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.

Connections

  • Type: Phoenix Contact MCDN 1.5/ 8-G1-3.5 P26THR
  • Mating connector (included in scope of delivery): 2x Phönix Contact FMC 1.5/ 8-ST-3.5 (or equivalent)

Permissible operating voltage

Depending on the motor type, the maximum operating voltage is:

  • PD2-C4118L1804: 50.5 V DC.
  • PD2-CB42C048040: 50.5 V DC.
  • PD2-CB42M024040: 29 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 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.

X2 − Micro USB

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