22 Braking operation l Increase deceleration times
l For operation with an external
brake resistor:
– Check dimensioning,
connection and supply cable of
the brake resistor
– Increase deceleration times
Earth leakage at motor end Check motor supply cable and motor
for earth fault (disconnect motor
from the inverter)
