F 30 I²t Error The average power
loss of the motor has
been greater than
the max. value
configured by
nominal motor
current, overload
factor and motor
time constant.
Refer to “I²t
Calculation” on
page 38 – Immediate
motor power
disable
– Let the motor cool down
– Acknowledge failure
– Check the configuration
of nominal motor
current, overload factor
and motor time
constant
– Reduce the average
load of the motor
