Parameter 14-22 Operation Mode
is
automatically set to normal operation.
Carry out a power cycle to start up in
normal operation after a control card
test.
If the test is OK
LCP readout: Control card OK.
Disconnect the mains supply and remove the
test plug. The green indicator light on the
control card lights up.
If the test fails
LCP readout: Control card I/O failure.
Replace the frequency converter or control
