800w spindle - noise & controlling remotely

[Boyan Silyavski]

reasons for OL1 trip:

• The acceleration time ACC is too short. • Increase the acceleration time
• The DC braking amout is too large. • Reduce the DC braking amount and the DC braking time
• The V/F setting is improper. • Check the V/F parameter setting
• A restart signal is input to the rotating motor after a momentary stop, etc. • Use (auto-restart) and (ride-through control).
• The load is too large. • Use an inverter with a larger rating.


It should be 3 -• The V/F setting is improper

There are settings that affect other setting. Just to be sure check again
5.11 manual
Pt=0 ?

I start to wonder. Are your phases connected correctly and if there is a continuity in all of them. That crappy chinese connector could be making some bad connection for a second.
I remember now there was a time my VFD was tripping and i disassembled the whole machine. At the end it turned the crappy connector. Flex on the cable made a bad connection there. It took me 3 days / 10h per day to figure it

Ps.
check F400 if set to 0.
if not, this could be the problem.

If set to 0, read section 6.1? and try to autotune the motor, but separately from the vector control. Do not change Au2 from 0, just follow the instructions and check if trip will appear after 3 seconds, and what that trip will be.

The other cure if all this still dont work is to sit down. read the manual step by step and check everything. Cause this inverter can store various motors, can be controlled in various ways, so there could be the problem.

At the end i believe it has something to do with the vector control, faulty spindle or bad connection on phase
