Derate
If either heatsink or control card temperature exceeds a programmed temperature limit, a warning
will be activated. If the temperature increases further, select whether the frequency converter
should trip (trip locked) or derate the output current.
Trip
[0]: The frequency converter will trip (trip locked) and generate an alarm. Power must be cycled
to reset the alarm, but will not allow restart of the motor until the heat sink temperature has dropped
below the alarm limit.
Derate
[1]: If the critical temperature is exceeded the output current will be reduced until the al-
lowable temperature has been reached.
