Stopping Methods
Selecting the Stopping Method when a Stop Command is Input
There are four methods of stopping the Inverter when a stop command is input:
•
Deceleration to stop
•
Coast to stop
•
DC braking stop
•
Coast to stop with timer
Set parameter b1-03 to select the Inverter stopping method.

0: Deceleration to stop
1: Coast to stop
2: DC braking stop (Stops faster than coast
to stop, without regenerative operation.)
3: Coast to stop with timer (Run commands
are ignored during deceleration time.)

Stopping Method
b2-01
Zero speed level (DC
injection braking start-
ing frequency)
Set the frequency to start the DC injection
braking in units of Hz when deceleration to
stop is selected.
DC injection braking starts from E1-09
when b2-01 < E1-09.
