Error and Maintenance
*1. An emergency stop means that there is an error causing an immediate stop when the Stop Selection
for Alarm Detection (Pn510) is set to a value between 4 and 7. Refer to the description about the Stop
Selection for Alarm Detection (Pn510) in “8-6 Extended parameters”.
*2. The alarm is not reset for 10 seconds once it occurs.
*3. The alarm cannot be reset unless the absolute value is cleared.
Note 1. If an unresettable alarm occurs, remove the error factor, cut off the control power to reset the
alarm.
2. If a resettable alarm occurs, reset the alarm via MECHATROLINK-II communications or on the
CX-Drive.
3. Any displays such as hh, , and HH on the error number mean internal malfunction on the MPU.
Cut off the power immediately when you encounter such a case.
