Caution:
The following combination of parameter setting should not be combined:
-P0610 = 1 and P0335 = 0 or 2 :
When P0335 = 0 or 2 the inverter cools the motor using a shaft mounted fan. If this is used in
conjunction with P0610 the cooling of the motor will be inefficient.
In essence, if the i2t calculation reduces the output frequency, then the shaft mounted fan will also reduce its cooling effect, the motor will then eventually overheat and trip.
-Exception:
Applications with variable torque the reduction of max. current leeds automatically to a reduction of the load / output current.
Notice:
Motors of series 1LA1 and 1LA8 have an internal fan. This internal motor fan must not be confused with the fan at the end of the motor shaft.
