This Manual provides information for the correct use of the CTW-04. As the CTW-04 is very flexible, it permits also other operation modes than those described in this Manual. As the CTW-04 can be applied in several ways, it is impossible to describe here all application possibilities. Thus
WEG does not accept any responsibility, when the CTW-04 is not used according to this Manual.
This Manual may not be reproduced partially or totally in any form without the written consent of WEG.
It is important to note the Version of the Software installed in the CTW-04, since it defines the functions and parameter setting. This Manual refers to the Version of the Software indicated on the inside cover. For instance,
Version 1.0X applies to versions 1.00 to 1.09, where “X” is a variable that will change due to some minor software revisions covered by this version of the manual.
The version of the Software can be read at Parameter P023.
The CTW-04 series is intended for driving of DC-motors with independent excitation by changing and controlling the speed in 1 or 4 quadrants (see
Note (1)) according to the torque x speed curve. The main characteristics of this drive are:
It operates at any sequence of the supply phase (RST - RTS);
It operates at 50/60 Hz three-phase lines;
HMI (Human-Machine-Interface);
It indicates the four last faults;
Isolated digital inputs (bi-directional current);
Isolated digital outputs;
Differential analog inputs from - (0 to 10)V or from (4 to 20)mA - 10 and
12 bits (see Note (2));
21
CHAPTER 2 - GENERAL INFORMATION
Analog outputs – 8 and 12 bits (see Note (4));
Digital relay outputs;
Field Current Control – Ic;
Speed feedback by: back-EMF, DC-tachogenerator or incremental encoder (see Note (3));
Feedback inputs by DC-tachogenerator for tachogenerator voltages from 9 to 350Vdc;
24Vdc isolated sources available for the user (DI’s and DO’s);
Power supply from 0 to 10V available for the user (Al’s);
Field weakening – +EC (see Note (4));
Field supply up to 440V;
Fieldbus communication networks (Profibus-DP and DeviceNet);
RS-232 serial communication.
NOTES!
(1) - The 1 quadrant or 4 quadrants CTW-04 converter is determined by the intelligent product code:
1 quadrant – Unidirectional. Ex: CTWU4XXXXTXXXXXZ
4 quadrants –Antiparallel. Ex: CTWA4XXXXTXXXXXZ
(as described in this Chapter: “How to specify the CTW-04 model”)
(2) - The CTW-04 converter provides:
4 AI’s [10 bits];
1 AI [12 bits];
3 AO’s [8 bits];
2 AO’s [12 bits].
12 bits Inputs and Outputs are available only in the models where the
CCW4.00 - Full (F – full version) control board is specified.
Ex:CTWX4XXXXTXXXFXZ
(3) - When speed feedback with incremental encoder is required, CTW-04 converter must be fitted with CCW4.00 – Full (F – full version) control board.Ex:CTWX4XXXXTXXXFXZ
(4) - Operation in the Filed Weakening area (+EC) can be carried out only when the speed feedback is not realized by back-EMF.
For more details about the product models and other technical information, see Chapter 9.

3.2.2 Grounding
ATTENTION!
Do not use the neutral wire for grounding purpose.
The converter supply line should have neutral connector grounded solidly.
Converter grounding to a protection earth is mandatory (PE). The herth or ground connection must comply with the local regulations. For grounding, use cable cross-section
4mm². Make ground connection to a specific grounding bar or to the general grounding point (resistance of 10 ohms). Do no share the ground wiring with other equipment that operates with high current (for instance, high voltage motors, welding machines, etc.).
Make the grounding connection of the CTW-04 control and power as shown below:
Heat Sinker
X1
PE
Figure 3.9 – Control and Power Grounding Connection
NOTE!
The AC input voltage must be compatible with the converter rated voltage (see models on item 2.4);
When electromagnetic interference (EMI), generated by the converter, causes problems with other equipment, use shielded wires, or install the motor wires in metallic conduits. Connect on end of the shielding to the converter grounding point and the other end to the motor frame;
Capacitors for power factor correction are not required at the input and they must not be connected at the converter output.
Always ground the motor frame. Ground the motor in the panel, where the converter is installed, or ground it to the converter. The converter output wiring must be laid separately from the input wiring, and also from the control and signal cables.

