What to Do
Check motor parameter settings (parameter
group 99 START-UP DATA)
Ensure that ID run has been completed
successfully.
Check panel connection (see appropriate
hardware manual).
Check control panel connector.
Replace control panel in mounting platform.
Check Fault Function parameters.
Check DriveWindow connection.
Switch control board power off and on again.
Reload firmware to control board.
Replace control board.
Check that INT board power cable is
connected.
Check that POW board is working correctly.
Replace INT board.
Check that INT board power cable is
connected.
Check that POW board is working correctly.
Replace INT board.
Check fibre optic cables or galvanic link. With
frame sizes R2-R6 link is galvanic.
If RMIO is powered from external supply,
ensure that supply is on. See parameter 16.09.
Check connection from inverter module Main
Circuit Interface Board, INT to PPCC
Branching Unit, PBU. (Inverter module 1 is
connected to PBU INT1 etc.)
Check motor cables.
Check setting of parameter 16.01. Switch on
signal or check wiring of selected source.
Check motor and motor cable.
Check power semiconductors (IGBTs) of
inverter module.
Check motor and motor cable.
Check there are no power factor correction
capacitors or surge absorbers in motor cable.
