Stopping Methods
This section explains methods of stopping the Inverter.
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 constant b1-03 to select the Inverter stopping method.

b1-03 Stopping method selection
Select stopping method when stop command is given.
0: Deceleration to stop
1: Coast to stop
2: DC braking stop (Stops faster than coast to stop, with-
out regenerative operation.)
3: Coast to stop with timer (Run commands are ignored
during deceleration time.)
0 to 3 0 No Q
b2-01
Zero speed level (DC injection
braking starting frequency)
Set the frequency at which the DC injection braking starts
in units of Hz when b1-03 is set to 0 (deceleration to stop).
DC injection braking starts from E1-09 when b2-01 <
E1-09.

b2-04 DC injection braking time at stop
Set the DC injection braking time at stop.
Use when stopping if rotations continue due to the
machines inertia.
Set to 0.00 to disable DC injection braking time at stop.
