Stop Method
Factory Setting: 00
Settings 00 STOP: ramp to stop E.F.: coast to stop
01 STOP: coast to stop E.F.: coast to stop
02 STOP: ramp to stop E.F.: ramp to stop
03 STOP: coast to stop E.F.: ramp to stop
The parameter determines how the motor is stopped when the AC motor drive receives a valid stop
command or detects External Fault.
1. Ramp: the AC motor drive decelerates to Minimum Output Frequency (Pr.01-05) according to the
deceleration time and then stops.
2. Coast: the AC motor drive stops the output instantly upon command, and the motor free runs until it
comes to a complete standstill.
3. The motor stop method is usually determined by the characteristics of the motor load and how frequently
it is stopped.
