus possible to execute block to block movements in order to facilitate debugging.

Synchronizing several axes

Using the program to set the PAUSE bit (%Qxy.i.16) for each axis at 1 after the instruction in progress is complete puts the module in waiting status.

When the PAUSE bit is reset to 0, the module continues carrying out the instructions.

Step by step mode

Introduction

Activating step by step mode

This mode is used to execute a sequence of movements by stopping after each elementary instruction (step).

Movements without stop are thus transformed into movements with stop at the same value and speed (except for instruction G21, which never stops). For the G30 command, the speed used is the approach speed.

Step by step mode is activated by setting the MOD_STEP (%Qxy.i.19) bit to 1.

The ST_IN_STEP (%Ixy.i.39) bit indicates that the mode is active, or in other words that the command in progress has been modified to be executed in step by step mode.

A rising edge on the NEXT_STEP bit (%Qxy.i.22) is used to start the next step.

Feed HOLD function

Introduction This function is used to stop the moving part in automatic mode, while ensuring that, on a resume movement command, it follows the programmed trajectory (with no risk of the command being refused).

Activating the function

The feed HOLD function is activated: l by the program: by assigning a value of 0 to the SMC word (%QWxy.i.1), speed modulation coefficient, l by the debugging screen: by assigning a value of 0 to the speed modulation coefficient parameter SMC.

It stops the moving part according to the programmed deceleration.

The feedhold status report is indicated by the IM_PAUSE bit (%Ixy.i.34).

Deactivating the function

The feed HOLD function is deactivated: l by the program: by reassigning the initial value (>0) to the SMC word, speed modulation coefficient, l By the debugging screen: by reassigning the initial value (>0) to the speed modulation coefficient parameter SMC.

It reinitializes the interrupted movement at a speed corresponding to:

Event processing with an independent axis

Introduction The TSX CAY module channels are able to activate an event task.To do this, the function must have been enabled on the configuration screen by associating an event processing number with the channel.

Activating an event task

Variables that can be used by the event task

The following instructions trigger an event transmission, which activates the event task: l Movement until the event, codes 10 and 11:the event processing application is activated, on event detection.

l Await event, code 05:the event processing application is activated, on instruction completion.

l Storage of current position on event occurrence, code 07 :the event processing application is activated on completion of storage of the position PREF1 or l

PREF2.

Modulo crossing for an unlimited axis: the event processing application is activated on every modulo crossing during a movement.Event processing activation must be enabled by setting the VALIDEVTMOD parameter

(%MWxy.i.62:X0) to 1.

The event processing application is activated if bit 12 of parameter M of the SMOVE function associated with the instruction is set at 1.

l l l l l

If several event sources are chosen, the following bits are used to determine the source to trigger event processing application:

EVT_G1 (%Ixy.i.50): G10 or G11 end on event,

EVT_G05 (%Ixy.i.48): G05 end on event, l l

TO_G05 (%Ixy.i.49): G05 time-out elapsed,

EVT_G07 (%Ixy.i.47):Storage of position, l EVT_MOD (%Ixy.i.51):Modulo crossing.

The OVR_EVT bit (%Ixy.i.46) is used to detect a delay in event transmission or an event loss.

Managing the operating modes

On module power-up

On module power-up or during run through, the TSX CAY module performs selftests with the outputs in safety position (outputs to 0).

On completion of the self-tests:

Self-tests Module

If the self-tests have not detected an error.

The module tests the configuration with the outputs in the safety position. If the configuration is correct, the module goes into measurement mode (OFF).

If the self-tests have detected an error or if the configuration is incorrect.

The module signals a fault and retains the outputs in the safety position.

PLC in RUN All the configured channel operating modes are useable.

Switching the

PLC from RUN to

STOP

On switching the PLC from RUN to STOP or on loss of processor / module communication, the moving part decelerates and stops and the module goes into measurement mode (OFF).

Note: The %S13 bit is used to detect the PLC switching to STOP. It is set to 1 during the first cycle after the PLC enters RUN mode.

Change of configuration

(reconfiguration) l l l l l

The moving part decelerates and stops.

The channel deconfigures.

The module tests the new configuration with the outputs in the safety position.

If the new configuration is correct, the module goes into measurement mode

If the configuration is incorrect, the module signals a fault and retains the outputs in the safety position.

Power outage and restart

On power outage, the moving part stops.

On a cold start or warm restart, the channel configuration is automatically sent to the module by the processor. The module goes into measurement mode (OFF) then into the mode requested by the program.

Fault management

Introduction

Fault types

Fault monitoring is essential for position control, due to the inherent risks associated with active moving parts.

The module automatically carries out checks internally.

l l

The module detects 4 fault types: l The module faults.These are internal hardware faults within the module. All the axes controlled by the module are thus affected when this type of fault occurs.

They can be detected during self-tests (on module reset) or during normal operation (I/O fault).

Hardware channel faults external to the module (for example, encoder break).

Application channel faults associated with the axes (for example, tracking l error).

Faults are constantly checked at axis level once the axis is configured.

Command refused channel faults.These are the faults, which may occur during execution of a movement command, a configuration transfer, an adjustment parameter transfer or an operating mode change command.

Note: The axis monitoring parameters may enable or inhibit the checking of some faults.These monitoring parameters can be adjusted in the adjustment screen.

In loop control disabled mode (DIRDV), checking of application faults is inhibited,

In measurement mode (OFF), checking of application faults except soft stop faults, is inhibited

Programming

Levels of severity

Fault programming

Fault signalling

Faults are classed according to 2 levels of severity: l The blocking or critical faults which cause the moving part to stop in the case l l l l of an axis fault or moving parts managed by the module in the case of a module fault.The following processes then occur: the fault is signaled, the moving part slows down until analog output is zero, deactivation of the variable speed controller enable relay, erasing of all stored commands, l wait for acknowledgment.

The fault must have disappeared and been acknowledged before the application can be re-started.

l Non-critical faults which cause a fault to be signaled without stopping the moving part. The action to be taken when this type of fault is encountered must be programmed in PL7.

The fault signal disappears when the fault has disappeared and has been acknowledged (the acknowledgment is not stored and only comes into effect if the error has disappeared).

Faults can be viewed, corrected, and acknowledged from the debugging screen.

However it can be useful to be able to control the moving part and correct faults from a terminal during operation. For this purpose, all the information and commands necessary are available within the application.

The module offers a wealth of information in the form of bits and status words, all l l accessible through the PL7 program. These bits are used to process faults in hierarchical order: to act on the main program, to simply signal the fault.

Note: With a blocking fault, it is advisable to stop the sequential processing which is associated with the axis, and correct the fault by controlling the moving part in manual mode.Correction of the fault must be followed by a fault acknowledgment.

Fault acknowledgment

When a fault appears: l The fault bits AX_FLT, HD_ERR, AX_ERR and the status word extract bits affected by the fault are put in position 1.

l If it is a blocking fault, the AX_OK bit is set at 0.

When the fault disappears, all fault bits retain their current status.A fault is stored until acknowledgement is obtained by setting the ACK_DEF %Qxy.i.8 bit to 1 (or by resetting the module).The acknowledgment has to be made after the fault has disappeared (except for soft stop errors)

If several faults are detected, the acknowledgment order will only act upon faults which have actually disappeared.Faults that are still present must acknowledged again after their disappearance.

Note: Faults can also be acknowledged on PLC initialization, or when a new correct command is accepted in the case of a command refused fault

Description of Application Faults

Introduction

Soft stops

These faults are indicated by the AX_ERR bit (%Ixy.i.5). The parameters can be accessed by the Adjustment screen of the configuration editor. There is no fault checking associated with the soft stops for the unlimited axes (modulo).

The following table shows the cause, indication and the solution if a Soft stops fault should occur. This is a blocking fault and cannot be deactivated.

Cause

Result

Indication

Remedy

The moving part is no longer situated between the 2 thresholds: lo and hi software limits (this check is activated as soon as the axis is referenced)

Software hi limit: SL_MAX (%MDxy.i.31)

Software lo limit: SL_MIN (%MDxy.i.33)

Moving part is forced to stop

%MWxy.i.3:X8 bit: Software hi limit exceeded

%MWxy.i.3:X9 bit: Software lo limit exceeded

Acknowledge the fault and in manual mode release the moving part outside of the soft stops within the valid measurement space. To do this you must check: l l l l l that there is no movement in progress, that manual mode is selected, that the STOP command is at 0, that the axis on which this command is carried out is referenced, that there is no other fault with stop on the axis.

