of the fan drove by the motor axis will reduce, which will bring motor overheat. So please set the motor overheat protection current [F10.16] in the frequency

drive to be valid.

Motor cable is longer

While the motor cable is longer and the carrier frequency is higher, impacted by the leakage current, the heat relay maybe malfunction. To avoid it, please

reduce the carrier frequency or set higher detection value of the heat relay. Before enhance the detection value, do confirm whether there is other cause

for the motor overheat. Otherwise, there is danger.
