_ X _ _: Stop mode
0: Deceleration stop
In the case of deceleration stop, the inverter will gradually reduce the output frequency according to the
preset deceleration time until it stops.
1: Free stop
At stop, the inverter outputs zero frequency and clocks output signals, and the motor will stop in a free sliding
way according to inertia.
At free stop, if it is needed to restart the motor before the motor stops running completely, it is necessary to
appropriately configure the revolution tracking start function; Otherwise, it will leads to overcurrent or
overvoltage fault protection.
If the motor has not stopped completely in deceleration way, because of high load inertia of the field work and
short deceleration time, it is then applicable to start DC band-type braking control. See the instructions of the
parameter
F0.4.44
for details.
F0.4.39 Start frequency
Setting range: 0.0Hz~50.00Hz
Factory default: 0.50
F0.4.40 Start frequency hold time
Setting range: 0.00~10.00Sec.
Factory default: 0.0
The start frequency means the initial frequency when the inverter starts up, and is not limited by the lower
limiting frequency
F0.1.22
.
The start frequency holding time means the duration of operation at the start frequency, and can be set
according to actual needs. When it is set to 0, the start frequency is void.
For the system with high inertia, heavy load and high requirement of start torque, the start frequency can
effectively overcome the difficult of start, and the start frequency is also effective in each acceleration
process when the inverter switches between forward and reverse running.
