    NOTICE

    For encoders RK8M, EK8W, AK8H, AK8W, EK9Z and AK8Z on DR2C.. motors, a calibration process must be carried out for flawless operation. See Additional work for the RK8M encoder on the DR2C.. motor and Additional work for EK8W, AK8H, AK8W, EK9Z, and AK8Z encoders on the DR2C.. motor.
    Failure to calibrate results in greater motor losses and reduced torque. In the worst-case scenario, the motor will not run.
