X3 – voltage supply

Connection for the main supply. Type: M12, 5-pin, B-coded, male

Suitable Nanotec cable: ZK-M12-5-2M-1-B-S (not included in the scope of delivery)

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 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 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 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.

X4 – Inputs/outputs and external logic supply

Connection for the digital and analog inputs/outputs and the external logic supply. Type: M12, 12-pin, A-coded, male

Note:

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.

The following switching thresholds apply for inputs 1 to 6:
Max. Voltage Switching thresholds
Switching on Switching off
5 V > 4.09 V < 0.95 V
24 V > 14.74 V < 3.78 V
