What needs to be done to run a autodiagnostics or self test on an ATV66 or the ATV56 AC drive?

In the de-energized state the supply power connections must be removed from the L1, L2 & L3 drive power terminals. If there is a jumper from the drives CL1 control power terminal to the drives L1 power terminal it must be removed. If there is a jumper from the drives CL2 control power terminal to the drives L2 power terminal it must be removed. The L1 power supply must then be connected to CL1 and the L2 power supply must then be connected to CL2. With power applied to CL1 and CL2 only can run the autodiagnostic test in Menu 8 of the AC drive. If a DC Bus Too High message is seen on the keypad display when trying to run the autodiagnostics this could indicate that there is still power applied to the L1, L2 or L3 terminals of the drive causing the DC bus voltage to be greater than 22VDC.
