Selecting the Stopping Method when a Stop Command is Sent

There are four methods of stopping the Drive when a stop command is sent:

Deceleration to stop

Coast to stop

DC braking stop

Coast to stop with timer

Set parameter b1-03 to select the Drive stopping method. A DC braking stop and coasting to a stop with a
timer cannot be set for flux vector control.

frequency set in E1-09.

0: Operates according to frequency

reference (E1-09 is disabled).

1: Output shuts off (coast to stop if less

than E1-09).

2: Operates according to E1-09

(frequency reference set to E1-09).

3: Zero speed (frequency reference

becomes zero when less than E1-09).
