Connector X1 – voltage supply, inputs and outputs

Voltage source

The operating or supply voltage supplies a battery, a transformer with rectification and filtering, or a switching power supply.

Note:
  • EMC: For a DC power supply line longer than 30 m or when using the motor on a DC bus, additional interference-suppression and protection measures are necessary.
  • An EMI filter is to be inserted in the DC supply line as close as possible to the controller/motor.
  • Long data or supply lines are to be routed through ferrites.

Permissible operating voltage

Depending on motor type, the operating voltage is:
  • PD2-C4118X1404-E-08: 51.5 V DC.
  • PD2-C4118L1804-E-08: 51.5 V DC.
  • PD2-CB42C048040-E-08: 51.5 V DC.
  • PD2-CB42M024040-E-08: 30 V DC.

The minimum operating voltage is 10 V DC. If the input voltage of the controller falls below this threshold value, the motor is switched off and an error triggered.

A charging capacitor of at least 4700 µF / 50 V must be connected to the supply voltage to avoid exceeding the permissible operating voltage (e.g., during braking).

Connector X2 – CANopen IN and external logic supply

PIN Function Note
1 +UB Logic 24 V DC input, external logic supply for communication, input voltage, current consumption approx. 35 mA
2 CAN+  
3 CAN-  
4 GND  
Note: The windings of the motor are not supplied by the logic supply.

Connector X3 – CANopen OUT and external logic supply

PIN Function Note
1 +UB Logic 24 V DC input, external logic supply for communication, input voltage, current consumption approx. 35 mA
2 CAN+  
3 CAN-  
4 GND  
Note: The windings of the motor are not supplied by the logic supply.

Switch S1 – 120 ohm termination resistor

This DIP switch switches the termination of 120 Ω between CAN+ and CAN- of the CAN bus on or off. The "up" switch position switches termination on (factory setting).

Switch S2 – CANopen node-ID and baud rate

Hex coding switch for setting the CANopen node-ID and baud rate. See chapter Setting node-ID and baud rate.