Functions of the Digital Inputs:
Funtion
BG (General Disable):
0V (Active)
shows F01 on the Display. If the disable through stop logic is active, it deactivates the output XC1:28 (Release), disables the ramp and the regulators, and after ½ network cycle it disables the firing. If any key is activated, the indication of
F01 on the display is replaced by the previous indication (the one that was being displayed before the occurrence of the
General Disable).
24V (Inactive) removing the general disable command will cause a delay of about 0.1s for releasing the speed ramp, regulators, firing and the activation of the digital output XC1:28. The indication on the display is replaced by the previous indication (the one that was being presented before the occurrence of the General Disable).
BR or
(Ramp disable or decelerates P.E.):
BR (Ramp disable)
Quick ramp disable (P009 = 1) or slow ramp disable (P009 = 0). Active with 24V.
(Decelerates P.E.) Active with 0V (P024 = 5).
The quick/slow disable resets the ramp input/output, respectively.
L
R or (Local/Remote Speed Reference or Accelerates P.E.):
L
R (Local/Remote Speed Reference ) selects the origin of the analog speed reference (0V = remote, 24V = local).
(Accelerates P.E.) Active with 24V
EE (External Error):
This input can monitor, for instance, the heatsink thermostat, the thermostat of the DC motor, the ultra-rapid fuse blow-out, etc.
For this purpose, connect the sensor contacts in series (0V = defective, 24V = no defective).
(direction of rotation):
It reverses the polarity of the speed reference
(0V = clockwise, ± 24V = counter-clockwise).
DI (Programmable Digital Input):

The CTW-04 can be controlled, set and monitored through the RS-232 serial interface. The communication protocol is based on the enquiry/ response type, according to ISO 1745, ISO 646, with ASCII character exchange between the converters and a master (network controller may be a PLC, PC, etc.). The max. transfer rate is 9600 bps. The RS-232 serial interface is point-to-point and is not galvanic isolated against 0V
(which is grounded in the converter electronics) and allows installation at distances up to 10m.
The connection of the RS-232 serial communication is realized through the
RJ12 - XC3 connector, available on the CCW4 control board, via serial cable.
See Chapter 8 for more details.
3.2.4.4 Description of the
Incremental Encoder
Connector - XC4
NOTE!
The XC4 signal and control connector is only available on the CTW-04 converter models, where the CCW4.00 - Full (F – Full Version) control board is specified – according to intelligent product code.
Ex:CTWX4XXXXTXXXFXZ
In the applications where higher speed accuracy is required, the speed feedback of the motor shaft must be realized by means of Incremental
Encoder.

The required encoder should have the following characteristics:
Supply voltage: +5V or +8V to +15V, with consumption lower than 200mA;
2 quadrature channels (90º) + zero pulse with supplementary outputs
(differential): Signals A, A’, B, B’, Z and Z’;
“Linedriver” or “Push-Pull” output circuit type (+5 to +15V);
Electronic circuit isolated against encoder frame;
Recommended number of pulses per turn: 1024 ppr.

Figure 3.42 - Required Encoder signal sequence
For mounting the Encoder on the motor, proceed as follows:
Couple the encoder direct on the motor shaft (by using a flexible coupling, without torsion flexibility);
Both encoder shaft and metallic encoder frame must be electrically isolated from the motor (min. spacing: 3 mm);
Use couplings of reasonable quality, which prevents mechanical oscillation or backlash;
Electrical connection must be realized with shielded cables. Maintain a min. distance (>25cm) from the other wirings (power, control, etc.).
If possible, install them into metallic conduits.

NOTE!
During start-up it’s necessary to program the parameters below to operate the drive through incremental encoder speed feedback:
P025
Type of Speed Feedback = 04.
P052, P053
Max. Frequency of the Pulse Tachogenerator (FTM): make setting according to the number of pulse per turn of encoder (ppr) andaccording to the max. motor speed (vmm).
Example: Encoder with 1024 ppr and vmm = 2100 rpm, then:
FTM
2100

143 .
360
pulses
Thus: P053 = 143 and P052 = 360.
Example of pin location of the HS35B encoder cable - Dynapar:
When other encoder models are used, check correct pin connections to meet the required sequence.

