Reconnect the power.
(Note 1) Code 41: The ALM lamp will turn on if a drop in motor voltage is detected.
(Note 2) Difference in alarm reset method from the PLC
 If the PIO pattern is “0: [Conventional],” actuate an emergency stop or cut off the motor drive power
first, and then input the start signal (CSTR) for at least 6 msec.
Thereafter, cancel the emergency stop or connect the motor drive power.
(This operation is effective on software version AD000007 or later supporting the absolute
specification.)
 If the PIO pattern is other than “0: [Conventional],” input the reset signal (RES) for at least 6
msec.
Note: Reset each alarm after identifying and removing the cause. If the cause of the alarm cannot be
removed or when the alarm cannot be reset after removing the cause, please contact IAI.
If the same error occurs again after resetting the alarm, it means the cause of the alarm has
not been removed.
