X1 — voltage supply

Connection for the main supply (power). Connector type: M12, 4-pin, L-coded, male

Suitable Nanotec cable: ZK-M12-4-...-...-LFF (not included in the scope of delivery)



Note: The integrated control is supplied by the logic supply (on X2/X3/X4), the connection of which is necessary for communication and for operation.

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 assignment

Pin Function Note
1 +UB

12…57.6 V DC

red (when using cable ZK-M12-4-...-...-LFF)

2 +UB

12…57.6 V DC

red/white (when using cable ZK-M12-4-...-...-LFF)

3 GND black (when using cable ZK-M12-4-...-...-LFF)
4 GND black/white (when using cable ZK-M12-4-...-...-LFF)
Note:
  • Damage to the electronics if the supply voltage is connected with reversed polarity!
  • Polarity reversal results in a short-circuit between supply voltage and GND (earth) via the power diode.
  • ► Observe the pin assignment.
  • ► Install a line protection device (fuse) in the supply line.

Permissible operating voltage

The maximum operating voltage is 57.6 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 CRS500JT-73-15RAA from VITROHM with 5 W continuous output).

The minimum operating voltage is 12 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 (PD6-EB…): 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.

Note:
  • There is a cross connection between pin 2 of X3/X4 and pin 12 of X2.
  • ► Never use different voltage sources for supplying the UB Logic via connections X3/X4 and X2.
Note:

The logic supply powers the electronics, the encoder and the communication interface.

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

Connecting an external encoder

You can connect an external encoder to the pins of the digital inputs, which you can assign to a control loop. See chapter Configuring the sensors and Assignment of the feedbacks to the control loops.

Incremental encoders are supported with or without index, single-ended or differential:

Pin Single-ended Differential
1 GND GND
2 A\ A
3 A B
4 B\ I
5 B
6 I\
7 I
Note:

You can connect 5 V encoders to the voltage output on pin 11 provided the required current does not exceed 250 mA.

For 24 V encoders, you must:

  • provide an external supply voltage
  • and set the corresponding bits in 3240h:06h to the value "1" to switch the level to 24 V.
