MEMO
If alarms occur consecutively within a period five times longer than the time set in

alarm code. When a retry is made, only the alarm code which occurred the first time
is stored.
When an alarm is reset at a retry made by the retry function, the accumulated data
of the electronic overcurrent protection and others are not cleared.
CAUTION
When you have set the retry function, stay away from the motor and machine. The
motor will start suddenly while it is at an alarm occurrence stop.