START-UP
This chapter provides the following information:
How to check and prepare the converter for power-up;
How to power-up and check for proper operation;
How to operate the converter when installed according to typical connections.
The converter must be installed according to Chapter 3 – Installation. Also if the drive design is different from the typical suggested operation, proceed as follows:
DANGER!
Always disconnect the AC input power, before making any connection.
ATTENTION!
Check if the phases R, S, T are connected in the same order in the control and in the power bar.
1. Check all Connections.
Check if the power, grounding and control connections are correct and well tightened.
2. Clean the inside of the inverter.
Remove all chipping material from the inside of the converter or drive.
3. Check if the correct converter has been selected.
4. Check the motor.
Check all motor connections and verify if its voltage, current and frequency match the converter specifications.
5. Uncouple the load from the motor.
If the motor cannot be uncoupled, make sure that the direction of rotation (FWD/REV) cannot cause personal or machine damages.
6. Check Converter Nameplate Data.
Check if the electronics, armature and field supply matches the data of the converter nameplate.
7. Close the converter cover or cabinet doors.
8. Check fan operation (motor and converter).

POWER-UP/
START-UP
1. POWER-UP
Procedures to be adopted for CTW-04 converter start up:
Power-up only the electronics of the product (X1:1,2,3);
Converter must be disabled (General Disable
XC1:27 = 0V), F01 indication.
Set P002 = 1 (external field control), to disable the current supply of the DC-motor field.
DANGER!
Do not power-up the armature.
2. PARAMETER CHANGE
To change the parameters of the Operation mode, set P004 = 0.
If P004 = 1, then set P013 = 1. This procedure changes P004 to 0 automatically and makes available the parameter change of the Operation Mode.
The Regulation Parameters may be changed at any time indifferent the setting at P004.
After parameter has been changed, set P004 = 1.
To save the change, set P000 = 0005.
NOTE!
Detailed description of the Parameter change are shown at chapter 8.
3. SET THE PARAMETERS ACCORDING TO THE APPLICATION
Set the Parameters by using the “Quick Parameter Reference” and the Chapter 6: “Detailed Parameter
Description”, according to the converter application.
4. SET THE FIELD PARAMETERS
Change the filed parameters according to the DC-motor nameplate data.
P060 = Rated current
P061 = Minimum Field current
P100 = Economy field current

DI Function Description
This function enables the speed regulator to operate with 2 distinct sets of PI gains
(according to the application example mentioned in Parameter P007). When DI is open (0V), the gains of P039 and P040 are used. When DI is closed (+24V), the PI gains of the regulator are those defined at P048 and
P049.
Permits commutation between Serial defined at P019 to P022 to command via DI’s. (0V commands via DI; 24V - command via serial).
(reserved to special Software functions).
It permits the commutation between Fieldbus defined at P019 to P022, to command via
DI's. (0V - command via DI; 24V - command via Fieldbus).

DIAGNOSTICS AND TROUBLESHOOTING
This chapter assists the user to identify and correct possible faults that may occur during the CTW-04 operation. Guidance on Periodical Inspection,
Preventive Maintenance and Cleaning Procedures are also provided.
7.1
ERRORS/FAULTS AND
POSSIBLE CAUSES
7.1.1
Errors and Possible
Causes
When an error or a fault is detected, the converter is disabled and the
Error/Fault Code is displayed on the readout in the EXX or FXX. To restart the converter after an error/fault has occurred, the converter must be reset.
The reset can be made as follows:
Disconnecting and reapplying AC power (Power-on reset);
Automatic reset after some time has elapsed (Auto-reset);
Via Digital Input: EE (XC1:33).
Self-diagnose of some signals is executed (during approx. 3s) after converter is powered up, as follows:
+5V power supply tolerance;
Actuation of the external counter;
Synchronism with line voltage.
Error/Fault Code E02 to E05 is displayed, if some problem is detected and the converter is disabled.
For details about errors and possible causes, refer to Table below:

