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 second.
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.
