8.3.2 Shutdown mode
The frequency converter has three stop modes, which are deceleration stop, free stop and deceleration stop
+ DC braking. Set parameter F1.05 to select the stop mode of the inverter.

● Deceleration stop
Set F1.05=0, the inverter decelerates to stop. After the stop command is valid, the inverter reduces the
output frequency according to the deceleration time, and stops after the frequency drops to 0.

● free stop
Set F1.05=1, the inverter coasts to stop. After the stop command is valid, the frequency converter stops
output immediately, and the motor stops freely according to the mechanical inertia.
