Bypass Basic Programming Parameters. YASKAWA P7B Drive Bypass

Bypass Basic Programming Parameters

The basic Drive programming for a Bypass unit is different from that of a Drive installation without the Bypass option.

Several Drive parameters have been programmed at the factory to meet the needs of the Bypass logic circuit. See Table 5.1 below, the highlighted parameters are required by the Bypass logic circuit.

Shaded Areas = Parameter settings required by the Bypass logic

The shaded Bypass Parameter Settings in Table 5.1 document Drive parameter settings, required to interface with the Bypass logic circuit, that have been established at the factory and stored in a dedicated location in the memory as “User Initialization” values (think of it as a “back-up file”).

Table 5.1 is also used to document parameters that have been factory set, for convenience, to typical values for fan and pump applications. These parameters may be changed to meet the needs of the specific application.

If additional parameters are set to the specific needs of the application project, and the system operation has been checked and verified, then the “User Initialization” values should be stored in memory again by selecting and entering “1: Set Default” in parameter o2-03.

When there is a need for re-initialization of the “user” parameters (re-setting to the “User Initialization” values) of the Bypass unit, then a “User Initialization” function should be carried out by selecting “1110: User Initialize” in parameter A1-03. This will re-establish the drive set-up required for the Bypass application and any “user” parameter values that have been stored.

The factory parameter settings required to interface with the bypass logic circuit have also been stored in the digital keypad memory. If there is a need for re-initialization (re-setting to a known factory starting point for trouble-shooting purposes) of the Bypass unit, then the “back-up file” in the digital keypad memory can be copied to the drive. In parameter o3-01 select

“2: OP->INV WRITE” to carry out the copy function.

Discussion of Table 5.2 Option-Dependent Bypass Parameter Settings:

Drive Parameter Settings for Various Combinations of Bypass and Options

Notes:

See Appendix D, Communications, for additional information on serial communication.

Hand mode run/stop for Drive and Bypass is always via the front control panel HAND/OFF/AUTO switch.

The HAND/OFF/AUTO switch must be in AUTO position if serial communication is to be used to control the Drive.

For "monitoring only" of Drive parameters and operation, via serial communication, the user needs only to set-up the

H5-0X "Serial Com Setup" parameters. All other parameters may remain as they were factory programmed for the

Bypass unit and options.

Option L, LonWorks serial communication always requires DIP switch S1-1 (terminating resistor) to be ON.

In order to run the Drive and motor with the BYPASS/DRIVE switch in the DRIVE position: the Drive must receive a Run command and a speed command. Parameter b1-01 specifies from where the speed command is received when the Drive is in the

AUTO mode. Switching into the AUTO mode can be done by turning the Hand/Off/Auto selector switch to AUTO while the

Drive is stopped.

IMPORTANT

If a Run command is input to the Drive but no corresponding speed command is input, the Run indicator on the digital operator will turn on and the STOP indicator on the digital operator will blink.

Programming 5 - 11

If you want the Drive to follow the speed command set by the digital operator: Use the HAND mode by turning the

HAND/OFF/AUTO selector switch to HAND. The speed command can then be entered into the U1-01 monitor parameter in the

“-DRIVE-” Menu.

If you want the Drive to follow an AUTO analog speed command: Connect a 0 – 10 VDC speed command signal between terminals A1 and AC or a 4 – 20 mA speed command signal to terminals A2 and AC. Select the AUTO position of the Hand/

Off/Auto switch.

If you want the Drive to receive the speed command from serial communication: Set the parameter indicated in Table 5.2 for the desired serial communication option. Connect the RS-485/422 serial communications cable to terminals R+, R-, S+, and S- on the control I/O terminal block. The HAND/OFF/AUTO selector switch must be in the AUTO position.

Option PCB

To successfully operate the Drive or Bypass and motor remotely, an external run command must be received by the Drive and

Bypass unit. Parameter b1-02 specifies from where the run command for the Drive will be accepted.

This parameter is by default set to “1: Terminals.” This setting is required by the Bypass logic circuit.

To issue a run command from the control panel: Turn the Hand/Off/Auto switch to the HAND position.

To issue a run command from a remote source: Turn the Hand/Off/Auto switch to the AUTO position. A contact closure between terminals TB1-3 and TB1-4 will control the Drive or Bypass start and stop operation.

To issue a run command via serial communication: Set the parameters indicated in Table 5.2 for the desired serial communication option. Connect the RS-485/422 serial communication cable to R+, R-, S+, and S- on the removable terminal block.

“0:Ramp to stop”: When the Run command is removed, the Drive will decelerate the motor to 0 rpm. The rate of deceleration is determined by the active deceleration time. The factory default Decel Time is in parameter C1-02.

Programming 5 - 12

When the output frequency has dropped below the DC Injection Start Frequency in b2-01 (Default = 0.5HZ) DC current will be injected in the motor at a level determined by b2-02 (50% Default). The DC Injection condition will occur for the time specified by b2-04 (0.0 Default), to establish the end point of the ramp. DC injection can be used to insure the motor is at zero rpm prior to the Drive shutting off.

2:DCInj to Stop: When the Run command is removed, the Drive will Baseblock (turn off its output) for the Minimum Baseblock Time (L2-03). Once the Minimum Baseblock Time has expired, the Drive will inject DC current into the motor windings to lock the motor shaft. The stopping time will be reduced as compared to Coast to Stop. The level of DC Injection current is set by parameter b2-02 (50% Default). The DC Injection brake time is determined by the set value in b2-04 and the output frequency at the time the Run command is removed.