The moving part can either be repositioned manually or by using the

JOG+ and JOG- commands.

Description of command refused faults

Introduction

Command refused

A command refused fault is generated each time a command cannot be executed.

This command is either not compatible with the axis state, with the mode in progress or at least one of the parameters is not valid.

These faults are indicated by the Refus Cde LED on the debugging screens. At channel level, the DIAG key allows you to identify the source of the command refusal. This information can also be accessed by the program with the CMD_NOK

(%Ixy.i.6) bit and CMD_FLT (%MWxy.i.7) word.

Managing manual mode

Introduction

Manual mode selection

Execution of manual commands

Manual mode can be selected and controlled from the debugging screen, but also via the application program from the front panel or human-machine interface/ monitoring terminal.

In this case, the dialog is programmed in ladder, instruction list or structured text language, with the help of elementary commands (movements, reference points etc.).

Manual mode is selected by assigning the value of 2 to the MOD_SEL (%QWxy.i.0) word.

Switching from the current to manual mode forces the moving part to stop of there is a movement in progress. Manual mode is engaged as soon as the moving part has stopped.

When the command to switch to manual mode is taken into account, the IN_MANU

(%Ixy.i.22) bit is set to 1.

Elementary commands associated with manual mode and accessed via command bits %Qxy.i.j are as follows: l Visual movement in positive direction JOG_P (%Qxy.i.1) and in negative l direction JOG_M (%Qxy.i.2).

Incremental movement in positive direction INC_P (%Qxy.i.3) and in negative direction INC_M (%Qxy.i.4).

General execution conditions for commands in manual mode

Programming l l l l

The following conditions must be fulfilled in order to carry out commands in manual mode:

Target position within soft stops.

Axis without blocking fault (AX_OK bit: %Ixy.i.3 = 1).

No command in progress (DONE bit: %Ixy.i.1 = 1).

STOP (%Qxy.1.15) command inactive and ENABLE (%Qxy.i.9) bit for variable speed controller safety relay set to 1.

Note: Except for, in the case of soft stop fault, JOG_P and JOG_M commands and after fault acknowledgment.

Movement stop l l l

A movement stop can be caused by: l Appearance of a STOP (%Qxy.i.15) command or the ENABLE (Qxy.i.9) bit being set to 0.

Appearance of a blocking fault.

Change in operating mode.

Programming

Visual movement commands

Introduction To carry out a movement visually, you must use the manual commands JOG_P and

JOG_M.

The JOG_P (%Qxy.i.1) and JOG_M (%Qxy.i.2) bits give the command for the moving part to move in a positive or negative direction. The operator must visually follow the position of the moving part. Movement occurs as long as the command is present, and a STOP command or a fault does not inhibit the command.

For limited axes, the JOG_P and JOG_M commands cause an automatic stop at the latest at a distance from the soft stops equal to the target window distance.

JOG_P and JOG_M commands are taken into account on edge and are kept active on status, regardless of whether the axis is referenced or not.

TLX DS 57 PL7 xxE

Programming

Movement speed Movement occurs at the speed of the manual mode MAN_SPD, defined in the adjustment screen (or in the double word %MDxy.i.35).

The speed can be modulated during a movement via the SMC coefficient

(%QWxy.i.1).

Any movement speed greater than VMAX (maximum axial speed defined in configuration) is limited to the value of VMAX.

Speed of moving part:

Time

Notes on JOG_P and JOG_M commands l l

JOG_P and JOG_M commands are used to release the moving part when a soft stop fault is detected. This happens after prior acknowledgment of the fault.

If the JOG_P or JOG_M bit is set to 1 during operation in manual mode, this command is ignored. It will only be taken into account after the bit has been set at 0 then reset to 1.

TLX DS 57 PL7 xxE

181

Programming

Incremental movement commands

Introduction INC_P and INC_M manual commands must be used to carry out an incremental movement.

INC_P (%Qxy.i.3) and INC_M (%Qxy.i.4) bits give the command for movement by incrementation of the position of a moving part in a positive or negative direction.

The value of the PARAM position increment is entered either in the %QDxy.i.2 double word or in the debugging screen of the TSX CAY module.

In addition to the general execution conditions in manual mode, the INC_P and l l

INC_M commands are active on a rising edge when: the axis is referenced for limited run-time machines.

The target position is between the soft stops.

Movement speed Movement occurs at the speed of the manual mode MAN_SPD, defined in the adjustment screen (or in the double word %MDxy.i.35).

The speed can be modulated during a movement via the SMC coefficient

Reference point command

Introduction If an incremental encoder is being used, a reference point can be set with the

SET_RP command.

Bit SET_RP (%Qxy.i.5) carries out a manual reference point with movement.

The type and direction of the reference point are set in the Reference Point parameter on configuration. The source value is set on the adjustment screen by the

PO Value parameter (or by the RP_POS double word) %MDxy.i.41).

Approach speed Approach speed is the manual speed MAN_SPD set on the adjustment screen (or by %MDxy.i.35 double word) multiplied by the CMV speed modulation coefficient.

The speed of the reference point varies according to the type of reference point chosen.

Any movement speed greater than VMAX (maximum axial speed defined in configuration) is limited to the value of VMAX.

Forced reference point command

Introduction If an incremental encoder is being used, a forced reference point can be set with the RP_HERE command.

The RP_HERE (%Qxy.i.6) forces a reference point without movement to the value set in the PARAM parameter. This value is entered either in the %QDxy.i.2 double word or in the debugging window for the TSX CAY module.

The forced reference point command references the axis without generating a movement.

Note: The RP_HERE command does not modify the value of the RP_POS parameter.

The value of the PARAM parameter must be between the soft stops.

All blocking faults are tolerated while this command is being carried out (except for an encoder break fault).

184

TLX DS 57 PL7 xxE

Programming

Cancel references command

Introduction If an absolute encoder is being used, a reference point can be canceled using the

SET_RP command.

Cancellation of references needs to be carried out before a reference command can be given.

An edge on the SET_RP(%Qxy.i.5) bit is used to change the axis to a nonreferenced state, in order to be able to shift the moving part without provoking a soft stop fault. However it is not possible to overshoot, in either direction, to a position outside the measurement area of the absolute encoder.

Parameter ABS_OFF (%MDxy.i.53) is forced to 0

Programming

Referencing and offset calculation command

Introduction

Assisted offset

If an assisted offset absolute encoder is being used, referencing and offset calculations can be set using the RP_HERE command.

An edge on the RP_HERE (%Qxy.i.6) bit is used to change the axis to a referenced state.

If the encoder has been declared in assisted offset mode (any reference must be cancelled), the offset is recalculated at the current point as being at position defined in the PARAM parameter. This position is entered either in the %QDxy.i.2 double word or in the debugging screen of the TSX CAY module.

In this case, it is essential to force adjustment parameters to be saved so as not to l l lose them on restart:

Either use Save parameters from the adjustment screen.

Or via the application by calling the SAVE_PARAM function.

Note: The value of PARAM must be between the soft stops.

The offset calculation is refused if an adjustment is in progress or if the axis is referenced.

If resolution is modified, the offset must be recalculated.

Programming

Managing loop control disabled mode (DIRDRIVE)

Introduction DIRDRIVE (loop control disabled) mode is used to free the axis from slave mode.

The axis acts as a digital/analog converter (D/A converter) and the position loop is inoperative.

Axis behavior can be analyzed independently of the process control loop.

Selection of loop control disabled mode

Loop control disabled mode is selected by assigning the value of 1 to the MOD_SEL

%QWxy.i.0 word.

When a change of mode is requested, the moving part first stops then the mode is actually changed. When the command to change to loop control disabled mode is taken into account, the IN_DIRDR %Ixy.i.21 bit is set to 1.

Execution of commands in loop control disabled mode

The loop control disabled mode features the movement command DIRDRV

%Qxy.i.0.

