X1 – voltage supply
Voltage source
The operating or supply voltage supplies a battery, a transformer with rectification and filtering, or a switching power supply.
- 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
The maximum operating voltage is 50.4 V DC. If the input voltage of the controller exceeds the threshold value set in 2034h, the motor is switched off and an error triggered. Above the response threshold set in 4021h:02h, the integrated ballast circuit is activated (wirewound resistor CR257-05T15R from VITROHM with 5 W continuous output).
The minimum operating voltage is 11.4 V DC. If the input voltage of the controller falls below 10 V, 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).
- Damage to the controller and/or its power supply due to excitation voltage of the motor!
- Voltage peaks during operation may damage the controller and possibly its power supply.
- ► Install suitable circuits (e.g., charging capacitor) that reduce voltage peaks.
- ► With BLDC motors: Select a voltage source that corresponds to the rated voltage of the respective motor as specified in the motor data sheet.
- ► Use a power supply with protection circuit to protect against overvoltage.

You can activate the alternative function of the digital inputs, which is used for the special drive modes. See chapter Special drive modes (clock-direction and analog speed).
If you set 3240h:07h to the value "1", three differential inputs are available instead of six single-ended inputs. Where:
| Switching on | Switching off |
|---|---|
| Voltage at input pin+ against GND > switch-on threshold | Voltage at input pin- against GND > switch-on threshold |
The following table shows all possible combinations:

X3 − Micro USB
A cable of type "micro USB" is needed for this USB connection.
X4 and X5 − CANopen IN/OUT
Type: RJ45, vertical, THT
Both connectors are configured identically according to the following table.
| Pin | Function | Note |
|---|---|---|
| 1 | CAN_H | CAN-High |
| 2 | CAN_L | CAN-Low |
| 3 | CAN GND | Internally connected with pin 7 |

Should the main supply fail, the logic supply keeps the electronics, the encoder and the communication interface in operation.
The windings of the motor are not supplied by the logic supply.
S1 – 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.
The value of this switch is added to the value of switch S2; this switch thereby sets the 1s place.
The same switch can also be used to select one of the special drive modes and switch between open and closed loop. See chapter Special drive modes (clock-direction and analog speed).
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.
The value of this switch is multiplied by 16 and added to the value of switch S1; this switch thereby sets the 16s place.

Example |
|
| Switch S2 is set to the value 1h, switch S1 to the value Fh; the result is the value 1Fh. | |
S3 – 120 ohm termination resistor
Switches the termination of 120 Ω between CAN_H and CAN_L of the CAN bus on or off (see X4 and X5 − CANopen IN/OUT).
