Unit utilization
If "P860/P861 PWM frequency 1/2" > 4 kHz is set in the VFC operating modes and
"P862/P863 PWM fix 1/2" = OFF, the inverter automatically reduces the PWM frequency
in the event of a unit overload. In the CFC and SERVO operating modes, the PWM fre-
quency remains at the same setting and the inverter does not reduce the PWM frequen-
cy in the event of a unit overload. If the inverter is subjected to a higher than permitted
load, it issues the fault message "F44 Unit utilization" and switches off immediately.
Temperature con-
trolled fan The fans of the power section heat sink are subject to temperature-control. The fan is
not switched on until a heat sink temperature of
ϑ
= 45 °C is exceeded.
