X2 – digital inputs

Connection for the digital inputs.

2 Digital input 2 0/+24 V
3 Digital input 3 0/+24 V
4 -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
5 +Release (+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. 5 V / 24 V signal, switchable by means of software with object 3240h, 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. 5 V / 24 V signal, switchable by means of software with object 3240h, max. 1 MHz
9 Clock (+input 6)
10 GND
Note: All inputs for clock-direction can be switched together between 5 V and 24 V and also between single-ended and differential.
The following switching thresholds apply for inputs 1 to 3:

On Off
> approx. 16 V < approx. 4 V
The following switching thresholds apply for inputs 4 to 6 (pins 4 to 9):

If you set 3240h:07h to the value "1", three differential inputs are available on pins 4 to 9. Where:

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.

Connections

  • Type: Phoenix Contact MCV 1.5/ 2-G-3.5

Permissible operating voltage

The maximum operating voltage is 50.4 V DC for the stepper motors (PD4-C) and 25.2 V for the BLDC motors (PD4-CB). 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 Z32041412209K6C000 from Vishay with 3 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 (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).

Note:
  • 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.
