Stopping Methods
This section explains methods of stopping the Drive.
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.

Selection
Operation method when frequency
reference is less than minimum output
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).

Frequency
Sets the frequency at which DC injection
braking starts when ramp to stop
(b1-03 = 0) is selected. If b2-01< E1-09,
DC Injection braking starts at E1-09.
Note: Zero Speed restrictions are active
in Flux Vector Mode.