Exchange Phase

ExchgPhs, Rev Dsbl

For some applications reverse motor rotation is not applicable and may even cause problems (e.g., air handling units, pumps, etc.). Setting parameter b1-04 to 1 or 3 will cause the Drive to ignore any inputs for reverse operation. Setting parameter b1-04 to either 2 or 3 will change the motor shaft rotation when a Forward Run command is given by exchanging the order of the output phasing.

The factory default setting of parameter b1-04 is “1: Disabled”. When b1-04= “1: Disabled”, reverse operation is prohibited and no exchanging of output phasing occurs.

When the Drive is switched between the Local (Hand) mode (the digital operator) to the Remote (Auto) mode by the Hand/

Off/Auto selector switch, there is the possibility that a Run command is already present (i.e. a contact closure between terminals TB1-3 and TB1-4. Parameter b1-07 determines whether the Drive will:

Ignore the external Run command until it is removed and re-instated (b1-07= “0: Cycle Extern Run”)

OR

Accept the already present Run command and immediately begin acceleration to the commanded speed

(b1-07= “1: Accept Extrn Run”).

IMPORTANT

When switching from local mode to Auto mode when b1-07= “1:Accept Extrn Run” the Drive may start unexpectedly if the Run command is already applied. Be sure all personnel are clear of rotating machinery and electrical connections prior to switching between local mode and Auto mode.

"

b2-01 DC Injection Braking Start Frequency

Setting Range: 0.0 to 10.0 Hz

Factory Default: 0.5 Hz

Parameter b2-01 sets the output frequency where the Drive begins DC Injection during Ramp to stop. in order to lock the rotor of the motor and established the end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at E1-09.

Parameter b2-01 also determines the output frequency that the Drive must be at or below before a Zero Speed condition is considered true. This affects any digital output configured as a Zero Speed signal (H2-0x= “1: Zero Speed”).

"

b2-02 DC Injection Braking Current

Setting Range: 0 to 100%

Factory Default: 50%

The level of DC Injection Braking Current affects the strength of the magnetic field attempting to lock the motor shaft.

Increasing the level of current will increase the amount of heat generated by the motor windings and should only be increased to the level necessary to hold the motor shaft. DC Injection current is set in percentage of Drive rated output current. Drive rated output current is stated on the Drive nameplate.

Programming 5 - 16

"

b2-03 DC Injection Braking Time at Start b2-04 DC Injection Braking Time at Stop

Setting Range: 0.00 to 10.00 Seconds

Factory Default: b2-03 = 5.00 Seconds b2-04 = 0.00 Seconds b2-03 is one of the special parameter settings required by the Bypass logic circuit. See Table 5.1.

The Drive can be programmed to automatically DC Inject for a predetermined amount of time prior to accelerating to speed

(b2-03) and/or at the end of a Ramp to stop (b2-04). Parameter b2-03 can be used to stop a rotating motor prior to attempting acceleration (i.e. a wind milling fan). If DC Injection braking at start or Speed Search is not enabled, attempting to Drive a spinning motor may cause nuisance tripping.

Parameter b2-04 can be used to resist any residual motion of the load after the deceleration has finished.

Parameter b2-04 also serves the function of affecting the length of time DC Injection to stop (b1-03= “2: DC Injection to

Stop”) will occur.

"

b2-09 Motor Pre-Heat Current


Factory Default: 0%

A DC current can be circulated within the motor windings while the motor is stopped. The current will produce heat within the motor and prevent condensation. Parameter b2-09 determines the percentage of Drive rated output current that will be used for the motor pre-heat function. This function can be useful in applications where the motor sits for extended periods of time in humid conditions. Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat Input

(H1-0x= 60). Check with the motor manufacturer to determine the maximum acceptable current level the motor can withstand when stopped. Be sure not to exceed the motor manufacturers recommended level.

Programming 5 - 17

!

b3 Speed Search

The Speed Search function allows the Drive to determine the speed of a motor shaft that is being driven by rotational inertia.

Speed Search will allow the Drive to determine the speed of the already rotating motor and begin to ramp the motor to a set speed without first having to bring it to a complete stop. When a momentary loss of supply power is experienced, the Drive output is turned off. This results in a coasting motor. When power returns, the Drive can determine the speed of the coasting motor and start without requiring it to be brought to minimum speed. Speed Search can be programmed to always be active by setting b3-01 or it can be commanded by remote contact closure by setting a digital input.

There are two forms of Speed Search in the Drive, the speed estimation method and the current detection method.

IMPORTANT

When setting the Drive for remote Speed Search input, via a contact closure, the method of Speed Search is determined by the setting of b3-01. If b3-01= ”0: SpdsrchF Disable” then the remote input will initiate speed estimation method, and if b3-01= ”2: SpdsrchI Disable”, then the remote input will start the current detection method.

Parameters L2-03 and L2-04 also affect the current detection method of Speed Search operation.

Speed Estimation: Method (b3-01= 0 or 1)

The speed estimation method will calculate the speed using measurements of residual motor fields. The speed estimation version is bi-directional and will determine both the motor speed and direction. To enable speed estimation Speed Search at start, set b3-01= “1: SpdsrchF Enable”.

IMPORTANT

If the speed estimation method of Speed Search is to be used, then Auto-tuning must be performed prior to using Speed Search. If the length of cable between the Drive and motor is ever changed after Auto-tuning then Auto-tuning should be performed again.