FIELDBUS NETWORK
COMMUNICATION
OPTIONS AND ACCESSORIES
This chapter describes the optional devices that are available for the CTW-04 converter. These optional devices are: Fieldbus network communication kit, RS-232 communication kit to PC and blank covers.
The CTW-04 can be connected to Fieldbus networks allowing its control and parameter setting. For this purpose you need to include an optional electronic board according to the desired Fieldbus standard: Profibus-DP or DeviceNet.
NOTE!
The chosen Fieldbus option can be specified in the suitable field of the
CTW-04 coding:
DN = DeviceNet
PD = Profibus DP
EX: CTWX4XXXXTXXXXODNZ = CTW-04converter withoptional DeviceNet.
In this case the CTW-04 will be supplied with all needed components already installed for the Fieldbus communication.
For later installation you must order and install the desired Fieldbus communication kit (Profibus-DP or DeviceNet).

CHAPTER 8 - OPTIONS AND ACCESSORIES
8.1.1.2 Introduction The converter that is fitted with the Profibus-DP kit operates in slave mode, allowing the reading/writing of the parameters through the master. The converter does not start the communication with other nodes, it only responds to the master. A twisted pair of shielded copper cable realizes the connection the Fieldbus (RS-485), allowing the data transfer at rates between 9.6kbits/s to 12Mbits/s.

8.1.1.3 Technical Interface
CHAPTER 8 - OPTIONS AND ACCESSORIES
Line Termination
The initial and the end points of the network must be terminated with the characteristic impedance in order to prevent reflections. The DB9 male connector of the cable has the suitable termination. When the converter is the first or the last of the network, you must set the termination switch to
“ON”. Otherwise set the switch to “OFF”. The terminating switch of the
PROFIBUS-DP board must be set always to 1 (OFF).
Transfer Rate (Baudrate)
The transfer rate of a Profibus-DP network is defined during the Master configuration and only one rate is permitted on the same network. The
Profibus-DP board has automatic baudrate detection and the user does not need to configure it on the board. The supported baudrates are: 9.6
kbits/s, 19.2 kbits/s, 45.45 kbits/s, 93.75 kbits/s, 187.5 kbits/s, 500 kbits/ s, 1.5 Mbits/s, 3 Mbits/s, 6 Mbits/s and 12 Mbits/s.
Node Address
The node address is established by means of two rotating switches on the electronic Profibus-DP board, permitting the addressing from 1 to 99 addresses. Looking onto the front view of the board with the converter in normal position, the switch at left sets the set of ten of the address, while the switch at right set the unit of the address:
Address = (set left rotary switch x 10) + (set right rotary switch x 1)
Configuration File (GSD File)
Each element of the Profibus-DP board is associated to a GSD file that has all information about the element. This file is used by the program of the network configuration. Use this file with the extension .gsd stored on the floppy disk contained in the Fieldbus kit.
Signaling
The electronic board has a bicolor “LED” at the right topside, indicating the status of the Fieldbus according to the table below:

CHAPTER 8 - OPTIONS AND ACCESSORIES
8.1.2.2 Introduction The DeviceNet communication is used for industrial automation mainly for the control of valves, sensors, input/output units and automation equipment. The DeviceNet communication link is based on a communication protocol “broadcast oriented”, the Controller Area Network
(CAN). The connection to the DeviceNet network is realized by means of a shielded cable comprising a twisted pair and two-wire cable connected to the external power supply. The baudrate can be set to 125k, 250k or
500kbits/s.
Figure 8.7 gives a general view of a DeviceNet network:

Line Termination:
To prevent deflection, the initial and the end points of the network must be terminated with the characteristic impedance in order to prevent reflexions.
Thus a 120 ohms/0.5W resistor must be connected between the pins 2 and 4 of the Fieldbus connector.
Baudrate / Node address:
There are three different baudrates for the DeviceNet: 125k, 250k or
500kbits/s. Select one of these baudrates by setting the DIP switches on the electronic board, before configuration is made. The node address is selected through the six DIP switches on the electronic board, permitting an addressing from 0 to 63 addresses.

