Issue Number: 6
The rated current parameter must be set to the maximum continuous current of the motor (taken
from the name plate). The motor rated current is used in the following:
• Current limits
• Motor thermal overload protection
• Vector mode voltage control
• Slip compensation (see Enable Slip Compensation)
• Dynamic V/F control
Set to the rated speed of the motor (taken from the motor name plate). The motor rated speed is
used to calculate the correct slip speed for the motor.
The Rated Voltage (00.008) and the Rated Frequency (00.039) are used to define the voltage to
frequency characteristic applied to the motor. The Rated Frequency (00.039) is also used in
conjunction with the Motor Rated Speed (00.007) to calculate the rated slip for slip compensation.
Enter the motor rated power factor cos
ϕ (taken from the motor name plate).
The drive can measure the motor rated power factor by performing a rotating autotune (see Autotune
(Pr 00.038).