The drive is controlled at a voltage of between -UMAX and +UMAX (the value UMAX is defined in the configuration screen). It is expressed in mV. Application of this setpoint is rounded off into multiples of 1.25 mV (For example, if 1004 mV is requested, the setpoint will be rounded down to 1003.75 mV, and the display screen will show 1003 mV).

The voltage setpoint is periodically sent by the variable PARAM %QDxy.i.2. The variable sign gives the direction of movement. The software fault checks are inhibited (excepted for soft stop checks if the axis is referenced).

In order to protect the mechanics during a setpoint change, the acceleration/ deceleration value is respected when switching to a new value.

Managing measurement (OFF) mode

Introduction

Selection of measurement mode

The measurement mode must be used each time the moving part has to pass outside module control (moving part moved by hand or controlled by an exterior device). In this mode the module remains passive, but continues to update the position (%IDxy.i.0) and current speed (%IDdxy.i.2) information bits.

Measurement mode is selected by assigning the value of 0 to the MOD_SEL

%QWxy.i.0 word.

The module also selects measurement mode while the PLC is in STOP mode. By default, it is selected following channel configuration.

Execution of commands in measurement mode

OFF mode is not associated with any movement commands.

Movement of the moving part is not monitored and software fault checks are inhibited (except soft stop checks). The position loop is inoperative.

The variable speed controller enable relay is unlocked whatever the status of the

ENABLE (%Qxy.i.9) bit.

Modules

TSX CAY 22/42 and TSX CAY 33 l l

This parameter is concerns absolute encoders only. It is used to make the real position of the moving part coincide with the position provided by the encoder (shift from zero).

l In direct offset the offset value must be entered, expressed in encoder points, l into the ABS_OFF parameter.

In assisted offset , use the RP_HERE and SET_RP commands.

This parameter can only be modified if direct offset has been chosen in the configuration.

The encoder offset is defined as follows:

Encoder offset = value to be added (expressed in number of encoder points) to the measurement provided by the absolute encoder, in order to obtain the real measurement.

Limits are as follows: -2

n-1

+ 1 to 2

n-1

- 1, where n= number of absolute encoder data bits.

Note: The encoder offset parameter is adjusted in measurement mode

(DRV_OFF).

If the absolute encoder has been declared in assisted offset, this parameter is not taken into account. The assisted offset procedure is used to avoid having to make any calculations. However, after reading READ_PARAM, SAVE_PARAM or saving parameters, the encoder offset value reflects the offset used by the channel.

Example If the absolute encoder shows a measurement of 100 mm for position 0 and the resolution is 2 microms, the offset value is:

-100000 / 2 = -50000 encoder points.

Adjustment procedure

Perform the following operations on the TSX CAY Debug screen:

Step

Action

Select Manual mode

Create a manual reference point if the encoder is of incremental type

Choose Theoretical distance as the value to run which corresponds to the greatest possible range of movement: position 1 and enter this value into the

Param field (e.g. 300,000 microm)

Give the Inc- or Inc+ command depending on the direction of movement

Measure, with a sufficiently precise external device, the distance actually covered by the moving part (Observed distance)

Change to measurement mode DRV_OFF

Adjustment

Carry out the following operations from the Adjustment screen:

Step

Action

Press the Correction button, which displays the following dialog box :

Observed distance:

OK Cancel

0 l l

Enter the distance to be covered in the Theoretical distance field. For example: 300,000 microm.

Enter the distance done in the Observed distance field. For example:

293,000 microm

Press OK to activate the automatic resolution calculations. The new Distance and Nbre points values are then re-calculated.

Repeat steps 2, 3, 4 and 5. If the distance measured reveals a deviation below requirements, then adjustment is finished. If this is not the case, carry out a new correction (steps 7 and 8).

Note: If you modify the Initial resolution and VMAX parameter values after adjusting the resolution, it is mandatory to resume the adjustment.

In general, modifying any configuration in offline mode means that the resolution must be re-adjusted in online mode.

Description of

Gain Parameters

This table describes the gain parameters:

Parameter

Gain 1 and Gain 2

Threshold of 1 to 2

Significance

Position loop gains (from 50 to 12,000 1/100 s).

By default: Gain 1 = Gain 2 = 1000 1/100 s

The axis control module uses the 2 gain values: l Gain 1: gain value for low operating speeds. This value is used to obtain very slight position deviations.

l Gain 2: gain value for high operating speeds. This value is used to avoid overshoot and instability.

Gain switching threshold (from 20 to 500 per thousand VMAX)

By default: Gain threshold = 500 per thousand VMAX

Position gain The applied position gain is as follows: l l l

If the current speed > = 3 x Threshold / 2, Gain = Gain 2

If 3 x Threshold / 2 > current speed> = Threshold / 2, Gain = (Gain 1 + Gain 2) / 2

If current speed < Threshold / 1, Gain = Gain 2

This drawing shows gain value according to current speed:

Gain

Speed

Proportional

Gain Coefficient

The axis control module calculates the KP proportional gain coefficient on the basis of the Gain adjustment: KP = C x UMAX x Gain

C = constant, and UMAX = variable speed controller setpoint value in order to obtain the speed VMAX (UMAX < 9 V).

Note: In general, Gain 1 = Gain 2.

Adjustment

Description of

Feed Forward

Parameter

This table shows the feed forward parameter:

Parameter

Feed forward

Significance

Feed forward adjustment coefficient (from 0 to 100%).

By default: Feed forward = 10%

The feed forward coefficient is expressed as a percentage. 100% corresponds to the value, which can completely absorb the position error at constant speed for a variable speed controller without continuous error.

When the feed forward coefficient rises, the position error is reduced. However this results in a risk of overrun, including when approaching the breakpoint. A compromise must therefore be found.

Note: In certain cases, the position error crosses a minimum threshold with a change of sign if the feed forward rises.

Description of

Offset Parameter

This table describes the offset parameter:

Parameter

Offset

Significance

Offset adds to the analog output value calculated by the loop (from –

250 mV to +250 mV).

By default: Offset = 0 mV

Adjusting Loop Control Parameters

Introduction Adjusting the controls requires you to enter particular values for certain operating parameters. The values of the other parameters are defined by the application.

To do this, enter these parameters in the adjustment screens, then confirm in order to send the parameters to the axis control module.

Initial Operation This operation involves entering a forced reference point in Manual mode.

l l

The forced reference point allows there to be a referenced axis from start-up, and thus enables the following checks and functions: software limits, clearing outside software limits.

Note: Operation will only be correct if the direction of the moving part is the same as that of the measurement.

Forced

Reference Point

Procedure

To create a forced reference point, carry out the following operations:

Step

Action

Select the TSX CAY Debug screen

Select Manual mode

Acknowledge faults using the Ack. command

Using an external device, measure the position of the moving part in relation to the reference point cam (approximate measurement)

Create a forced reference point: l enter the measured value with its sign as the source position value in the

Param field, l select the Forced reference point command.

203

Adjustment

Adjusting High-

Speed Gain

To determine the value of the Gain 2 parameter, carry out the following operations:

It is assumed that the moving part has an inertia equal to the maximum value encountered in the application.

Step

Action

Make movements from position 1 to position 2 and vice versa. To do this: l l l select an average speed, using the speed parameter in manual mode, enter the movement value in the Param field, activate the Inc+ (position 1), then Inc- (position 2) commands in succession,

Check following error when the moving part is at constant speed.

Adjust Gain 2 for an acceptable deviation, while maintaining an appropriate stability (otherwise, check the machine definition). For each new Gain 2 value entered, use the same value for Gain 1 and transfer by confirming at the adjustment screen

Adjusting Low-

Speed Gain

Execute the following operations to determine the Gain 1 parameter value. This adjustment must be carried out for frictional machines, otherwise retain the value of

Gain 2 for the Gain 1 parameter. To obtain a larger gain at low speed, set Gain 1 higher than Gain 2 then transfer the values by confirming at the adjustment screen:

Step

Action l l

Make movements from position 1 to position 2 and vice versa. To do this: l select a very low movement speed: by choosing a low CMV coefficient value, enter a low movement value in the Param field, activate the Inc+ (position 1), then Inc- (position 2) commands in succession,

Check following error when the moving part is stationary

Adjust Gain 1 for an acceptable deviation, while maintaining an appropriate stability. For each new Gain 1 value entered, transfer by confirming at the adjustment screen

Adjusting the

Gain Threshold

The gain threshold must be set at a speed which overcomes friction.

