E5 User Manual
asynchronous motor lies in the handling of motor overload protection. Under low speed running,
ordinary motor has poor heat dissipation, so motor overload protection shall be derated at low
speed. Since fan-based heat dissipation of variable frequency motor is not affected by motor
speed, low-speed overload protection is not necessarily derated. Therefore, please set P30.00
to 0 when driving ordinary asynchronous motor so as to protect the motor reliably.
P30.01 Power rating of motor 1
P30.02 Rated voltage of motor 1
P30.03 Rated current of motor 1
P30.04 Rated frequency of motor 1
P30.05 Pole pairs of motor 1
P30.06 Rated speed of motor 1
The above motor motor parameters must be correctly set according to motor nameplate.
Please select the motor that suits the power class of the drive, or the control performance of the
drive will drop obviously.

After the autotuning of parameters of motor 1, above-noted parameters are automatically
updated and saved. Parameters P30.07~P30.09 are obtained through static autotuning, and
parameters P30.07~P30.14 are obtained through rotary autotuning. If above-noted parameters