IMPORTANT

The speed estimation mode cannot be used when there are multiple motors operated by one Drive or the motor is two or more frames smaller than the standard size motor per the Drive capacity.

Current Detection Method (b3-01=2 or 3):

The current detection method starts searching from a predetermined frequency while monitoring the Drive output current to determine when the rotor speed and the Drive output speed (frequency) match.

The current detection version is not bi-directional. To enable current detection Speed Search at start set b3-01= “3: SpdscrhI enable” and program any digital input equal to Speed Search 1 (H1-0x= 61) or Speed Search 2 (H1-0x= 62). Speed Search 1 will start searching from the max. frequency (E1-04) and ramp down to meet the rotor speed. Speed Search 2 will start searching from the set frequency and ramp down to meet the rotor speed.

IMPORTANT

If a UV1 fault occurs when current detection Speed Search is attempted, increase the setting of L2-04.

IMPORTANT

If an OC fault occurs when Speed Search is attempted after power loss recovery, increase the setting of L2-03.

b3-02 Speed Search Deactivation Current

Setting Range: 0 to 200% of Drive rated output current

Factory Default: 120% of Drive rated output current

When using the current detection method of Speed Search, parameter b3-02 sets the current level that will determine when the search is complete and the rotor and output speeds match. When the output frequency is higher than the actual rotor speed the slip causes the current to be high. As the output frequency is lowered, the closer it comes to the rotor speed, the lower the current draw will be. When the output current drops below the level as set in b3-02 (100% = Drive Rated Current) the output frequency stops decreasing and normal operation resumes.

"

b3-03 Speed Search Deceleration Time


Factory Default: 2.0 Seconds

Parameter b3-03 sets the deceleration ramp used by the current detection method of Speed Search when searching for the motor’s rotor speed. Even if Speed Search 2 is selected, for Speed Search at start, the time entered into b3-03 will be the time to decelerate from maximum frequency (E1-04) to minimum frequency (E1-09).

"

b3-05 Speed Search Delay Time



In cases where an output contactor is used between the Drive and the motor, extra waiting time is provided after power returns and before Speed Search is performed. This extra time allows for the contactor to operate. When Speed Search at start is used, b3-05 will serve as the lower limit of the Minimum Baseblock Time (L2-03).

The analog feedback to the Drive for the PI control is via the A2 terminal. The Drive must be programmed

(H3-09= “B: PI Feedback”) to use terminal A2 as feedback for the PI functionality of the Drive.

The PI setpoint can be configured to come from one of many different inputs or parameters. The table below describes the options for originating the PI setpoint.

The Drive can be used as a stand-alone PI controller. If PI functionality is selected by parameter b5-01, the Drive will adjust its output to cause the feedback from a transmitter to match the PI setpoint (b5-19). The setting of b5-01 will determine whether

PI functionality is disabled (b5-01= “0: Disabled”), enabled (b5-01= “1: Enabled”), or enable with the output of the

PI function used to trim a Speed Command (b5-01= “3: Fref+PI”).

"

b5-02 Proportional Gain Setting

Setting Range: 0.00 to 25.00

Factory Default: 2.00

The proportional gain will apply a straight multiplier to the calculated difference (error) between the PI Setpoint and the measured transmitter feedback at terminal A2. A large value will tend to reduce the error but may cause instability

(oscillations) if too high. A small value may allow to much offset between the setpoint and feedback (See Figure 5.14 on following page).

Programming 5 - 29

The Integral factor of PI functionality is a time-based gain that can be used to eliminate the error (difference between the setpoint and feedback at steady state). The smaller the Integral Time set into b5-03, the more aggressive the Integral factor will be. To turn off the Integral Time, set b5-03= 0.00.

b5-07 PI Offset Adjustment

Setting Range: -100.0% to +100.0%


The PI Offset Adjustment parameter has two different uses. Parameter b5-07 serves different functions depending on whether it is used on a standard PI loop or a Differential PI loop.

Parameter b5-07 causes an offset to be applied to the output of the PI function in a non-differential PI loop. Every time the PI output is updated, the offset (b5-07) is summed with the PI output. This can be used to artificially kick-start a slow starting PI loop.

If the Drive is configured for Differential PI Regulation (H3-09= “16: PI Differential”), then this parameter is the target setpoint for the differential to be maintained between the signal measured on analog input A1 and the signal measured on analog input A2.

Normally, the output of the PI function causes an increase in motor speed whenever the measured feedback is below the setpoint. This is referred to as direct acting response. However, if b5-09= “1: Reverse Output”, the output of the PI function causes the motor to slow down when the feedback is below the setpoint. This is referred to as reverse acting response.

"

b5-10 PI Output Gain Setting



Applies a multiplier to the output of the PI function. Using the gain can be helpful when the PI function is used to trim the

The Sleep Function can be programmed to prevent running the Drive when the PI loop output or the speed command is so low that no usable work is being done and/or equipment damage may result. The Sleep Function can be Enabled by entering a value in parameter b5-15. If the Drive’s output drops below the level set by the Sleep Function Start Level (b5-15) and remains there at least as long as the delay time determined by the Sleep Delay Time (b5-16), then the Drive’s internal Run command drops out and the Drive output ceases. Though the Drive’s output has ceased, all other Drive functions continue. Once the Drive’s theoretical output returns to a level above the Sleep Function Start Level (b5-15) and remains above that level for at least the

Sleep Delay Time (b5-16), the internal Run command returns and the Drive output begins again. The b5-16 Delay Time prevents oscillation about the sleep level. Note: The sleep function can be used even if the P1 function is disabled

The Snooze Function is a variation on the Sleep Function. The Snooze function must be selected by setting parameter b5-21= “2: Snooze”. Once the Snooze Function is selected, the Drive monitors the output frequency. If the output frequency drops below the PI Snooze Level (b5-22), and stays below that level for at least the PI Snooze Delay Time (b5-23), the Drive output shuts off. This is different from the Sleep Function because it is the feedback that must drop below the PI Snooze

Deactivation Level (b5-24) before normal Drive output will begin again. See Figure 5.19 on the following page.

