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 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 whenthe output is
shut off.
