Enter the motor current rating (taken from the motor name plate).
The drive rated current is the 100% RMS output current value of the drive. This value
can be set to a lower value but not to a higher value than the drive rated current.
Enter the rated full load 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.
Enter the motor rated voltage (taken from the motor name plate).
This is the voltage applied to the motor at base frequency.

Motor rated current 0 to Drive rated current A Drive rating RW
Pr 06 Motor rated current must be set correctly to avoid a risk of fire in the event of a
motor overload.

07
Motor rated speed 0 to 9999 rpm Eur: 1500, USA: 1800 RW
A value of zero entered into Pr 07 means slip compensation is disabled.
NOTE
If the full load speed of the motor is above 9999rpm, enter a value of 0 in Pr 07. This will
disable slip compensation as values >9999 cannot be entered into this parameter.
NOTE
Slip compensation should be disabled when using the drive on a high inertia load.
