X1 − voltage supply

Connection for the main supply. Type: M8, 3-pin, A-coded, male

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.

Pin Function Note

  • PD2-C: 12-48 V, ±5%
  • PD2-CB: 12-24 V, ±5%
3 GND
4 n.c.

Permissible operating voltage

The maximum operating voltage is 50.5 V DC for the stepper motors (PD2-C) and 29 V DC for the BLDC motors (PD2-CB). If the input voltage of the controller exceeds 51.5 V or 30 V, the motor is switched off and an error triggered. Above 51.5 V DC, the integrated ballast circuit (3 W power) is activated.

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 (approx. 1000 µF per ampere rated current) must be connected in parallel to the supply voltage to avoid exceeding the permissible operating voltage (e.g., during braking).

X2 – digital inputs and outputs

X3 – analog input and digital inputs

Connection for inputs and outputs. Type: M8, 8-pin, A-coded, male

Connections

Pin Function Note
1 GND
2 Analog input 10 bit, 0-10 V or 0-20 mA, switchable by means of software
3 -Release (-input 4) The default setting for this input combination is "single-ended"; this means that the "-Release" input is deactivated, only "+Release" against GND is active. 5 V / 24 V signal, switchable by means of software with object 3240h, max. 1 MHz
4 +Release (+input 4)
5 –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. 5 V / 24 V signal, switchable by means of software with object 3240h, max. 1 MHz
6 Direction (+input 5)
7 –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. 5 V / 24 V signal, switchable by means of software with object 3240h, max. 1 MHz
8 Clock (+input 6)
The following switching thresholds apply for inputs 4 to 6 (PINs 3 to 8):
Type Max. Voltage Switching thresholds
Safe switch on Safe switch off
differential 5 V > 2.6 V < 1.8 V
24 V > 9.4 V <7.5 V
single-ended 5 V > 2.6 V < 1.8 V
24 V > 9.4 V <7.5 V

X4 − Mini USB

A cable of type "mini USB" is needed for this USB connection.

S1 – hex coding switch for the special drive modes (clock-direction and analog speed)

You can use this switch to select one of the special drive modes.