CHAPTER 8 - OPTIONS AND ACCESSORIES
8.1.3 Use of the Fieldbus/ related Parameters of the CTW-04
8.1.3.1 Variables Read From
Converter
There are two main parameters: P085 and P086.
P085 - defines the used standard Fieldbus (Profibus-DP or DeviceNet) and the number of (I/O) variables exchanged with the Master (2, 4 or 6).
The Parameter P085 has the following functions:
0 = Inactive;
1 = Profibus-DP 2I/O,
2 = Profibus-DP 4I/O,
3 = Profibus-DP 6I/O,
4 = DeviceNet 2I/O,
5 = DeviceNet 4I/O,
6 = DeviceNet 6I/O.
P086 - defines the converter behavior when the physical connection with the Master is interrupted and/or Fieldbus board is inactive (E29/E30 indicated on the HMI display).
The parameter P086 has the following functions:
0 = disables the converter by using the Ramp Disable command, via deceleration ramp (if P005 = 1).
1 = disables the converter by using the General Enable, stop by inertia
2 = the inverter status is not changed.
1. The variables are read in the following sequence:
1- Logical Status of the converter;
2- Motor speed, for option P085 = 1 or 4 (2I/O) – it reads 1 and 2;
3- Status of the Digital Inputs (P098);
4- Parameter status, for option P085 = 2 or 5 (4I/O) – it reads 1, 2, 3 and 4;
5- Armature current (P089);
6- Motor Field Current (P062), for option P085 = 3 or 6 (6I/O) – it reads 1,
2, 3, 4, 5 and 6.
Logical Status (E.L.):
The Word that defines the E.L. is formed by 16 bits, being 8 bits of high order and 8 bits of lower order. It has the following structure:
High-Order Bits – they indicate the status of the associated function
EL.15 – Not used;
EL.14 – JOG command- : 0 = Inactive, 1 = Active;
EL.13 – JOG command+ : 0 = Inactive, 1 = Active;
EL.12 – Fault active: 0 = Yes, 1 = No;
EL.11 – Error active: 0 = Yes, 1 = No;
EL.10 – Direction of rotation: 0 = Counter-Clockwise, 1 = Clockwise;
EL.09 – General Disable: 0 = Active, 1 = Inactive;
EL.08 – Disable by Ramp: 0 = Inactive, 1 = Active.
Low-Order Bits – they indicate the fault code number (i.e. 02 to10).
See item 7 - Faults and Possible Causes.
2. Motor Speed:
This variable is shown by using a 4 bits resolution plus signal. I.e., when the parameter P088 (Motor Speed) shows 100% (motor operating without field weakening), the value read at pos. 2 will be equal to 16383(3FFFh) for clockwise rotation, or –16383(C001h) for Counter-Clockwise rotation.
110
CHAPTER 8 - OPTIONS AND ACCESSORIES
8.1.3.2 Variables written to the
Converter
3. Status of the Digital Inputs:
It indicates the content of the parameter P098, where level 1 indicates active input (with +24V) , and the level 0 indicates inactive input (with 0V).
The digital inputs are so distributed in this byte:
Bit.7 – XC1:37 status (DI programmable);
Bit.6 – XC1:41 status (JOG - );
Bit.5 – XC1:39 status (JOG +);
Bit.4 – XC1:33 status (External Error);
Bit.3 – XC1:31 status (Accelerates PE, Loc/Rem);
Bit.2 – XC1:35 status (Direction of rotation);
Bit.1 – XC1:29 status (Ramp Disable or Decelerates PE);
Bit.0 – XC1:27 status (General Disable).
4. Parameter Content status:
Through this position you can read any converter parameter that is selected at Position 4 - parameter number to be read, of “Variables written to the converter”. The read values have the same order as those described in the
Product Manual or displayed at the HMI.
The values are read without decimal dot, i. e., the HMI indication is multiplied by 10 at the parameters: P032, P033, P036, P039 to P042, P048 to P051,
P052 to P061, P063, P064, P066, P078 to P080.
The read values are multiplied by 100 at the parameters: P032, P033 when
P014=1.
Example: a) HMI displays 12.3, the read via Fieldbus will be 123.
5. Armature Current:
The armature current (P89) is displayed without decimal dot. A 0,06 sec.
filter is fitted.
6. Field Current:
This position indicates the content of Parameter P062, disregarding the decimal point.
The variables are written in the following order:
1 - Logical Command;
2 - Motor speed reference, for option P085 = 1 or 4 (2I/O) - writes in 1 and 2;
3 - Status of the Digital Outputs;
4 - Number of parameters to be read, for option P085 = 2 or 5
(4I/O) – writes in 1, 2, 3 and 4;
5 - Number of Parameter to be changed;
6 - Content of the parameter to be changed, selected at the previous position, for option P085 = 3 or 6 (6I/O) – writes in 1, 2, 3, 4, 5 and 6.
1. Logical Command (C.L.):
The Word that defines the C.L. is formed by 16 bits, being 8 bits of highorder and 8 bits of lower-order. It has the following structure:
High-Order Bits – they select the function that should be enabled when the bit is set to 1.
111
