Stopping Methods
This
section explains methods of stopping the Inverter.

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

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.)

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

DC
injection braking time
at
stop
Sets
the DC injection braking time in seconds.
The
motor coasts to a stop after the deceleration
time
due to inertia. DC injection breaking stops
coasting.
The
value 0.00 disables DC injection.
