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.

Description
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.)
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.
Set the DC injection braking current as a percentage, tak-
ing the Inverter rated current as 100%.
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.