204

TLX DS 57 PL7xx

Adjusting Feed

Forward Gain

Adjustment

Perform the following to determine speed feed forward gain:

Step

Action

Make movements at speed VMAX from position 1 to position 2 and vice versa.

To do this: l l l select a high movement speed: while choosing a high CMV coefficient value, enter a movement value in the Param field, activate the Inc+ (position 1), then Inc- (position 2) commands in succession,

Adjust the feed forward for the value and sign of the error required

Note: If the overshoot is too large, you may wish to reduce feed forwardslightly.

Offset

Adjustment

Adjusting

Integral Action

When the moving part is stationary, select loop control disabled mode DIRDRIVE.

Adjust the offset in the window from –250 mV to +250 mV to cancel out any slipping of the moving part.

For a TSX CAY 22/42 or TSX CAY 33 module, integral action is used to compensate for the different offsets in the string (e.g. module, drive, motor, mechanical equipment) as well as drift. The Ti position loop parameter is used to achieve this compensation.

The gain is only active when the axis is theoretically stationary (theoretical speed is zero, following error absorption phase). Is it active in automatic and manual modes in the absence of a blocking fault on the axis (AX_OK=1 ). It is inactive in the automatic modes EXT_CMD and SLAVE.

The principle is to add an additional continuous action, which is updated during stop phases.

The integral action is expressed in ms, in the interval [100, 5000] ms. By default the value 0 indicates that there is no integral action.

To design a simple or complex button box, commands and elementary information are available in the form of bits, command and status words and bits.

The following example shows how to perform a movement in manual mode for movement view type JOG+, and to change the CMV coefficient for speed modulation, on a CCX 17 human-machine interface terminal.

Both the command and the coefficient for speed modification can be carried out from the application-specific debug screen, or from the CCX 17 terminal.

In the following contact network, %M200 corresponds to the state of the CCX17 terminal button which activates the JOG+ command.

Diagnostics and maintenance

Fault and command executability monitoring

Fault monitoring There are several ways of detecting a possible fault: l l

LEDs on the module front panel.

Diagnostic screens which can be accessed by the DIAG key in online mode from all the application-specific axis control module screens.

l l

Debug screens.

Fault bits and status words

Movement commands l l l l l l

The following conditions must be fulfilled in order to execute movement commands

( in automatic or manual mode):

The axis is configured and is without a blocking fault.

The ENABLE variable speed controller enabling command is active (%Qxy.i.9 bit is in position 1) and the STOP command is inactive. l

Automatic or manual mode is selected.

For commands in absolute position, the position is: l l between SL_MIN and SL_MAX ranges for a limited axis, between values of 0 and modulo –1 for an unlimited axis.

For commands on a relative position, the target calculated from the current relative position is between the limits SL_MIN and SL_MAX.

The axes are referenced, except for the reference point commands.

The SMOVE function parameter F is equal to VMAX.

Modifying the

CMV parameter

If modifying a CMV speed modulation parameter implies a resulting speed greater than VMAX, this speed is limited to VMAX.

Sequence control

If the Sequence control option has not been selected in the configuration, a nonstop movement followed by no sequencing command will continue as far as a soft stop.

Diagnostics and maintenance

Diagnostics help

Introduction

What to do in situations

Situations may arise which you have to resolve. The following procedure is designed to help diagnose these situations, and indicates the path to follow.

New parameters not taken into account

Problem

Diagnostics

What to do

The TSX CAY module does not seem to have registered the new parameters written by WRITE_PARAM.

Program a READ_PARAM instruction into the application to find out the values actually being used by the module.

A WRITE_PARAM is triggered and ignored while exchanging other adjustment parameters

Test the %Mwxy.i.0.X2 bit before exchanging any adjustment parameters.

Event processing

Problem

Diagnostics

What to do

The event processing associated with the axis control channel has not been executed.

l l l

Check that the whole event feedback string has been confirmed: l Event number declared in the configuration is identical to the one in event processing.

Origin of event unmasked (M code from the SMOVE command).

Events authorized at system level (%S38 = 1.

Unmasked events at system level (UNMASKEVT()).

Refer to event usage.

Lost adjustments

Problem

Diagnostics

What to do

Adjustments have been lost.

A cold restart can cause current adjustments that have been carried out via a screen or by a WRITE_PARAM instruction to be lost.

Save current adjustments by using the Utilities

→

Save parameters command, or by using the SAVE_PARAM instruction.

Inconsistent status words

Problem

Diagnostics

What to do

%Mwxy.i.1 and %Mwxy.i.2 status words are inconsistent with the status of the axis control channel.

These words are only updated through an explicit READ_STS request.

Program a READ_STS instruction into the application.

TLX DS 57 PL7xx

247

Diagnostics and maintenance

Encoder supply fault

Problem

Diagnostics

What to do

The encoder supply fault persists while the encoder is properly supplied and the current value is changing.

The encoder supply return signal has not been wired correctly.

Check the encoder connections.

Ineffective commands

Problem

Diagnostics

What to do

The debugging screen commands are ineffective.

The application or the task is in STOP mode.

Change the application or the task to RUN mode.

Non-modifiable commands

Problem

Diagnostics

What to do

Certain debugging screen commands cannot be modified.

These bits are written by the application.

Use bit forcing (for %Qxy.i.r type objects) or re-do the application to avoid systematic writing of these bits (modification on transition and not on status).

Character entry not possible

Problem

Diagnostics

What to do

It is not possible to enter more than 3 characters into the digital fields in the adjustment and configuration screens.

The thousands separator has not been selected in the Windows configuration panel.

In the Windows configuration panel, select the International icon in the

Number format field.

Activate the Modify command and choose a thousands separator.

Introduction to Interpolation

General Information on the Interpolating Function

At a Glance The interpolating function is available with a TSX CAY 33 module, which is used to carry out linear interpolation between 2 or 3 axes.

TSX CAY 33

XMOVE

This module consists of 3 physical channels associated with X, Y and Z axes, and a logic channel (channel 3) dedicated to interpolation.

Before implementing an application for interpolated axes, each of the axes must be set independently. Interpolation can then be carried out between 2 axes (0 and 1) on the (X, Y) plane or between 3 axes (0, 1 and 2) in the (X, Y, Z) space.

For interpolating 2 axes, the third axis (axis 2) can be used and an independent axis.

TSX CAY 33 module does not offer circular interpolation. However, to get from point

A to point B following a circular trajectory, it is possible to approximate this type of trajectory by using a succession of straight segments.

273

TLX DS 57 PL7xx

Introduction to Interpolation

Configuring

Interpolation

Interpolator

Channel

Programming

Movements command

The number of interpolated axes may be set in the interpolator configuration

(channel 3), after channels 0 to 2 have been configured as independent axes.

If 2-D is specified, interpolation is implicitly declared on the XY plane ( with X: 0 axis and Y: 1 axis). Channel 2 may be used as an independent axis.

If 3-D is specified, interpolation is implicitly declared in the XYZ space and/or on the planes which make up XY, YZ or XZ space (where X: 0 axis, Y : 1 axis and Z: 2 axis).

Configuring the 2 or 3 independent axes that you would like to interpolate is necessary in order to access interpolator configuration.

The XMOVE command is used to program interpolated movements. This command is an addition to SMOVE axes, not a substitute.

Axes are only interpolated during the execution of an XMOVE command. Outside of

XMOVE commands, they can be commanded independently by an SMOVE command.

Interpolated axes movement command

Independent axes movement command

274

TLX DS 57 PL7xx

Speed

Introduction to Interpolation

The speed which you specify in the XMOVE command is the desired speed in the direction of movement. The movement speed of each axis is calculated by means of a projection.

Example for a 2 axis system

The moving part must move from point A (X

, Y

) to point B (X

, Y

) at speed F, which projects onto X and Y respectively in F

and F

Using value F, which is provided in the XMOVE instruction, the interpolator calculates projections according to the formulae:

= F

× (

– X

) ⁄ ( ∆

)

= F

× (

– Y

) ⁄ ( ∆

) with

∆

X =

[ (

– X

) 2

(

– Y

) 2 ]

TLX DS 57 PL7xx

275

Introduction to Interpolation

Maximum Speed Speed F is limited to a maximum speed which depends on: l l the maximum speeds of each axis affected by the movement, the contribution of each axis within the movement.

