Connector X2 – digital inputs
Connection for the digital inputs.
Switching between 24 V (3240h:06="1") and 5 V (3240h:06="0") is performed via object 3240h as is switching from "single-ended" (3240h:07="0") to "differential" (3240h:07="1").
| Pin | Function | Note |
|---|---|---|
| 1 | Input 1 | Max. 24 V, not switchable |
| 2 | Input 2 | Max. 24 V, not switchable |
| 3 | Input 3 | Max. 24 V, not switchable |
| 4 | -Enable (-input 4) | The default setting for this input combination is "single-ended"; this means that the "-Enable" input is deactivated, only "+Enable" against GND is active. Max. 5 V or 24 V, "single-ended" or "differential", max. 1 MHz |
| 5 | +Enable (+input 4) | |
| 6 | –Direction (–input 5) | The default setting for this input combination is "single-ended"; this means that the "-Direction" input is deactivated, only "+Direction" against GND is active. Max. 5 V or 24 V, "single-ended" or "differential", max. 1 MHz |
| 7 | +Direction (+input 5) | |
| 8 | –Clock (–input 6) | The default setting for this input combination is "single-ended"; this means that the "-Clock" input is deactivated, only "+Clock" against GND is active. Max. 5 V or 24 V, "single-ended" or "differential", max. 1 MHz |
| 9 | +Clock (+input 6) | |
| 10 | GND |
The following switching thresholds apply for inputs 1 to 3:

Connector X3 - voltage supply
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
The maximum operating voltage is:
- 30 V DC for BLDC motors (PD4-CB). Above 29 V, the integrated ballast circuit (3 W power) is activated.
- 51.5 V DC for stepper motors (PD4-C). Above 50.5 V, the integrated ballast circuit (3 W power) is activated.
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).