"

b5-25 PI Setpoint Boost Setting


Factory Default: 0%

Just before the Snooze Function is activated, the PI Setpoint can be temporarily increased to create an overshoot of the intended PI Setpoint. The temporary boost is determined by the PI Setpoint Boost Setting (b5-25). Once the temporary boost level is reached (or the PI Maximum Boost Time (b5-26) is exceeded), the Drive output shuts off (snoozes) and the intended PI

Setpoint returns. From this point on, the Snooze Function operates normally and the Drive output returns when the feedback level drops below b5-24. See Figure 5.19 on the following page.

b8 Energy Savings

The energy savings function improves overall system operating efficiency by operating the motor at its highest efficiency. This

Description


Enabled

When the Energy Savings function is enabled (b8-01= “1: Enabled”), the Drive reduces the output voltage to the motor below

the voltage value specified by the programmed V/f pattern whenever the motor load is light. Since torque is reduced during this voltage reduction, the voltage has to return to normal levels when the load returns. The energy savings is realized through improved motor efficiency. The reduced output voltage causes increased rotor slipping even with a light load. A motor is most efficient when operating fully loaded (i.e. operating at rated slip).

"

b8-04 Energy Saving Coefficient Value


Factory Default: Model Dependent

Parameter b8-04 is used in maximizing motor efficiency. The factory setting will be Drive capacity dependent but can be adjusted in small amounts while viewing the kW monitor (U1-08) and running the Drive to minimize the output kW. A larger value typically results in less voltage to the motor and less energy consumption. Too large a value will cause the motor to stall.

C1-01 and C1-02 are the factory default active accel/decel “pair”. Another accel/decel pair (C1-03 and C1-04) exists that can be activated by a multi-function digital input (H1-0x= 7), or specified by a switch over frequency as programmed in parameter C1-11.

Note: In fan applications employing duct high pressure safety limit switches, it may be necessary to further adjust the deceleration time to avoid high pressure limit trips due to damper closure as the system is shut down (an alternate solution in this situation is to set parameter b1-03 to “Coast to Stop”).

"

A special deceleration parameter is available for use with emergency or fault operations. Parameter C1-09 will set a special deceleration that can be operated by closing a digital input configured as H1-0x= 15 or H1-0x= 17. A digital input configured as H1-0x= 15 will look for a switch closure before initiating the Fast Stop operation. A digital input configured as

H1-0x= 17 will look for the switch opening before initiating the Fast Stop operation.

Unlike a standard deceleration time, once the Fast Stop operation is initiated even momentarily, the Drive cannot be re-operated until the deceleration is complete, the Fast Stop input is cleared, and the Run command is cycled.

If one of the custom V/f patterns is selected, then parameters E1-04 through E1-13 will determine the V/F pattern.

IMPORTANT

When a factory Initialization is performed, the setting of E1-03 is unaffected but the settings of E1-04 through

E1-13 are returned to their factory default settings.

Increasing the voltage in the V/f pattern increases the available motor torque. However, when setting a custom V/f pattern, increase the voltage gradually while monitoring the motor current, to prevent:

• Drive faults as a result of motor over-excitation

• Motor overheating or excessive vibration

Table 5.8 is for 240V class units only. For 480V class units, multiply the voltage values by 2.

E2-01 Motor Rated Current

Setting Range: Model Dependent (see appendix B)


The Motor Rated Current parameter (E2-01) is necessary information for the Drive motor protection function. The motor overload protection parameter L1-01 is enabled by default. In addition, motor rated current is used by the torque compensation function to insure optimum torque production. Set E2-01 to the full load amps (FLA) value stamped on the motor’s nameplate. During Auto-tuning, it is required for the operator to enter the motor rated current in parameter T1-04 on the

Auto-Tuning menu. If the Auto-tuning operation completes successfully, the value entered into T1-04 will be also written into

E2-01.

For applications employing a Drive that is oversized for the motor, E2-01 may be set as low as 10% of the Drive output current rating. The ampere value in E2-01 however, must always be greater than the “No Load Current” value in parameter E2-03 or an OPE02 error will be displayed.

Programming 5 - 50

E2-03 No Load Current

Setting Range: Model Dependent (see appendix B)


Set E2-03 to the motor no-load current at rated voltage and rated frequency. Consult the motor manufacturer for the proper value if the no load current is not stated on the motor nameplate.

If a serial communication option board is attached to the Drive at the 2CN connector, the Drive will automatically monitor the card for any type of communication errors. F6-01 is applicable no matter whether a run command or speed command is coming via the option board, digital operator, or terminal input. The setting of F6-01 determines whether the communication error is seen as a fault or an alarm. If F6-01= “3: Alarm Only”, then the fault output is not energized upon a communication error. All other settings of F6-01 cause the fault output to energize. The setting of F6-01 does not apply to any of the embedded communication protocols used at the RS-485/422 terminals on the removable terminal board. (See parameters H5-0X)

If an external fault is received from the LonWorks

Parameter F6-02 will determine if the external fault is always recognized (F6-02= “0: Always Detected”) or only recognized when the Run command is active (F6-02= “1: Detected only during operation”).

