Hi all,
I have an ABB ACS 600 drive which I am having issues with.
The motor runs a platform down to a position then indexes back up to the start during the sequence.
The drive runs a 22KW motor with an encoder attached. Under normal operation I can run the motor in manual, forwards or reverse or start the auto sequence.
When I reset the circuit the motor drives straight away, in manual or auto without pressing any buttons. I'm not getting any inputs from the PLC to permit the inverter to drive and no faulty buttons.
Here's the thing, when the motor drives it drives the platform down. I decided to swap 2 phases from the output of the inverter and reboot the inverter to drive the motor back up to its starting position.
When I swap the phases, the motor does not drive at all and I am able to operate the motor in manual. I can raise and lower the platform, albeit the raise and lower button work opposite, but it can be operated.
I'm not asking for someone to fault find my initial issue but the swapping the phases has got me stumped.
Any help would be greatly appreciated.
