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.

The following switching thresholds apply for the digital inputs:
| Max. Voltage | Switching thresholds | |

| On | Off | |
| 5 V | > approx. 3.6 V | < approx. 1 V |
| 24 V | > approx. 16 V | < approx. 4.5 V |

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.
