Invt CHV190-015G-4 Инструкция по эксплуатации онлайн [165/242] 471531

CHV190 series special inverter for crane

- 164 -

Close loop running sequential brief:

1. Inverter receives the UP/DOWN running and magnetic excitation from controller,

Inverter outputs contactor switch on control instruction and then receive its feedback

instruction after delay time T1, T1 deponds on contactor hardware delay time. P8.08

definite maximum delay time. If T1>P8.08, the inverter will show fault and stop.

2. After the motor running and inverter magnetic excitation running T2, inverter output

excitation finish signal and start to zero speed running for T3, then the inverter output

brake switch on signal and provides a pretorque for motor.

3. After the time T4, inverter receive brake feedback signals to confirm the brake is switch

on, meanwhile, inverter start to accelerate according to S curve. T4 deponds on the brake

switching time. P8.07 definite maximum delay time. If T4>P8.07, the inverter will show

fault and stop.

4. After the controller cutting off speed instruction, inverter begins to decelerate according

to S curve, when the speed reaches the threshold of stopping brake frequency. Inverter

will output brake instruction after delay time T5, which demand controller cut off

UP/DOWN command and output zero speed running signal.

5. The controller receives stopping command after T6, then inverter will stop after inverter

T7. meanwhile, inverter should output contactor loose and motor stop signal until the

complete process finish.

Notice: the logical is suitable for contactor and brake signal of inverter, If

itisnotused for controlling brake, Running 1 and brake switch on signal can be used

for brake control of inverter.
