FF51 and switching between drivers
Our ACS 800 drive has start showing a fault, FF51 which is a fault with the line side of the converter
Problem is when I go into the options menu to switch to the line side driver, there is not an option. Normally you should be able to switch between 1 & 2 but its only showing the number one, it like the line side cant bet connected to, which means you can’t acknowledge the fault.
What could be causing this?
