Application Notes
Fast
Brake
This method uses drive output reduction to stop the load.
1. On Stop, the drive output will decrease according to the programmed pattern from its
present value to zero at the rate determined by the programmed active [Decel Time x].
This is accomplished by lowering the output frequency below the motor speed where
regeneration will not occur. This causes excess energy to be lost in the motor.
2. The reduction in output can be limited by other drive factors such as bus or current
regulation.
3. When the output reaches very near zero, DC brake will automatically be used to
complete the stop then the output is shut off.
