Stopping Methods
This section explains methods of stopping the Inverter.
Selecting the Stopping Method when a Stop Command is Sent
There are four methods of stopping the Inverter when a Stop Command is sent:
• Deceleration to stop
• Coast to stop
• DC braking stop
• Coast to stop with timer
Set constant b1-03 to select the Inverter stopping method. A DC braking stop and coasting to a stop with a
timer cannot be set for flux vector control.

Used to set the method of operation
when the frequency reference input
is less than the minimum output fre-
quency (E1-09).
0: Run at frequency reference (E1-09
not effective).
1: STOP (Frequencies below E1-09
in the coast to stop state.)
2: Run at min. frequency.

Used to set the frequency which starts
DC injection braking in units of Hz
when deceleration to stop is selected.
When b2-01 is less than E1-09, E1-09
becomes the DC injection braking
starting frequency.
