Additional work for EK8W, AK8H, AK8W, EK9Z, and AK8Z encoders on the DR2C.. motor

For the EK8W, AK8H, AK8W, EK9Z, and AK8Z encoders, perform the following steps after installing the encoder:

  • The motor is unloaded and the brake released. The rotor can freely align itself in the stator field.
  1. Supply the motor with direct current 60 – 80% I0 (for no more than 10 minutes) to perform an adjustment check (see the following table).
    • The rotor aligns in the field.
  2. In this rotor position, set the encoder angle to 0 via SEW-EURODRIVE’s inverter and the RS485 interface.