CHAPTER 8 - OPTIONS AND ACCESSORIES
CL.15 – Reset of the converter faults;
CL.14 – Not used;
CL.13 – Not used;
CL.12 – JOG - command ;
CL.11 – JOG + command;
CL.10 – Command of Direction of Rotation;
CL.09 – Command of General Disable;
CL.08 – Command of Ramp Disable.
Low-Order Bits – they determine the status desired for the selected function at the high-order bits.
CL.7 – Reset of the converter faults: always when transition 0
1 occurs, the converter reset will be enabled.
CL.6 – Not used;
CL.5 – Not used;
CL.4 – Command JOG - : 0 = Inactive, 1 = Active;
CL.3 – Command JOG + : 0 = Inactive, 1 = Active;
CL.2 – Direction of Rotation: 0 = counter-clockwise, 1 = clockwise;
CL.1 – General Disable: 0 = Active, 1 = Inactive;
CL.0 – Ramp Disable: 0 = Active, 1 = Inactive.
To enable the Fieldbus to control the Speed Reference and/or functions:
Logical Command (fault reset, JOG+, JOG-, Direction of Rotation, General
Disable, and Ramp Disable), you must select the desired option through following parameters: a) Speed reference = P019; b) Direction of rotation = P021; c) General Disable, and Ramp Disable = P020; d) JOG+/JOG-selection = P022; e) P065 = 3.
NOTE!
For controling the parameters selected at P019 to P022 via Fieldbus, the progammable DI (XC1:37) must be active (24V).
2. Motor Speed Reference:
This variable is displayed by using a 14 bits resolution. When Parameter
P087 (total Speed Reference) shows 100% (motor operating without field weakening), the Speed Reference will be 16.383 (3FFFh) and always positive. To reverse the direction of rotation, use bits CL.10 and CL.2 from
Logical Command.
3. Not used.
4. Parameter Number to be read:
Through this setting you can read any converter parameter. For this purpose you must enter the number of the desired parameter and its content will be displayed at pos. 4 of the Read Converter Variables”.
5. Parameter Number to be changed:
(Changing Parameter Content)
This Position works jointly with Position 6 below. If no Parameter changing is desired, insert at this Position code 999.
112
8.1.3.3 Error Indication
CHAPTER 8 - OPTIONS AND ACCESSORIES
During the changing process you must:
1) Program the desired content at Pos. 6 below;
2) Replace the code 999 by the number of the parameter to be changed.
The change checking can be made through the HMI or only reading the parameter content.
NOTE!
The Parameter Content should be maintained during 15.0 ms by the Master.
Only after this timea newvaluecanbe sent or anewparameter programmed.
6. Parameter Content to be changed, selected at pos. 5.
(Parameter Number to be changed)
The Value format to be set at this position should be that described in the
Manual, but this value should be written without the ten dot.
During the read/write process via Fieldbus the following variable indications in the Logical Status can occur:
Indications of the Logical Status variable:
E24 – Parameter changing only permitted when P004
0.
E25 – Caused by:
- Read Parameter inexistent, or
- Write Parameter inexistent, or
- Write attempt P000 = 10 via Fieldbus .
E26 – The desired content is out of permitted range.
E27 – Caused by: a) Thefunctionselected inthe Logical Control isnot enabled for theFieldbus, or b) The parameter write is read-only.
The error indication described above will be removed from the Logical
Status when the desired action is sent correctly.
The removal of the Error indication from E.L. described above, can also be realized by writing the Code 999 in Pos. 5. of the “Variables written in the converter”.
NOTE!
The errors E24, E25, E26 and E27 do not cause any change in the converter operation status.
HMI Displays:
E29 - Fieldbus connection is inactive.
This display appears when the physical connection of the converter to the
Master is interrupted. You can program in the Parameter P086 the action that the converter shall execute whenthe error E29is detected. When any key of the HMI is pressed, the E29 Error indicationisremoved from the display.
E30 - The Fieldbus board is inactive.
This error is displayed when:
1) P085 is programmed different than Inactive, without the respective
Fieldbus board at the connector XC5 of the CCW4 control board; or
2) The Fieldbus board is inserted, but it is defective; or
3) The Fieldbus board is inserted, but the standard programmed at P085 is not equal to the standard of the used board.
113
CHAPTER 8 - OPTIONS AND ACCESSORIES
You can program in the Parameter P86 the action that the converter shall execute when the error E30 is detected. When any key of the HMI is pressed, the E30 Error indication is removed from the display.