Once the fault is recognized, parameter F6-03 will determine the operation of the Drive. If parameter F6-03 is set to anything other then “3”, the Drive will fault and a stopping sequence is begun. If F6-03= “3: Alarm Only”, then the external fault is treated like an alarm. Operation will continue and an EF0 fault will flash on the digital operator.

Function: Multi-step Ref 2

Setting: 4

The Drive can be programmed to step through four preset speeds and a jog. It is also possible to mix in the analog inputs as speed references that can be chosen in place of the first and second preset frequency references. The selection of which preset speed will be the active speed command is determined by the status of the digital inputs set for Multi-step Ref 1 (H1-0x= 3) and

Multi-step Ref 2 (H1-0x= 4). Changing the active speed command via the Multi-step References can be done while the Drive is running.

Programming 5 - 53

The following table details which reference is active based on the status of the Multi-step Ref 1 and Multi-step Ref 2 inputs:

Jog Frequency (d1-17)

The determination of whether the Preset Speed 1 will be the Frequency Reference 1 (d1-01 or the analog input A1) is determined by the status of b1-01. If b1-01= “1: Terminals”, the value of the input to A1 will determine the commanded speed when Preset Speed 1 is selected. If b1-01

≠

1, the setting of d1-01 will determine the commanded speed when Preset Speed 1 is selected.

The determination of Preset Speed 2 is made much the same way as Preset Speed 1 except that the setting of parameter H3-09 decides whether the analog input A2 or d1-02 is Preset Speed 2. If H3-09= “2: Aux Reference”, the value of the input to A2 will determine the commanded speed when Preset Speed 2 is selected. If H3-09

≠

2, the setting of d1-02 will determine the commanded speed when Preset Speed 2 is selected.

"

Function: Fault Reset

Setting: 14

Whenever the Drive detects a fault condition, the fault output contact will close and the Drive’s output will shut OFF causing the motor to coast (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). Once the Run command is removed, the fault can be reset by either the RESET key on the digital operator or by closing a digital input configured as a Fault Reset (H1-0x= 14).

"

Function: PI Disable

Setting: 19

When the PI Function has been enabled by b5-01 (PI Mode Selection), it can be indefinitely disabled by closing a digital input configured as a PI Disable input (H1-0x= 19). When disabled, the Drive operates as a standard Drive that does not have PI enabled.

"

Function: Com/Inv Sel 2

Setting: 6C

The Com/Inv Selection function allows the user to switch the origin of the Run and speed command between the Drive’s terminals and the RS-485/422 port (and the embedded communication protocols) on the removable terminal board. When a digital input is programmed for the Com/Inv Selection function (H1-0x= 6B) that input will function as follows:

H3 Analog Inputs

H3-02 Terminal A1 Gain Setting



H3-02 is one of the special parameter settings required by the Bypass logic circuit, depending on the options provided. See

Table 5.2.

The addition of another input signal on terminal A1 to the Drive and Bypass unit, after shipment to the job site, would be the only reason for changing this parameter.

For example, in variable air volume AHUs with a “volume matching” control strategy, P1 differential control is employed with feedback signals connected to both terminals A1 and A2.

"

H3-03 Terminal A1 Bias Setting



In order to have the Drive properly interpret an analog input, it may be necessary to apply a gain and/or a bias to the signal.

The analog inputs have a resolution of 10 bits (1024 steps). Using the factory default settings for the analog input’s gain and bias, the 0-10Vdc or 4-20mA signal at the analog input will yield a 0-100% speed command span.

Gain = 100%

Bias = 0%

0V

4mA

10V

20mA

Fig 5.24 Output Frequency as Commanded Via Analog Input

If a different span of analog input signal is desirable, it will be necessary to adjust the gain, the bias, or both to allow the analog input level to generate the desired frequency command. Adjustment of the gain setting will change the speed command that is equivalent to the maximum analog input (10Vdc or 20mA). If, for instance, the gain is increased to 200%, then 10Vdc or

20mA will be equivalent to a 200% speed command and 5 VAC or 12mA will be equivalent to a 100% Speed Command.

Since the Drive output is limited by the maximum frequency parameter (E1-04), 0-5Vdc or 4-12mA will now be equivalent to

0-100% speed command span.

Adjustment of the bias setting will likewise adjust the speed command that is equivalent to the minimum analog input level

(0Vdc or 4mA). If, for instance, the bias is set to –25%, then 0Vdc or 4mA will be equivalent to a –25% speed command.

Since the minimum speed command is 0% an analog input of 2.5 to10Vdc or 8 to 20mA will now be equivalent to 0-100% speed command span.

As a further example, for an inverse-acting speed command, set the bias= 100% and the gain= 0%. The minimum analog input level (0Vdc or 4mA) will produce a 100% speed command and the maximum analog input level (10Vdc or 20mA) will produce a 0% speed command.

The H3-08 parameter (Terminal A2 Signal Level) allows the programmer to specify the signal that will be applied to the A2 analog input. The A2 analog input can accept either a 0–10 Vdc or 4-20 mA signal as a reference. The Drive also has a DIP switch (S1) on the removable terminal board that must be set for the proper reference signal into the A2 analog input. The

S1-2 dipswitch setting determines the internal resistance of the A2 input while parameter H3-08 determines how the Drive interprets the measured signal.

