Parameter Details
Set main power supply alarm detection time.
The main power supply OFF detection will be disabled if this is set to 2,000.
Explanation of Set Values
Set the operation to be performed after stopping or during deceleration when any protective
function of the drive operates and an alarm occurs.
The dynamic brake is designed only for emergency stopping. Design the system to stop within
about ten minutes after the dynamic brake operates.
*1. The error counter is cleared when an alarm is reset.
*2. Operations A and B indicate whether immediate stop takes place upon alarm generation. If an
immediate stop alarm is generated, immediate stop in operation A is executed.
If an alarm that does not support immediate stop is generated, immediate stop in operation B will take
place.
*3. Decelerating is the time between when the motor is running and when the motor speed reaches 30 r/
min or less. Once the motor reaches 30 r/min or less and moves to the after-stop status, subsequent
operation is based on the after-stop status regardless of the motor speed.