SERIAL COMMUNICATION
The variables are arranged in the memory of the Fieldbus device, starting at the address 00h, both for writing and reading process. The address differences are corrected by the protocol and by the communication board.
The way the variables are arranged at each address in the memory of the
Fieldbus depends on the equipment that is used as Master. For instance: in the PLC A the variables are arranged as High and Low, and in the PLC
B the variables are arranged as Low and High.

Interface Description
CHAPTER 8 - OPTIONS AND ACCESSORIES
WEG Protocol allows interconnection of up to 30 converters to one only
Master (PC, PLC, etc.) attributing to each converter one address (1 to 30) which is set in each converter. In addition to these 30 addresses, two other addresses are available for execution of special tasks.
Adress 0: any network inverter is inquired, independently of its address.
Only one inverter can be connected to the network (point-to-point) in order to prevent short- circuits in the line interface.
Adress 31: a control can be transmitted to all inverters in the network simultaneously, without acceptance recognition.

Resolution
8.2.3.3 Parameter Format
The physical connection between the inverters and the network master is performed according to one of the standards below: a. RS-232 (point-to-point, up to 10m); b. RS-485 (multipoint, galvanic isolation, up to 1000m).
NOTE!
For connecting the CTW-04 converter in network, you must use a level module converter RS-232 to RS-485.
In this case we have the connection of a master to an inverter (point-topoint). Data can be changed in a bi-directional way, but not simultaneous
(HALF DUPLEX).
The logical levels meet STANDARD EIA RS-232C that determines the use of balanced signals.
In this case, one wire is used for transmission (TX), one for reception (RX) and one for return (0V) .This configuration is a three-wire economy model.
The items of this chapter describe the protocol used for serial communication.
Parameters: are those existing in the inverters whose visualization or alteration is possible through the HMI interface.
Variables: are values that have specific inverter functions and that can be read and, in some cases, modified by the master.
Basic variables: are those that can be accessed only through the serial interface.

The parity monitoring is carried out according to DIN 66219 (even parity).
Two type of messages are used (by the master):
READ TELEGRAM: for checking the content of the converter variables;
WRITE TELEGRAM: for changing the content of the converter variables or for sending commands to the converter.
Note:
Transmission between two converters is not possible. The master has the access control to the bus bar.

