Connector X2 – encoder/Hall sensor

Note:

Two types of encoder/Hall sensor are supported:

  1. Encoder/Hall sensor with 5 V supply voltage. In this case, nothing is to be connected to connector X9 ; object 2059h must be set to the value "0" (factory setting).
  2. Encoder/Hall sensor with 24 V supply voltage. In this case, you must connect a voltage of 24 V DC to connector X9 (see Connector X9 – voltage supply for encoder/Hall sensor, external logic supply) and set object 2059h to the value "1".

Pin 1 and pin 2 are marked in the figure.

Connector X6 – 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

Pin 1 is marked with an asterisk "*".

Permissible operating voltage

Depending on the version, the maximum operating voltage is:

If the input voltage of the controller exceeds this threshold value, the motor is switched off and an error triggered. The integrated ballast circuit (25 W power) is activated above:

  • N5-1 (low current): 75 V DC
  • N5-2 (high current) and up to hardware version w007: 50.5 V DC
  • N5-2 (high current) and hardware version w007b and higher: 57.5 V DC.

The minimum operating voltage is 10 V DC. If the input voltage of the controller falls below this threshold value, 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).

Connector X7 - EtherCAT IN

Pin 1 is marked with an asterisk "*".

Connector X8 – EtherCAT OUT

Pin 1 is marked with an asterisk "*".

Connector X9 – voltage supply for encoder/Hall sensor, external logic supply

Functionality

The voltage supply at X9 must be connected under one of the following conditions:
  1. A 24 V encoder is used. In this case, a voltage of 24 V DC must be connected to X9 and bit 0 in object 2059h set to the value "1".
  2. A logic voltage supply is necessary for the controller to ensure continued access to the following functions should the power supply be lost at connector X6 (see "Connector X6 – voltage supply"):
    • Logical functionality of the controller
    • Controller communication
    • Encoder
    Note: The windings of the motor are not supplied by the logic supply.
    In this case, a voltage of 24 V DC must be connected to X9. With a 24 V encoder, bit 0 in object 2059h must be set to the value "1". In the case of a 5 V encoder, bit 0 in object 2059h is to be set to the value "0".