Example:

Acceleration

FX # 0

F < VMAX_axeX

- X

| = |Y

- Y

= F

F < (F

+ F

)

1/2

For each XMOVE movement, the duration of the acceleration phase depends on: l l l the speed variations to be performed, the Tacc parameters for the axes affected by the movement, the contribution of X, Y and Z axes.

The resulting calculated acceleration is the fastest that the movement can happen, while respecting the constraints of the different axes (the most constraining axis determines the duration of the acceleration).

The acceleration rule is defined by the SLOPE parameter from channel 3. This imposes a common rule over all axes during an XMOVE independently of SLOPE parameter value for X, Y and Z axes.

Preliminaries

Accessing interpolation parametering

Channel 3 is dedicated to interpolation. Before configuring channel 3, the independent channels affected by the interpolated movement must be configured.

To access interpolation parametering, select the TSX CAY 33 module and confirm

(double-click on the picture of the module).

Step

Description

Choose channel 3 from the Choose axis field

Select the Interpolation function from the Function field

Select the task associated with channel 3: MAST or FAST.

The task selected (MAST or FAST) must be the same for channel 3 as for the other channels affected by the interpolation. If a task is different, a dialog box appears during confirmation to indicate the channel number which does not have the same task as channel 3.

Note: The interpolated channel axes must be a limited type. It is not possible to interpolate infinite axes.

If an infinite axis has been selected, a dialog box will appear while confirming to indicate that the channel number is not a limited axis type.

X, Y, Z defines the coordinates for reach position for channels 0, 1 and 2, or for the position which the moving part is heading for (in the case of a non-stop movement).

This position can be: immediate, coded in pairs of %MDi internal words or %KDi internal constants (these words can be indexed).

This value is expressed as a unit defined by the Length Unit configuration parameter for each axis.

Moving part movement speed

F defines the speed of the moving object (or the movement speed required for the direction of movement to be carried out). This speed can be: l l immediate, coded in a double %MDi internal word or %KDi internal constant (this word can be indexed).

Example for a 2 axis system

Using speed F, the interpolator calculates FX and FY projections which are used to guide the 2 axes on their trajectory.

The actual movement speed is equal to required speed F multiplied by the CMV speed modulation coefficient, whose value can be adjusted in the interval [0.001,

2.000].

Description of elementary movements

Introduction

Types of movement

2 types of movement category can be programmed: l l movements on a position ( instruction codes 01 and 09), movements until event detection (instruction code 10).

During the program and movements, the reach positions, speed and interpolating plane / space can all be defined. The acceleration parameters are defined by adjusting them.

Types of movement are as follows: l Absolute in relation to the machine homing point (code 90).

Example : non-stop movement on the XY plane, up to position (50000, 10000), up to a speed of 1000.

XMOVE %CH102.3(1,90,01,0,50000,10000,0,1000,0)

Relative in relation to current position (code 91).

Example : non-stop movement on the XY plane, l an increment (+2000, -1000) in relation to the current position, up to a speed of 500.

XMOVE %CH102.3(1,91,01,0,1,2000,-1000,0,500,0)

Relative in relation to PREF latched position (code 98)

Example : non-stop movement on the XY plane, an increment (+2000, +5000) in relation to the previously latched position, up to a speed of 800.

Event

The G10 instruction moves axes until detection of an event or up to the position specified in the absence of an event.

The awaited event can be: l A rising or falling edge (according to selections made while configuring) on one of the reflex inputs for one of the interpolated axes.

l A command from the application which can be: l a rising edge EVT_EXT bit for one of the axes, l a rising edge EVT_EXT interpolator bit,

Nibble 1 for parameter M is used to specify the axis (or axes) for the awaited event:

X Axis – Reflex input or EVT_EXT (%Qxy.0.10) bit

Y Axis – Reflex input or EVT_EXT (%Qxy.1.10) bit

Awaited event

This instruction is used to wait for an event with a Time Out (in ms), defined in the F parameter. If an event does not appear within the Time Out period, the await command is then deactivated. If F parameter is defined at 0, the wait is without a time limit.

The awaited event can be: l l a change in the status of a reflex input for one of the interpolated axes, a command from the application.

Nibble 1 for parameter M is used to set the axis (or axes) for the awaited event:

Event task

X Axis – Reflex input or EXT_EVT (%Qxy.0.10) bit

Y Axis – Reflex input or EXT_EVT (%Qxy.1.10) bit

Z Axis – Reflex input or EXT_EVT (%Qxy.2.10) bit

Interpolator - EXT_EVT (%Qxy.3.10) bit

The G05 instruction can activate an event task on detection of an event, if nibble 3 of parameter M is set to 1.

TO_G05 (Ixy.i.49) bit is set to 1 when the Time Out period has expired without an event being detected, providing task event activation has been requested. For example, wait with a Time Out period of 1.5 s and with task event activation:

There is no fault: bit GP_OK = 1.

Axes affected by the movement are in automatic mode, where bits DONE = 1 and ENABLE = 1. These axes are also stopped.

Sequencing movement commands

Producing a trajectory

TSX CAY 33 module does not offer circular interpolation. However it is possible to approximate any trajectory by a succession of segments.

Example of a 2 axis system trajectory:

An XMOVE command corresponds to each elementary segment of the trajectory.

Note: Each elementary XMOVE command must only be performed once. It is therefore necessary that the program to be executed is either l l in Grafcet: in one step, on activation or deactivation of this step, in structured text or contact language : on the rising edge of a bit.

A report on function execution is provided by the module using the NEXT and

DONE bits.

TLX DS 57 PL7 xx

299

Programming interpolation

Buffer memory TSX CAY 33 possess a mechanism which is used to sequence movement commands.

The interpolator has a buffer memory (or stack) which can receive 3 movement commands in addition to what it is in the process of executing. Thus when a movement in progress has finished, it proceeds directly to the first command present in the buffer memory.

When the stack is empty and a G1 type movement has been requested, it does not start if the module has not received the following movement.

l l

Sequencing between 2 movement commands is as follows : instantaneously if the first movement is non-stop, as soon as the moving part is in the target window, or after time delay TSTOP has expired (which is defined in the stop control on parameter adjustment screen) if the first movement is with a stop.

For the sequencing to be instantaneous, the instruction execution time must be more than the duration of the task in which the XMOVE commands have been programmed.

l l

Refusal of an XMOVE command is indicated by the following data:

CMD_NOK bit (%Ixy.3.6) which indicates a refusal,

CMD_FLT (%MWxy.3.7) word which indicates the cause of the refusal. Reading this word requires a READ_STS instruction.

The following XMOVE movements cause command refusal (CMD_NOK), stop the l l l moving part and reset the buffer memory to zero. sequencing a G05 or G92 after a G01, absence of an instruction after a G01, receiving a command with a SPACE parameter affecting an axis which is not stationary, while it is not being affected by a previous XMOVE command (this is where an XMOVE is with an axis whose last movement was an SMOVE G1).

Bits associated with a sequencing mechanism

The following bits are associated with the sequencing mechanism:

Bit

NEXT (%Ixy.3.0)

DONE (%Ixy.3.1)

Description

Indicates to the program application that channel 3 is ready to receive the following XMOVE command.

Indicates the command in progress has finished being executed and there are no new commands in the buffer memory.

TH_PNT (%Ixy.3.10) Indicates that the setpoint value has been reached on the axes affected by the XMOVE.

AT_PNT (%Ixy.3.9) At the end of a movement with a stop, this indicates that for all the axes affected by the movement the moving part is in the target window.

Note: The NEXT bit or the DONE bit must always be tested before executing an

XMOVE command. A new command must only be sent to the module if the buffer memory associated with the axis to be guided is not full.

The SYNC_N_RUN word (%Ixy.3.8) periodically provides the number of the step in progress, in order to carry out movement sequencing.

Concurrent XMOVE and SMOVE functions

Introduction

Example

It is possible to combine movement instructions for a single axis (SMOVE) with movement instructions for several axes (XMOVE) within the program. This can be used to alternate interpolated movements with non-interpolated movements.

