1 General
This bus description is to be used for the commissioning and integration of the drive into a field
bus system.
Technical data for the electrical connections of your drive can be found in the electrical connector
and pin assignment description on the website:
www.halstrup-walcher.de/technicaldocu
Please search for “PSD” and select your type, click on “Instruction manuals” and download the
“conntector and pin assignment” offered for your bus system.

2 Start-up
WARNING Risk of injury if used inappropriately.
The device must be installed by trained technical personnel.
WARNING Risk of burns due to hot drive.
The drive can become very hot during operation.
Allow the drive to cool before touching it.
WARNING Risk of crushing due to rotary movement.
Do not reach into the working area of the drive when it is still
turning.
The user/operator must ensure appropriate protective
measures are taken.
WARNING Incorrect assembly can lead to the destruction of the drive.
WARNING Check that the supply lines are not pinched or crushed.
Lay the supply lines according to the general and specific local
assembly regulations.
If the supply lines have not been delivered together with the
device, please select suitable cables for the application.
Do not operate the direct drive if the supply lines are
noticeably damaged.
WARNING Risk of injury. High contact voltages can occur in the case of
malfunctions.
This can be prevented by grounding.
ATTENTION The drive must be protected against excessive heating.
The user/operator must ensure appropriate protective measures are
taken.
ATTENTION Never apply force to the housing of the drive, e.g. for supporting
weight.

7100.006424_Bus description_PSD4xx_CA_J_ENG 62022-08-15
2.1 Set the device address
You can assign a unique device address using the address switch.
Note: If these address switches are set to 00, the address can be set via the CAN bus
with SDO #2026.
The device controls and status elements are located under the sealing plug. You will need a non-
conducting pointed object to adjust the switches (e.g. a screwdriver).
Set the tens and units on the respective address switches.
Turn the device off and on again or use the reset command via the control unit to accept the new
setting. The device address is now set and the setting is active.
Note: The delivery state is 00; the PSD4xx identifies itself using address 1 at the bus.
Note: If you set the address using the switches (i.e. switches set to > 0) you cannot
change this value using the CAN bus.
Note: The yellow LED shows the motor voltage status, the red and green LEDs show the
CANopen status.
Note: Always re-attach the protective cap after setting the address. This will prevent dust
and contaminants from entering the device.

Start-up
7100.006424_Bus description_PSD4xx_CA_J_ENG 7 2022-08-15
2.2 Set the baud rate
You can set the baud rate using the sliding switches S2-S4 (DIP switch 2-4).
The device controls and status elements are located under the sealing plug. You will need a non-
conducting pointed object to adjust the switches.
Please refer to the following table to find the correct baud rate settings and adjust the sliding
switches S2-S4 (DIP switch 2-4) accordingly:
Table: Baud rate:
S2 S3 S4 Description
OFF OFF OFF Set baud rate via bus (default = 500 kBaud)
ON OFF OFF 20 kBaud
OFF ON OFF 50 kBaud
ON ON OFF 125 kBaud
OFF OFF ON 250 kBaud
ON OFF ON 500 kBaud
OFF ON ON 800 kBaud
ON ON ON 1000 kBaud
Turn the device off and on again or use the reset command via the control unit to accept the new
setting.
Note:
Maximum bus length Baud rate
250 m 250 kBaud
100 m 500 kBaud

Start-up
7100.006424_Bus description_PSD4xx_CA_J_ENG 82022-08-15
Note: If the sliding switches S2-S4 are set to OFF, the baud rate is set via the CAN bus
with SDO #2027.
Note: If at least one sliding switch S2-S4 is ON, the baud rate cannot be changed via the
CAN bus.
2.3 CAN terminating resistor
You can use the sliding switch S1 (DIP switch 1) to set the CAN terminating resistor (120 Ω).
Note: For a line topology, the bus termination is at both ends of the network.
The device controls and status elements are located under the sealing plug. You will need a non-
conducting pointed object to adjust the switches (e.g. a screwdriver).
Please refer to the following table for the terminating resistor settings and adjust the sliding switch
S1 (DIP switch 1) accordingly:
S1 Description
OFF Deactivate the terminating resistor
ON Activate the terminating resistor

Start-up
7100.006424_Bus description_PSD4xx_CA_J_ENG 9 2022-08-15
2.4 Switch the device on
To turn on the PSD4xx, install the PSD in the correct position according to the assembly
instructions. You can find information about installing the drive as well as electrical connections
and pin assignments at the following link: www.halstrup-walcher.de/technicaldocu
Please search for “PSD” and select your type, click on “Instruction manuals” and download the
“conntector and pin assignment” offered for your bus system.
The PSD4xx must be grounded before the power supply cable is connected. The grounding cable
must be connected to the correct position on the PSD4xx and to the ground potential (e.g.
machine base).
Note: The positioning system should be connected to the machine base using the
shortest possible cable. The minimum wire cross-section of the grounding cable is
1.5 mm².
Once the PSD has been grounded, it can be connected to the power supply and the
communication interface. The drive is now ready for operation.

7100.006424_Bus description_PSD4xx_CA_J_ENG 10 2022-08-15
3 Description of CANopen
The CAN bus interface uses the CANopen protocol in accordance with CiA DS 301 Version 4.02:
-One transmit and one receive SDO per device
-One asynchronous transmit and receive PDO, active by default
-One heartbeat object every 500 ms
3.1 Status LEDs
The following LEDs are located under the sealing plug:
Green LED (gn) = RUN LED in accordance with CANopen:
Single flashes:
CAN stop
Continuous flashing:
CAN preoperational
Continuously illuminated: CAN operational
Red LED (rd) = ERROR LED in accordance with CANopen:
Single flashes: CAN-transmitter or -receiver has reached its warning limit
Double flashes: Guard event has occurred
Triple flashes:
Sync failure
Continuously illuminated:
CAN bus OFF
Yellow LED (ye) = Display actuator voltage:
Off:
Motor voltage too low or too high
On:
Motor voltage OK
Flashing at 0.5 Hz Motor voltage OK and drive in the delivery state (for parameter values
and axle positions)

Writing a “-5”:
Resets the drive (corresponds
to switching the control voltage
off and on again)
Writing a “-4”:
Resets all parameters to the
delivery states (CAN address
SDO #2026 to 1, baud rate
SDO #2027 to 500 kBaud),
without saving the parameters
in EEPROM, without a start-up
reference loop and without
positioning in the middle of the
measurement range.
Writing a “-3”:
Resets all parameters to the
delivery states (without
changing the CAN address and
baud rate), without saving the
parameters in EEPROM,
without a start-up reference
loop and without positioning in
the middle of the measurement
range.
Writing a “-2”:
Resets all parameters to the
delivery states (CAN address
SDO #2026 to 1, baud rate
SDO #2027 to 500 kBaud),
without saving the parameters
in EEPROM. The drive then
performs a start-up reference
loop and positions itself in the
middle of the measurement
range.

Writing a “-1”:
Resets all parameters to the
delivery states (without
changing the CAN address and
baud rate), without saving the
parameters in EEPROM. The
drive then performs a start-up
reference loop and positions
itself in the middle of the
measurement range.
Writing a “1”:
Saves the parameter in
EEPROM
Writing a “0”:
No action
Reading after booting:
0 Memory content correct
