FP5/GP5 Operation
Stopping Method (n004, Stopping Method)
This function selects the stopping method suitable for the particular application.
·Deceleration to Stop (n004 = “Ramp to STOP”)
Upon removal of the FWD (REV) run command, the motor decelerates at
a deceleration rate determined by the time set in deceleration time 1
(n019) and DC injection braking is applied immediately before when the
minimum output frequency (n016) is reached. If the deceleration time is
short or the load inertia is large, an overvoltage fault (OV) may occur dur-
ing deceleration. In this case, increase the deceleration time or install an
optional braking resistor .
Braking torque:w/o braking resistor, approx. 20% of motor rated torque
w/ braking resistor, approx. 150% of motor rated torque
·Coast to Stop (n004 = “Coast to STOP”)
Upon removal of the FWD (REV) run command, the motor coasts.