Description

The A2 analog input can be programmed to perform many different functions. The setting of parameter H3-09 determines which of the following functions the A2 analog input will perform.

Function: Aux Reference

Setting: 2

In order for the A2 analog input to be used as the master Speed Command, parameter H3-09 must be set for Aux Reference

(H3-09= “2: Aux Reference”). Once A2 is configured as an auxiliary reference, it can be selected as the master Speed

Command by setting H3-13= “1: Main Fref TA2”. If H3-09= 2, terminal A2 analog input will become the speed command when a digital input programmed for Multi-Step Ref 1 (H1-0x= 3) is selected by a contact closure.

Function: PI Feedback

Setting: B

Configuring the A2 analog input as PI Feedback (H3-09= “B: PI Feedback”) is a requirement of setting the Drive up for PI operation. The A2 analog input is the only source for feedback for PI operation though the setpoint can come from a number of different sources (refer to the section covering the PI parameters for more information regarding specifying the setpoint source. PI parameters are listed in section b5).

Parameters H3-10 (Terminal A2 Gain) and H3-11 (Terminal A2 Bias) can be used to configure the A2 analog input to match the signal from the Feedback Transmitter.

The U1-24 monitor (PI Feedback) can be used to check the PI Feedback level with the digital operator.

Function: PI Differential

Setting: 16

Normal PI operation will adjust the Drive output in order to match the measured feedback value to a desired setpoint. When PI is operated in the differential mode, however, the Drive output is adjusted in order to maintain a desired differential between two feedback signals.

When the A2 analog input is configured as a PI Differential (H3-09= “16: PI Differential”), the A1 analog input becomes the other PI Differential input. The desired differential is set by parameter b5-07 (PI Differential Setpoint) and can be set so that

A2 is held less than A1 (b5-07 <0) or A2 is held greater than A1 (b5-07>0).

When PI Differential operation is chosen, the A1 feedback level can be monitored by U1-24 (PI Feedback) and the A2 feedback level can be monitored by U1-53 (PI Feedback2).

H3-11 Terminal A2 Bias Setting



Parameters H3-10 and H3-11 perform the same function for the A2 analog input that parameters H3-02 and H3-03 perform for the A1 analog input. Please refer to the parameter description for H3-02 and H3-03 for information about H3-10 and

H3-11.

These parameters could be used for final calibration of a factory or field installed pressure to electric transducer input connected to terminal A2 and AC. This field calibration may be needed if there is a job site variation from the typical 3 to 15

PSIG pneumatic signal input range.

"

H3-12 Analog Input Filter Time Constant



An analog input filter can be used to prevent erratic Drive control when a “noisy” analog reference is used. Parameter H3-12 sets the time constant for a first order filter that will be applied to both the A1 and A2 analog inputs. The Drive operation becomes more stable the longer the time programmed, but it becomes less responsive to rapidly changing analog signals.

For the A2 analog input to be an effective selection for the H3-13 parameter, parameter H3-09 must be configured as Aux Reference (H3-09= “2: Aux Reference”).

L2-02 Momentary Power Loss Ride-Thru Time



The Drive allows different responses to momentary power losses. The setting of L2-01 determines whether the Drive attempts to restart after a short loss of incoming AC power and for what length of time this capability remains active.

If L2-01= “0: Disabled”, the Drive detects a UV1 fault 15ms after power loss and automatic restarting is disabled. The Drive cannot restart until the external run command is removed and the UV1 fault is reset.

If L2-01= “1: PwrL Ride Thru t”, the Drive restarts without the UV1 fault if power is returned within the time specified in

L2-02, the Momentary Power Loss Ride-thru Time. During the power loss but before the fault trip, the digital operator will display a UV alarm. If L2-02 is set for a time longer than the control power supply can be sustained, a UV1 fault will not occur and the Drive restarts upon the return of AC power. The time that the control power supply can be maintained varies with

Drive size. The larger the Drive, the greater the potential ride-thru time.

If L2-01= “2: CPU Power Active”, the Drive ignores L2-02 and attempts a restart as long as the control power supply is still able to maintain a minimal voltage level. In effect, setting L2-01= “2: CPU Power Active” (factory default) is programming the Drive for maximum Power Loss Ride-thru. An equivalent setting is L2-01= “1: PwrL Ride Thru t”, with L2-02 set to a time longer than the control power supply can be maintained after power is lost.

Note:

The run command must be held during power loss for any power loss ride-thru capability to be possible. It is for this reason that 3-wire control is not recommended for use with the Momentary Power Loss function.

If L3-01= “1: General Purpose”, then the standard stall prevention function is enabled. When the output current exceeds the level set by the L3-02 parameter, the Drive will discontinue accelerating and maintain speed. If, during acceleration, the output current comes within 15% of the level set by parameter L3-02, the acceleration time is lengthened. Once the output current level has dropped below the L3-02 level, acceleration will begin again with the acceleration rate reaching the programmed rate once again 15% below the L3-02 level.

L3-06 Stall Prevention Level During Running



The Stall Prevention During Running function will attempt to avoid a Drive OC fault occurrence while the Drive is operating at a constant speed. If L3-05= “0: Disabled”, the Drive may fault if the load increases sufficiently to cause the output current to reach the OC fault level (180% of Drive rated output current).

