>+60°C • Allow controller to cool and ensure better
ventilation
• Check ambient temperature
Heat sink very dirty Clean heat sink
Impermissibly high currents or too
frequent and too long acceleration
• Check drive selection
• Check load, if necessary, replace defective
bearings

53 PTC monitoring (TRIP) Motor too hot because of excessive
current, or acceleration is too frequent
and too long
Check drive dimensioning

Braking operation • Prolong deceleration t imes.
• For operation with brake transistor:
– Check the selection and connection of the
brake resistor
– Increase the deceleration times
Earth leakage on the motor side Check motor cable and motor for earth fault
(disconnect motor from inverter)