The converters and the master test the telegram syntax.
Please find below the responses for the respective verified conditions:
Read Telegram:
no answer: telegram with wrong structure, control characters were wrong received or the converter address is wrong.
NAK: code corresponds to an inexistent variable or to a write only variable;
TEXT: with valid telegrams.
Write telegram:
no answer: telegram with wrong structure, control characters were wrong received or the converter address is wrong.
NAK: CODE corresponds to an inexistent variable, wrong BCC (Byte of CheCksum, a write only variable, VALout of range for the respective variables, operation parameter out of changing mode;
ACK: with valid telegrams.
The master should maintain wait time between the transmissions of two variables to the same converter which is compatible with the used converter.
8.2.3.6 Telegram Sequence The telegrams are processed by the converters within determined intervals.
Thus you must ensure a pause between the telegram transmission to the same converter which is longer than the sum of the times T proc

Error of fault code: byte-low
BYTE HIGH; indicates the logic converter status, where:
Logic Status:
EL15 EL14 EL13 EL12 EL11 EL10 EL9 EL8
EL8: 0 = disable by active ramp
1 = disable by inactive ramp
EL9: 0 = general disable by active ramp
1 = general disable by inactive ramp
EL10: 0 = counter-clockwise (CWW)
1 = clockwise
EL11: 0 = with fault
1 = without fault
EL12: 0 = with fault
1 = without fault
EL13: 0 = JOG+ inactive
1 = JOG+ active
EL14: 0 = JOG- inactive
1 = JOG- active
} converter enabled
EL8=EL9=1
BYTE LOW: indicates the Error or Fault Number in hexadecimal, if any.
Error or Fault Code:
Ex.: E00 to E06 or F02 to F08 or byte low will have 000 to 06 or
02 to 08 E22 to E27 or byte low will have 16H to 1BH.
The errors which are related to the serial communication will be reset automatically in the logic status variable after the first read or write operation without error. The indication in the display remains.

BYTE HIGH: mask for the desired action. The corresponding bit should be set to 1 for obtaining:
CL15 CL14 CL13 CL12 CL11 CL10 CL9 CL8
MSB LSB
CL8: 1 = ramp disable
CL9: 1 = general disable
CL10: 1 = direction of rotation
CL11: 1 = JOG+ active
CL12: 1 = JOG- active
CL13: = not used
CL14: = not used
CL15: 1 = Converter “RESET”

BYTE LOW: logic level of the intended action.
CL7 CL6 CL5 CL4 CL3 CL2 CL1 CL0
MSB LSB
CL0: 1 = enable
0 = ramp disable
CL1: 1 = enable
0 = general disable
CL2: 1 = clockwise direction of rotation
0 = counter-clockwise direction of rotation
CL3: 1 = JOG+ active
0 = JOG+ inactive
CL4: 1 = JOG- active
0 = JOG- inactive
CL5: not used
CL6: not used
CL7: transition from 0 to 1 in this bit causes converter “RESET”, when it is in some error or fault condition
Note:
External disable has priority over this disables;
For converter enable via serial communication, CL0=CL1=1 must be set and the external disable must be inactive;
When CL0=CL1=0 simultaneously , a general disable will occur;
The reset command does not act when Fault F02 or F05 is detected.

DIMENSIONING OF THE
CTW-04 CONVERTER
The CTW-04 converter dimensioning depends on several factors, such as, used DC-Motor, load cycle type, application, etc.
For the worst permitted 10 minute cycle, you should determine the converter rms, which cannot be higher than the rated armature DC current of the converter. In addition, the max. peak current during the load cycle cannot be higher than the rated armature current , multiplied by a 1.25
factor.
When the converter is operated at ambient temperature higher than 40°C and/or in altitude higher than 100m above sea level, set the DC-current as shown in the figure below:

The application requires the use of a converter able to operate in fourquadrants, with regenerative braking and able to support frequent reversals.
By considering the application and the current conditions, the required converter model will be the CTWA4.
For the converter dimensioning, please consider the 10 minutes cycle, where the load current is the highest.
In this case we will have:

Where: T1 = 2.5 minutes and T2 = 7.5 minutes. So Ief = 100A.
The rated DC current of the converter should be (40°C): I > 100A

For the chosen converter we will have I = 106 x 1.25 = 132.5 A.
DC max
The max. current shown in the figure 9.3. load cycle is 110A, lower than the Idc max of the converter.
The field current should be lower or equal to 18A;
The field supply voltage is 380Vac;
The armature voltage is 440Vac.
Thus the CTW -04 specified conv erter model should be:
CTWA40I06T44PFSZ.
