*The actual adjustment range changes based on the values in U.002 (Motor Poles)
and U.003 (Motor Nameplate Base Frequency):

In general, the value range for U.005 is:

U.003 x 120 x .900 to U.003 x 120 x .999
U.002 U.002

If the value is too close to the synchronous RPM, the drive may exhibit instability. This
value directly affects torque linearity and the maximum attainable horsepower.

If you change this parameter after performing self-tuning using parameter U.008, you
must repeat the self-tuning procedure.

U.005 Motor Nameplate RPM

This parameter
identifies the motor
rated RPM as it
appears on the motor
nameplate.

This parameter must
be set prior to
activating the torque
control self-tuning
procedure (U.008).

Parameter Range:

*

Default Setting:

Power Module-dependent, see Appendix C

Parameter Type:

Configurable

ATTENTION: The setting of parameters U.001 (Encoder PPR), U.002
(Motor Poles), U.003 (Motor Nameplate Base Frequency), U.005 (Motor
Nameplate RPM), and U.017 (Motor Top Speed) determines the motor
maximum speed. These parameters must be set by a qualified person
who understands the significance of setting them accurately. Failure to
observe this precaution could result in bodily injury.
