  1. If this alarm is issued during spindle synchronization
    1. If the activation (SFR, SRV) of the motor on one side is turned off then back on the in the spindle synchronization mode, the spindle motor is accelerated to correct a position error built up during the period, thus causing this alarm. Modify the ladder so that SFR and SRV are not turned off in the spindle synchronization mode.
  2. If this alarm is issued while the motor is stopped
    1. The connection cable of the spindle sensor is faulty. Check if the cable of the spindle sensor built into the motor (BZ sensor when a built-in motor is used) is disconnected, and replace the cable as required.
    2. The spindle sensor built into the motor is not adjusted correctly. Adjust the sensor according to Subsection 4.3.4 of Part I.
