CHV180 series frequency inverter special for elevator Appendix A
.118.
The time sequence:
The running time sequence is the same as Multi-step Speed’s on the whole. For
detailed description, please refer to Figure A.2.
Note:
1) The s-curve of inner inverter is invalid with analog quantity speed tracking
running mode.The run s-curve of elevator is generated by external controller.
The adjustment of P5.17 or P5.22 will influence the input sensitivity of analog
quantity.
2) If the change rate of analog quantity is too large it will cause the mutation of
running frequency which may result in the over-current or over-voltage occur.
A.2.3 Overhaul running
The wiring diagram of overhaul run mode is as follow:
