Coast to a Stop
Example when Acceleration/Deceleration Time 1 is selected
* Changing the frequency reference while running
Upon termination of the FWD (REV) Run Command, the motor
starts coasting.
Applying DC Injection Braking
DC Injection Braking Current (n089)
Sets the DC injection braking current in units of 1%. (Inverter rated cur-
rent=100%)
DC Injection Braking Time at Stop (n090)
Sets the DC injection braking time at stopping in units of 0.1 s. When
the setting of n090 is 0, DC injection braking is not performed, but the
Inverter output is turned OFF when DC injection braking is started.
When coasting to a stop is specified in the Stopping Method Selection
(n005), DC injection braking is not applied when stopping.
Simple Positioning Control when Stopping
• If a sequence input terminal is used for a RUN/STOP sequence, sim-
ple positioning control when stopping can be used to reduce devia-
tion in the position where the motor stops after the Run Command is
started from the sequence input terminal.