If L3-05= “1: General Purpose”, the Drive is outputting a constant speed, and the Drive’s output current level exceeds the level set by parameter L3-06 for more than 100 ms the Drive will begin to decelerate at the rate specified by parameter C1-02. The

Drive will continue to decelerate until the output current level drops below the L3-06 level (less a 2% hysteresis). Once the output current drops below the L3-06 – 2% level the Drive will begin to accelerate at the currently active acceleration rate

(either C1-01 or C1-03).

If L3-05= “2: Decel Time 2”, the Drive will function as described above except C1-04 will be used instead of C1-02 as the deceleration rate used when the output current exceeds L3-06 for more than 100 ms.

L5-03 Maximum Restart Time After Fault



All major faults will cause the Drive to stop. For some faults it is possible to configure the Drive to attempt a restart automatically. After the fault occurs, the Drive baseblocks for L2-03 seconds. After the baseblock is removed the Drive checks if a fault condition still exists. If no fault condition exists the Drive will attempt to restart the motor. If the restart is successful, the Drive performs a Speed Search (Regardless of the status of b3-01 “Speed Search Selection”) from the set speed command and the Auto Restart Attempts count is increased by one. Even if the restart fails the restart count is increased by one as long as the Drive attempted to rotate the motor. The restart count will not be incremented if the restart is not attempted due to a continuing fault condition (i.e. an OV fault). The Drive waits L5-03 seconds before attempting another restart.

The setting of parameter L5-02 determines whether the fault output (MA-MB) will be closed during an auto restart attempt.

The setting of L5-02 can be important when interfacing the Drive with other equipment.

The following faults will allow the Auto Restart function to initiate:

• OC (Overcurrent)

• LF (Output Open Phase)

• PF (Input Phase Loss)

• PUF (DC Bus Fuse)

• OL1 (Motor Overload)

• OL3 (Overtorque)

• OL2 (Drive Overload)

• OV (DC Bus Overvoltage)

• GF (Ground Fault)

• UV1 (DC Bus Undervoltage)

• OH1 (Overheat)

In order for auto restart after a UV1 fault, Momentary Power Loss Ride-thru must be enabled (L2-01= “1: PwrL Ride Thru t”, or “2: CPU Power Active”). Setting H2-01 or H2-02 equal to “1E” configures a digital output as “Restart Enabled” to signal if an impending auto restart is possible.

L6-03 Torque Detection Time 1



The Drive can be programmed to indicate when either an overtorque or an undertorque conditions exist. A digital output must be programmed for “Torque Detection”, (H2-01/H2-02= “B: Trq Det 1 N.O.” or “17: Trq Det 1 N.C.). A warning of an overtorque condition can indicate a jam and an undertorque condition can indicate a broken belt, no water in a pump, or other loss of load.

To configure Torque Detection requires the following decisions:

1.

Do you wish to check for an overtorque condition or an undertorque condition?

2.

Do you wish to check for the torque condition whenever the Drive is running or only at speed agree? Nuisance detection during acceleration, when variable torques are normally required, can be avoided.

3.

Do you want the Drive to fault if the torque condition is detected or only alarm and continue operation?

L8-11 Heatsink Cooling Fan Operation Delay Time



Parameters L8-10 and L8-11 allow the Drive programmer to customize the heatsink cooling fan operation. Parameter L8-10 determines whether the cooling fans are always ON whenever the Drive is powered (L8-10= “1: Fan Always On”) or if the cooling fans are only ON when the Drive is in a Run condition (L8-10= “0: Fan On-Run Mode”).

Parameter L8-11 is a delayed OFF for the cooling fan if L8-10= “0: Fan On-Run Mode”. When the cooling fans are set to turn

OFF when the Run command is removed, parameter L8-11 will cause the fans to continue cooling the Drive for the amount of time programmed into L8-11 after the Run command is actually removed. The Drive can be programmed to allow the cooling fan to run for up to 5 minutes (factory default) after the run command is removed.

Both parameters are intended to extend fan life while still providing sufficient cooling for proper Drive operation.

L8-19 Overheat Frequency Reference Reduction Level

Setting Range: 0.0 to 100.0% of maximum frequency

Factory Default: 20.0% of maximum frequency

When the heatsink temperature reaches the OH Pre-alarm level (L8-02) and the Overheat Pre-Alarm Operation Selection parameter is set for Alarm and Reduce (L8-03= “4: OH Alarm & Reduce”), the L8-19 parameter sets the amount of speed decrease that will be applied to the Speed Command in order to lower the heatsink temperature. The decrease in speed will lower the current being switched and conducted by the heat producing output transistors of the Drive.

Parameter L8-19 is set in percentage of maximum frequency (E1-04).

User Monitor (set by o1-01)

When the Drive is powered up, three monitors are displayed on the digital operator. The first and largest monitor is the

“Power-On” monitor. The factory default “Power-On monitor” is Speed Command (U1-01). Below the Speed Command monitor are the next two sequential monitors, Output Frequency (U1-02) and Output Current (U1-03). Pressing the

INCREASE key once scrolls the monitors to show the User Monitor as selected by o1-01. The factory default for o1-01 is the

Output Voltage monitor (U1-06).

The active monitor displayed when the Drive is powered on can be changed to either be U1-01 (Speed Command), U1-02

(Output Frequency), U1-03 (Output Current), or the User Monitor. Whichever monitor is selected as the Power-On top monitor, the two monitors displayed below it are the next two sequential monitors. See example below.

