MOTOR 1 TEMP Measured motor temperature has exceeded
fault limit set by parameter 35.03.

MOTOR 2 TEMP Measured motor temperature has exceeded
fault limit set by parameter 35.06.

NO MOT DATA Motor data is not given or motor data does not
match with inverter data.

What to Do
Check motor ratings and load.
Check start-up data.
Check Fault Function parameters.
Check value of fault limit.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.

Check motor data parameters
99.05...99.09.
Check motor load.
Check acceleration time.
Check motor and motor cable (including
phasing).
Check encoder cable (including phasing).
Check motor nominal values from group
START-UP DATA to confirm that motor model
is correct.
Check that there are no power factor correction
or surge absorbers in motor cable.
Check motor load.
Check acceleration time.
Check motor and motor cable (including
phasing).
Check that there are no power factor correction
capacitors or surge absorbers in motor cable.
Check encoder cable (including phasing).
Check minimum/maximum speed settings.
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and resistor(s).
