Description
Deceleration to stop
Coast to stop
• Deceleration to stop (n04 =0)
* When frequency reference is changed during running.
Upon removal of the FWD (REV) run command, the motor decelerates at the decel rate determined by the time set to decel time 1 (n17) and DC injection braking is applied immediately before stop. DC injection braking is also applied when the motor decelerates by setting the frequency reference lower than minimum output frequency while the(n14) with FWD (REV) run command remains ON.
If the decel time is short or the load inertia is large, an over voltage (OV) fault may occur during deceleration. In this case, increase the decel time.

• Coast to stop (n04=1)
* When frequency reference is changed during running.
Upon removal of the FWD (REV) run command, the motor starts coasting.
Applying DC injection braking
• DC injection braking current (n52)
Sets DC injection braking current level in units of 1%. (Inverter rated current=100%)
• DC injection braking time at stop (n53)
Sets the DC injection braking time at stopping in units of 0.1 second. When the setting of n53 is 0, DC injection braking is not performed but inverter output is shut
OFF at the timing of DC injection braking start.
When coast to a stop is selected as the stopping method selection (n04), DC injection braking at stop does not operate.