If Digit 5 = 1 number format is XXX.X

If Digit 5 = 2 number format is XX.XX

If Digit 5 = 3 number format is X.XXX

For example:

If o1-03= 10425, then at full speed the digital operator will display “42.5”. Configuring parameter o1-03 for displaying in terms of an engineering unit is only appropriate if the actual display units have a linear relationship with the actual output speed.

Description

The Drive gives the option of configuring any and all of the programming parameters and then saving the parameters as “User

Initialization Values”. After configuring the Drive, set parameter o2-03= “1: Set Defaults”, to save the parameters to a User

Initialization memory location. Once this has been done, the “Initialize Parameters” parameter (A1-03) will offer the choice of

“1110:User Initialize”. Choosing A1-03= “1110: User Initialized”, will reset all modified parameters back to what they were the last time they were saved using o2-03.

The choice of setting A1-03= “1110: User Initialized”, is unavailable until first setting the User Initialization parameters using o2-03. Once a User Initialization is set (saved), it can be cleared by setting o2-03= “2: Clear All”. After clearing the User

Initialization parameters, the choice of “1110: User Initialize” is no longer a available in A1-03.

The factory default setting of the Frequency Reference Setting Method parameter (o2-05= “1: Enabled”) dictates that when setting a Speed Command via the digital operator (“Hand” mode), it is not necessary to press the DATA/ENTER key before the Drive will begin to accelerate or decelerate to the new set speed. This is referred to as MOP (Motor Operated

Potentiometer) type functionality. When o2-05= “1: Enabled”, the speed command is stored to memory 5 seconds after the

INCREASE or DECREASE keys are released.

When o2-05= “0: Disabled”, the digital operator INCREASE and DECREASE keys will change the speed command but the

Drive will not accelerate or decelerate to the new speed command until the DATA/ENTER key is pressed. In order to change the Speed Command in the HAND mode, U1-01 must be the top monitor and then the ENTER key must be pressed in order to access the Speed Command function. This in not to be confused with pressing the ENTER key in order to achieve a change in speed using the INCREASE and DECREASE keys, which is the subject of parameter o2-05.

Leaving o2-06 enabled will cause the Drive to fault, when the digital operator is removed, even if it’s not outputting to the motor. The reset key on the digital operator will need to be pressed after reconnecting the digital operator to reset the fault and continue normal operation.

If o2-06 = “0: Disabled” then the Drive will not fault if the digital operator is disconnected, but the Drive will discontinue motor operation. If full Drive operation is required while the digital operator is removed set o2-06 = “0: Disabled” and o2-15 = “0: Disabled” (Hand Key Function). If both o2-06 and o2-15 are disabled then the digital operator can be disconnected without disturbing Drive operation.

Auto tuning is recommended to achieve optimum performance. In addition, the Drive requires Line-To-Line Resistance auto-tuning before it can properly perform the Estimated Speed Search method. This method of speed search allows for bi-directional speed search. The T1 parameters are found under the Auto-Tuning menu.

"

Auto-Tuning Using DriveWizard

DriveWizard is a PC software program designed to provide the tools necessary to handle Drive installation as well as parameter record keeping and maintenance. As such it provides an Auto-Tuning method for Drives in Bypass units. The

Auto-Tuning function “tunes” the Drive setup to the characteristics of the specific motor to which it is applied. Auto-Tuning is essential if bi-directional Speed Search is required and enabled for the application.

DriveWizard can be obtained either through CD or www.Drives.com. Follow the installation procedures provided with the software.

With the DriveWizard software loaded onto a PC, connect a standard CAT 5 Ethernet cable from the PC’s RS-232 port (with a

DB-9 to CAT 5 adaptor) to the digital operator/keypad port on the Drive. Before disconnecting the digital operator/keypad from the Drive, set parameter o2-06 (“Oper Detection”) to “0:disabled”. This will allow the Drive to continue running with the digital operator/keypad removed.

Start DriveWizard and setup the PC communications by setting the appropriate communications port and Baud rate. Typical settings are Com Port 1 and 9600 Baud.

Once the communications port is set, connect to the Drive by clicking on the pull-down menu “Inverter” and selecting

“Connect.” [This can also be done by typing Ctrl+C on your keyboard, or by clicking on the yellow icon resembling two puzzle pieces.] This will upload all of the current parameters in the Drive to the computer as a working parameter file.

At this point the parameters can be saved as a backup file if desired. [DriveWizard is a third method of saving the complete parameter list and user settings. In addition to the “User Parameters” (o2-03) and “Keypad Copy” (o3-01) functions discussed in this chapter, DriveWizard can be employed to maintain a downloadable list of the Drive parameter set up on a PC, for backup or transfer to other drives.]

Auto-Tuning is performed by selecting the Auto-Tuning function from the “Inverter” pull-down menu. DriveWizard will ask you to verify that the motor is in a safe operating condition, and then ask you to enter two parameters. DriveWizard will ask you to fill in parameters T1-02 “Mtr Rated Power” and T1-04 “Rated Current”. After this data has been entered, click on the

“Load” button to enter these values into the Drive memory. The “Start” button will become available, click on “Start” to begin the auto-tuning process. While Auto-Tuning is running the Drive output current and frequency will be displayed, the flashing green light indicates DriveWizard is communicating with the Drive. When complete, DriveWizard will have auto-tuned the

Drive, adjusted several motor related parameters and the Drive will be ready for optimum performance for bi-directional Speed

Search and other functions.
