COMMAND (FACTORY SETTING: 0.5s)
Upon removal of the FWD (REV) run command, the motor decelerates at
the decel rate determined by the time set to decel time 1 (n21) and DC
injection braking is applied immediately before stop. If the decel time is
short or the load inertia is large, overvohage (OV) fault may occur at
deceleration. In this case, increase the decel time or install a optional
braking resistor.
Braking torque : Without braking resistor : Approx. 20% torque of motor rating
With braking resistor: Approx. 150% torque of motor
rating