The program must refer to objects for the axis concerned before sending an

SMOVE, and must also refer to objects for channel 3 before sending an XMOVE.

Independent X and Y axis movement followed by an interpolated movement :

(X, Y) Plane

An interpolated axis movement prevents any SMOVE guidance relating to that axis

: a running XMOVE forces NEXT and DONE bits to 0 for the axes concerned.

In addition, the IN_INTERPO (%Ixy.i.32) bit for any moving axis affected by an

XMOVE is set at 1. This information, which can be accessed from the application, is designed to help with programming and monitoring.

304

TLX DS 57 PL7 xx

Programming interpolation

Interpolator channel automatic mode

Introduction The Automatic mode is the active mode for interpolated axes. Interpolated movements can only be carried out with this mode.

Automatic mode is mainly used to send a movement command (code G) via an

XMOVE function. This command is designed to perform an interpolated movement by momentarily creating a link between several axes.

Channel 3 in automatic mode

Channel 3 in automatic mode does not modify the current mode, nor 2 (or 3) module axis commands in progress. In this way movements (or debugging) which are carried out independently axis by axis in manual, loop disabled control and automatic modes, are always performed via the positioning function for each axis in the module.

The actual engagement of automatic mode is indicated by the IN_AUTO (%Ixy.3.23) bit.

Commands in automatic mode

In automatic mode, the following commands are used to act on the XMOVE function: l CMV : speed modulation coefficient. This coefficient affects the current tangent speed setpoint in a ratio of 1/1000 to 2000/1000 (%Qwxy.3.1) l CMV = 0 : Feed hold command which stops the moving part, while ensuring that upon the resume movement command (CMV #0), the programmed trajectory is followed. Feed holdstatus is indicated by theIM_PAUSEbit (%Ixy.3.34).

l Pause : Pause command which is used to suspend XMOVE movement sequence. The pause is only active when the moving part is stationary. This is indicated by the ON_PAUSEbit (%Ixy.3.33).

l MOD_STEP (%Qxy.3.19) : is used to execute a movement sequence by stopping after each elementary instruction. Status is indicated by the IN_STEPbit

(%Ixy.3.39).

NEXT_STEPbit (%Qxy.3.22) is used to execute the next step.

l EXT_EVT (%Qxy.3.10) : is used to terminate a G05 or a G10.

The automatic mode can also access the following 2 commands which can be active during or outside of an XMOVE: l STOP : is a stopping order for the different axes which make up the interpolation

(according to the role of the STOP command that has been defined in the l configuration).

ACK_DEF : a rising edge acknowledges faults for all axes.

Event processing with interpolated axes

Introduction Channel 3 on a TSX CAY 33 module can activate an event task. To do this, the functionality must have been enabled on the configuration screen by associating an event processing number to the channel.

Activating an event task

An event task is activated by the appearance of an event expected by G10 and G05 commands. For this to happen, nibble 3 from XMOVE function parameter M associated with the instruction must be equal to 1.

Usable variables for the event task l l

If several event sources are chosen, the following bits are used to determine the source trigger for event processing: l l

EVT_G1 (%Ixy.3.50) : event during instruction G10,

EVT_G05 (%Ixy.3.48) : event during instruction G05, l TO_G05 (%Ixy.3.49) : G05 timer expired

OVR_EVT bit (%Ixy.3.46) is used to detect a delay in event sending or an event loss.

Note: The words and bits described above are the only ones which are refreshed during execution of a task event. They are only updated in the PLC if the task event has been activated.

Event masking PL7 language offers 2 ways to mask events: l Instruction for global event masking : MASKEVT (UNMASKEVT is used for unmasking): l Bit %S38 = 0 (global event inhibition). %S38 bit is normally at 1.

Fault management

Introduction Fault monitoring is essential for axis command tasks, due to the inherent risks posed by active moving parts.

The moving part carries out checks internally and automatically.

Fault monitoring for interpolated axes

TSX CAY 33 channel 3 does not have a specific fault.

Fault information indicated by this channel is the logic OR of faults on axes configured in the interpolated movement (channel 0 and 1 faults in the case of 2 axis interpolation; channel 0, 1 and 2 faults in the case of 3 axis interpolation).

Fault information Fault information is as follows:

Levels of severity

Fault programming

Fault indicating

Faults are classed in 2 levels of severity: l Critical or blocking faults which cause the moving part to stop. The following processes then occur: l l the fault is indicated, the moving part slows down until analog output is zero, l deactivation of the speed drive enable relay, l clearing of all memorized commands, l wait for acknowledgement.

The fault must have disappeared and been acknowledged before the application can be re-started.

l Non-critical faults which give rise to fault indication without stopping the moving part. The PL7 must be programmed with what action to take in the event of this type of fault.

The fault indication disappears when the fault itself has disappeared and been acknowledged.

Faults can be viewed, corrected, and acknowledged from the debugging screen.

However it can be useful to be able to guide the moving part and correct faults from a console during operation. For this purpose, all the information and commands necessary are available within the application.

l l

The module supports a wide range of information in the form of bits and status words, all accessible through the PL7 program. These bits are used to process faults in hierarchical order : to act on the main program, to simply indicate the fault.

Note: With a blocking fault, it is advised to stop the changing sequential processing which is associated with the axes, and correct the fault. Correcting the fault must be followed by a fault acknowledgement.

Fault acknowledgeme nt

When a fault appears on one of the interpolated axes: l The axis fault bits: AX_FLT (%Ixy.i.2), HD_ERR (%Ixy.i.4), AX_ERR (%Ixy.i.5) and STATUS (%MWxy.i.3:Xj), as well as the faults bits associated with interpolating: AX_FLT (%Ixy.3.2), HD_ERR (%Ixy.3.4), AX_ERR (%Ixy.3.5) and

STATUS (%MWxy.3.3:Xj) are set to 1.

l If the fault is a blocking fault, the AX_OK bit is set to 0.

When the fault disappears, all fault bits retain their status. Faults are stored until they have been acknowledged through setting to 1 of the ACK_DEF bit (%Qxy.i.8, where i = channel number which has the fault) or the ACK_DEF interpolation channel bit

(%Qxy.3.8). Setting to 1 of the channel 3 ACK_DEF bit generates acknowledgement for all interpolated axes. Fault acknowledgement must be carried out after the fault has disappeared (except for soft stop faults).

If several faults are detected, the acknowledgement order will only act upon faults which have effectively disappeared. Persisting faults must by acknowledged again after their disappearance.

Note: Channel 3 (interpolator) does not store faults.

Description of command refused faults

Introduction

Command refused

A command refused fault is generated each time a command cannot be executed.

This occurs when a command is not compatible with the axis state, with the mode in progress or where at least one of the parameters is not valid.

These faults are indicated by the Refus Cde LED on the debugging screens. At channel level, the DIAG key can be used to identify the source of the command refused fault. This information can also be accessed through a program with the

CMD_NOK bit (%Ixy.3.6) and the CMD_FLT word (%MWxy.3.7).

Th following table shows the cause, indication and the remedy in the event of a

Command Refused fault.

CMD_NOK (%Ixy.3.6) bit : Movement command refused

CMD_FLT (%MWxy.3.7) word : type of fault detected l l

Least significant byte : movement commands,

Most significant byte : configuration and parameter adjust.

When a new command is received and accepted, acknowledgement is implicit.

Acknowledgement is also possible via the ACK_DEF command

(%Qxy.3.8)

Note: For movement sequences in automatic mode, it is advised to make the execution of each movement conditional upon the completion of the previous movement, and upon the AX_FLT bit (%Ixy.3.2). This will prevent the program moving on to the following command should the present command be refused..

Managing measurement (OFF) mode

Introduction Measurement (OFF) mode is the interpolator passive mode: the X, Y and Z axes are in independent axis state. It is therefore possible to command them in loop control disabled mode (DIRDRIVE) in manual or automatic mode.

No channel 3 command is taken into account in this mode, except for the fault acknowledgement command.

Stopping XMOVE If an XMOVE is in progress, switching to OFF mode will make it stop.

Accessing the parameters

To access the interpolation adjustment parameters, use the Adjust command from the View menu on the TSX CAY 33 module configuration screen. Adjust can also be selected in the module zone in the debugging or configuring screen.

