Converter module temperature is excessive. Check ambient temperature. If it exceeds
40°C, ensure that load current does not
exceed derated load capacity of drive. See
appropriate hardware manual.
Check that ambient temperature setting is
correct (parameter
95.10 ).
Check converter module cooling air flow and
fan operation.
Cabinet installation: Check cabinet air inlet
filters. Change when necessary. See
appropriate hardware manual.
Modules installed in cabinet by user: Check
that cooling air circulation in cabinet has been
prevented with air baffles. See module
installation instructions.
Check inside of cabinet and heatsink of
converter module for dust pick-up. Clean when
necessary.
Reset and restart after problem is solved and
let converter module cool down.

Communication error on control board,
channel CH1
Electromagnetic interference Check connections of fibre optic cables on
channel CH1.
Check all I/O modules (if present) connected to
channel CH1.
Check for proper earthing of equipment. Check
for highly emissive components nearby.

One of motor phases is lost due to fault in
motor, motor cable, thermal relay (if used) or
internal fault. Check motor and motor cable.
Check thermal relay (if used).
Check Fault Function parameters. Disable this
protection.

Motor temperature is too high (or appears to be
too high) due to excessive load, insufficient
motor power, inadequate cooling or incorrect
start-up data. Check motor ratings and load.
Check start-up data.
Check Fault Function parameters.
