Q : How to check whether low speed running of the elevator is successful?
A: 1) Inspect start-up at least 20 times and EC160 does not alarm any fault; if abnormal, handle the fault according to Appendix-EC160 Fault code.
2) Inspect up and down running and check whether in accordance with the running direction of the motor; if abnormal, change P0.08.
3) Inspect up and down running, check whether the output current of A system control-[3]drive state exceeds 1A and the output current is the same (synchronous motor); if abnormal, redo motor autotuning or check whether the brake can open normally or the brake clearance is too small.
4) Inspect up and down running and check whether the output current of A system control-[3]drive state is the same (asynchronous motor); if abnormal, redo motor autotuning or check whether the parameter of running comfortability is proper.
5) Inspect up and down running and check whether the reference speed and feedback speed of A system control-[3]drive state are proper (±5%); if abnormal, check whether the parameters of the motor are correct.
6) Inspect up and down running and check whether the height changes in accordance with the running direction in A system control-[3]drive state; if abnormal, change P3.11.
