Using v20 to run small fan (1/2 HP) using two speeds, 50% and 100%. After sometime, more than 2 hrs, drive will fault with f2 error. It will switch speeds fine, ramp up and down is 10 seconds as default in application macro. I'm not using any braking resistor, is it necessary for fan application? I could change ramp down to disable, I did this on another drive with no effect on f2.
I actually have two drives like this, other one I wrote some auto fault reset code in the PLC, but second unit is not wired to PLC. I know the incoming power is good, usually around 475 volts, so under voltage if anything.
Suggestions? I could wire it to the PLC and use the fault reset function, but it seems like that's avoiding the problem.