The adjustment screen is used to select the channel to be adjusted, and enables access to current or initial parameters.

Function

Choose channel 3.

This button displays either the current parameters or the initial parameters. This function can also be performed using the F7 key.

Initial parameters

Current parameters

Adjustment parameters

The initial parameters are : l Parameters entered (or defined by default) in the configuration screen in offline mode. These parameters have been confirmed in the configuration, and transferred into the PLC.

l Parameters taken into account during the last reconfiguration in online mode.

Current parameters are those which have been modified and confirmed from the adjustment screen in online mode (or by program via an explicit exchange). These parameters have been replaced by the initial parameters after a cold restart.

Crossing Points

Description of

Speed Delta

Parameters

These 3 parameters (one parameter for each interpolated axis) are used to set:

Adjustment

Speed Delta X

Speed Delta Y

Speed Delta Z

Meaning

Variation of speed allowed on crossing points for each axis. The speed adjustment for the moving part at the crossing point allows the moving part to pass closer to the target point when the defined value is low.

These parameters are expressed as a thousandth of VMAX.

Limits: 0 to 500

Processing

Crossing Points

In a linear interpolation, when a succession of non-stop G01 type movements are performed, the concept of crossing points becomes clear.

For example, let us assume that an ABC trajectory is required.

A specified speed maintained up to B on the AB segment causes an overshoot

(figure 1). If the speed is reduced before arriving at B, then the real trajectory remains inside the ABC angle (figure 2).

Figure 1 Figure 2

316

TLX DS 57 PL7 xx

Overshooting

Adjustment

How to Avoid Overshooting: l The natural delay (following deviation) of each axis is used. To do this, it is l advised to moderate the feed forward gain adjustmentKV during interpolated movements.

In a sequence (G01, X1, Y1, Z1, F1) followed by another sequence (G01, X2, Y2,

Z2, F2), if F2 is smaller than F1, the speed trajectory is modified so that the desired speed is equal to F2 at the break point.

The following figure illustrates the modification of the speed trajectory so F2 speed is reached on the break point:

Break point

Feed X1, Y1, Z1 X2, Y2, Z2 l Role of the parameter: DELTASPEEDPATH

The module introduces a mechanism, which can reduce the speed at the point of crossing, according to the requested "Delta speed" (axial Delta speed X, Y or Z).

The function is implemented from the point at which the VMAX can be adjusted.

The function is active when:

∆

(of an axe)

> VMAX * DELTASPEEDPATH/1000

Note: The smaller the DELTASPEEDPATH parameter, the closer the point.

Principles of debugging an interpolated axis control program

Introduction

Reminder of capabilities offered by PL7

Debugging screen

Axis control, integrated into PL7 programming, uses PL7 debugging functions.

Refer to principle for debugging an independent axis (See Debugging principles,

p. 222).

The task-specific debugging screen, unique to TSX CAY 33 module channel 3, allows access to all the information and commands required for debugging interpolation.

The program and moving part control zone offers 2 possible screens according to the operating mode selected via the mode switch: Measurement (OFF) or Automatic

(AUTO).

Introduction to the "Cutting On the Fly" Utility

At a Glance The main objective of this function is to be able to respond to applications consisting of: l l a "conveyor belt" axis, which transports a product, a "tool carrier" cart axis, which carries out return travel between a rest point and a "working" point, and which synchronizes position and speed with the belt.

The application therefore requires: l an axis channel, which acquires the advanced speed and position of a product to be cut l an axis channel which controls the movement of the cutting tool support and command with a discrete output.

345

TLX DS 57 PL7xx

Introduction to the "Cutting On the Fly" Utility

Principle of the

"Cutting On the

Fly" Utility

The table below introduces the different stages of a cutting cycle.

Step

Action

The cart is in waiting position at the point of rest.

Note:The cutting value is a reading relative to the last cut made. This position is called "source control"

The card calculates the source control corresponding to the next cut and checks that the cut is possible.

When the product feed is equal to the length to be cut less a synchronization distance (in order to be synchronized at the point of synchronization), the cart accelerates and synchronizes with the controlling axis while aiming for the source control.

When the chariot is synchronized, it remains attached in position for the whole journey.

When crossing the tool descent point, an output commands the cutting action.

Upon indication that the cut (on a sensor input or position) is finished, the tool is rechucked.

Upon indication that the synchro (on a sensor input or position) is finished, the cart exits slave mode and stops as quickly as possible.

Upon indication of a theoretical stop, the cart returns to the rest position and slowly restarts the cycle.

Solution

Adapted to the

TSX CAY 22 V2.0

Module

Implementation of this utility with a TSX CAY 22 module V2.0 requires the definition of: l channel 0 as a control axis for the acquisition of the position measurement for the product to be cut (belt, conveyor). This is an infinite axis, which continually l advances in the positive direction.

Channel 1 as an axis for the cutting tool support cart. This is a limited linear axis, whose behavior is guided by the controlling axis feed. l l l

Channel 1 supports: the static command output for the cutting tool, the end of cutting sensor input (if necessary in the application), the end of synchro sensor input (if necessary in the application).

Note: If necessary, channel 0 can support the event cutting sensor input.

If the utility is not used, the module is totally compatible with preceding versions.

Description

If checked, the "cutting on the fly" utility is activated

Indicates that the cutting angle between the belt feed axis and the tool feed axis can vary dynamically.

The value of the %MDxy.0.65 and %MDxy.0.67 words allows this variation by application.

Cart speed = infinite axis speed x K0 x movement ratio using K0 =

(%MDxy.0.65 / %MDxy.0.67)

Comment: when this parameter is not checked, only the Movement ratio values are used

The cart speed then becomes: Infinite axis speed x Movement ratio

Indicates the speed movement ratio between the belt and cart.

Limits [1/sin80, 1/sin10];1, with 1/sin80 = 1.015426 and 1/sin10 = 5.758770.

The numerator and denominator should be whole numbers between 1 and

10.10

Indicates that the K0 factor is used when calculating the length of the product to be cut.

Length produced = length of belt movement / K0 with K0 = (%MDxy.0.65 / %MDxy.0.67).

Comment: when this parameter is not checked, the length of the product to be cut is equal to that of the belt.

Indicates that the tool deactivation time is ordered by the EXT_EVT output

(%Qxy.1.10) on channel 1. The tool is rechucked after this time.

Comment: when this parameter is not checked, it indicates that the tool deactivation time is triggered when a position crosses. The tool is rechucked after this time.

Indicates that the length to be cut can be determined by an EVENT input on channel 0. The cut reading is determined by the belt position at the event rather than the cutting distance on the event.

Indicates that the module should use the parameter Acce max for configuration when stopping after cutting.

Indicates that the end of synchronization time is ordered by the RECAL output on channel 1. Effective desynchronization is performed after this time.

Suspension occurs between the re-calibration and cutting on the fly utilities.

Comment: when this parameter is not checked, it indicates that the synchronization end time is triggered by a position. Effective desynchronization will be performed after this time.

All these parameters are deactivated by default. All combinations are possible.

Preliminaries

Principle

All G codes already present on the TSX CAY22 V1.x are recognized and applied so that they are defined on channel 1 when the "Cutting on the fly" utility is activated.

In particular, they allow homing and initial positioning at the point of synchronization before beginning a cutting cycle.

The MANU, DRV_OFF, DIRDRIVE modes are not affected or modified when the cutting on-the-fly utility is activated on channel 1.

Programming the "Cutting On the Fly" Utility: SMOVE function

Preliminaries

Detailed

Description

This topic contains a description of the SMOVE function parameters with code 22.

The SMOVE function should be used to program a cutting on-the-fly movement with the following syntax: SMOVE %Chxy.1(N,Gp,22,Dist,Vit,M)

Parameter Description

%Chxy.1

Channel 1 address

Dist

Vit

Movement Number

Preparatory code. Possible values are: l l

90 : Normal cut

98 : Cut on event

Specific instruction code for cutting on the fly

Cutting length

Speed for return to rest point

Initialization of cut counter l l l l

Where:

(Dist/K0) < modulo/2

(Dist/K0) * K0 * Movement ratio > (PointSynchro - PointRepos)

Vit <= Vmax l

M = 0 or 16#0100. If M = 16#0100, the counter is then initialized at 0 then incremented if the cut is performed

The movement programmed can only be executed under the following conditions:

Axis conditions

Axis 0 Axis 1

Channel 0 should be configured as an infinite machine. It is advisable to enter the maximum value authorized into the modulo, so that the cutting length of the product is not limited.

