White Electric | Automatic Single Socket Outlet, 250VAC, 10A, 1 Pole

Issue:
OCA fault on ATV21/ATV212 drives?

Product line:
Altivar 212, ATV212, S-Flex

Environment:
All models, all serial numbers.

Cause:
Overcurrent during start-up or ground fault

Resolution:
OCA – short-circuit detected in drive output inverter stage during motor startup

Check that Line and Load cables are connected to the proper terminals.  Line cables go to R/L1, S/L2 and T/L3.  Load or motor cables go to U/T1, V/T2 and W/T3. 

Disconnect the motor leads from the drive.  Using a 1000V Megger, check the motor and motor leads for shorts or ground fault.

Try a voltage balance test.  With the motor leads still disconnected, set parameter F605 to 0 (disable Output Phase Failure).  Run the drive at 20Hz, 40Hz and 60Hz.  At each speed measure the line to line output voltages to see if they are balanced.
Don't forget to reset F605 to it's previous value after testing has been completed.

If line output voltages are measured balance at 20Hz, 40Hz, 60Hz.  Then, motor is needed to check with a 1000V Megger to see if the motor is bad.

Push Buttons and Operator Interface

Resolution:
Standard operators will be keyed alike with a Ronis 455 key. Other keys changes can be obtained by adding the proper suffix to the part number.
Example: ZB4BG3 12 will give a ZB4BG3 with a 421E key. Here are some standard key changes. Other key changes are available. Suggest checking the Q2C profiles for other key changes.
Add suffix 12 for 421E key.
Add suffix 10 for 458A key.
Add suffix 14 for 520E key.
Add suffix 20 for 3131A key.