The channel 1 cutting on the fly utility must be configured

Channel 0 should not have a blocking fault The operating mode should be set to automatic

It is essential that the numerator product for the Movement ratio with the K0 numerator be less than 2

Axis 1 should be referenced

TLX DS 57 PL7xx

355

Programming the "Cutting On the Fly" Utility

It is essential that the denominator product for the Movement ratio with the K0 denominator be less than 2

The drive should be Enable

The K0 ratio should be between 0.01 and 5 The cart should have come to rest. The preceding movement should be a G09 or G22 and should have the rest position as a position setpoint.

The distance between the * K0 * Movement ratio synchronization rest point and end point should be more than modulo/2 on channel 0

Code G98: l l

(Cutting distance on evt/K0) < modulo/2

(Cutting distance on evt/K0) * K0 *

Movement ratio > (Synchronization point position - Rest position)

Only the SMOVE with G22 instruction saves the control source point to memory. All other instructions or mode changes erase this memory.

If there is no control source point in the memory upon the next SMOVE with G22 instruction, the new control source point is equal to the conveyor belt position at the point at which the instruction was received plus the length of the Dist cut passed to parameters.

Dynamic

Condition for

Refusing

Command

A command is refused if:

When starting the tool, the module states:

Either the belt speed is too great in relation to the Vmax cart speed, or the synchronization distance is more than the distance between the synchronization point and the rest point.

Warning on

SMOVE with G22

"Value exceeded"

A warning is generated if the module states, when receiving the SMOVE with G22 instruction:

Either that the belt is too close to the control source point to cut, in which case, the module will calculate a new control source, which will allow cutting with the following formula:

New control source point = n * Dist + last control source point, where n is the smallest whole number which allows the cutting cycle to be implemented

Or that the control source point has been exceeded, in which case, the

FAIL_CMD_AUTO_COTE_DEPASSE 0x0042 Warning is given to the PLC at the beginning of the execution of G22.

356

TLX DS 57 PL7xx

Programming the "Cutting On the Fly" Utility

Long Cut on

Event G98

Immediate Cut

A sensor detects the course of the product to be cut. When the event is received, the module memorizes the belt position and calculates the cutting point according to the following formula:

Control source point = Memorized position + Cutting distance on event.

The Dist parameter should have a value more than the cutting length on event so that the event triggers the tool. This forms a security system, if the event does not intervene during the final cutting distance.

Be careful not to disturb the event input on channel 0 when cutting on event.

To perform an immediate cut, the module should be in waiting phase 0 for starting a cart with the SMOVE with G22 instruction and receive a CoupeIm(%Qxy.1.20) rising edge command. The module will calculate the minimum cutting distance for a shorter piece than the one currently being carried out. The cutting position is saved as the control source for the next cut.

If the cart begins to move, the command for an immediate cut is ignored.

Operating Mode After carrying out each cutting instruction, the cut counter (%Iwxy.1.7) is increased.

While executing a G22, it is possible to prepare and send the module the consecutive cutting order at the end of the current cut, which can be identical or different to the current cut.

To halt the cutting operations using the cart at the rest point, it is possible to: l No longer send G22 and allow the current cuts (or those queuing in the module) to be completed l Send a Pause order to allow the current cut to be completed without moving on to the orders queuing in the module l Send a STOP order when the G22 is waiting (%Ixy.1.44)

The Feed hold command (via the CMV command reset) is ineffective.

The CMV alteration is ignored during the SMOVE with G22 command. Only the current CMV value present from the start of the command is taken into account.

A blocking fault on channel 1 stops the cart by exiting the synchronization status axis where it is.

Note: Alterations to your own parameters for the cutting on-the-fly are only adapted when the cart is at the rest point.

Comment: Detailed editing of the SMOVE with G22 instruction is not currently possible.

Tool Output

Operating Mode

In manual mode, this is the strict copy of the AUX_OUT (%Qxy.1.11) output bit.

In automatic mode, it is set by the M parameter for ALL instructions with a G code.

l l

During a G22 code instruction, the status depends upon:

The current position of the cart

The parameters: Tool descent position, Tool rechucking position, Tool deactivation time delay.

l The InhibTool (%Qxy.1.21) command.

Tool descent always takes place on the Tool descent position, without the use of a time delay.

The tool rechucking takes place on a position, after the Tool deactivation time

delay. The position is set either by the Tool rechucking position on the adjustment screen, or by the tool rechucking event if the Tool deactivation on evt. box is checked.

If the Tool deactivation on evt. box is checked, and the expected tool deactivation event does not occur, the Deactivation time delay will be triggered on the way to the Tool rechucking position.

Upon ordering STOP (%Qxy.1.15) the tool rechucks immediately, without any time delay. The axis begins to stop after the Tool deactivation time delay. If this time delay is zero, a value of 4ms is used.

During a SMOVE with G22 command, when the InhibTool (%Qxy.1.21) command is at 1, the auxiliary output is forced to 0. Therefore, the tool remains chucked, regardless of the cart’s position. If the tool was low, it is immediately rechucked, without using any time delay.

If the Tool deactivation on evt. box is checked, the EXT_EVT (%Qxy.1.10) command allows the tool to be rechucked before waiting for the Tool rechucking

position.

Adjusting the "Cutting On the Fly" Utility

Adjustment of K0 parameter

In the configuration screen, if Variable angle has been validated, the K0 parameter can be modified by the application. This parameter shares channel 0 and does not appear in any entry screen. Initialization and modification are performed by using the

%MDxy.0.65, %MDxy.0.67 variables and the WRITE_PARAM %Chxy.0.65 and

WRITE_PARAM %Chxy.0.67 instructions. At the beginning of each cutting cycle, the module stringently checks that the numerator product for the Movement ratio with the K0 numerator and then the denominator product for the Movement ratio with the K0 denominator are both less than 2

. The module also checks that the K0 ratio is between 0.01 and 5.

If this is not the case, an error code is returned.

Adjustment of

DMAX2

Parameter

If the cutting on-the-fly utility is activated and in automatic mode, the DMAX2 parameter becomes the controlling parameter for the following error between the cart and the source control point. This monitoring is only active when the synchronizing phase is ignored by the other phases.

Adjustment of the Acceleration profile Parameter

During a G22 instruction, the synchronizing acceleration phase 1 is always realized using a rectangular acceleration profile, which is independent of the acceleration profile selected on the Adjustment screen.

Adjusting the Ti gain

When the cutting on-the-fly utility is activated, the Ti gain adjusted in the Adjustment screen is active at rest and also during the phase 2 of the moving part synchronization.

Limitations of

Use of "Cutting

On the Fly"

Utility

Adjusting the "Cutting On the Fly" Utility

When using the "Cutting on the fly" utility, channel 1 draws on the position, current speed and captured position information from channel 0. However, it does not manage the channel 0 operating mode. It is therefore the responsibility of the user not to disturb the operation of a cutting on the fly application with the following operations, which can cause disturbances: l l l

Channel 1 reconfiguration

Channel 0 adjustment

Mode change on channel 0 l Disturbance of position measurement on channel 0.

Axis 0 faults do not disturb SMOVE with G22. It is the responsibility of the application to manage the operating modes of axis 1 according to axis 0 when necessary.

The length of the maximum cut is defined by the infinite modulo channel 0 divided by 2. If the tool rechucking is to be performed when EXT_EVT is switching to 1 (tool deactivation on validated event), the module does not manage the TimeOut or associated security.

Independent multi-axis pulse generator with 2 signals offset to 90º. These are produced according to the axis movement and are counted by the module.

Movement law is applied to each axis independently. Axes depart simultaneously, movement speed is a setpoint speed, movement time depends on the distance to be covered, the "axes" do not arrive at the same time; movement through space is ordinary. The aim is to arrive at the arrival address as quickly as possible without constraining the trajectory.

Infinite machines The moving part moves continually between the value 0 and the modulo limit (for example a conveyor belt).
