U.003 Motor Nameplate Base Frequency
This parameter
identifies the motor
base frequency as it
appears on the motor
nameplate.
This parameter must
be entered before
parameter U.005
(Motor Nameplate
RPM). Parameter
U.005 is limited by
the motor base
frequency.
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.
Important: Verify that the value in U.017 is correct if U.003 is changed.
Parameter Range: 15.0 to 240.0 Hz
Default Setting: 60.0
Parameter Type: Configurable

U.004 Motor Nameplate Amps
This parameter
identifies the motor
rated amps as it
appears on the motor
nameplate.
ATTENTION: This parameter must not exceed the rated amps found
on the motor nameplate. Overcurrent or excess heating of the motor
could result if rated amps are exceeded. Failure to observe this
precaution could result in damage to, or destruction of, the equipment.
If you change this parameter after performing self-tuning using parameter U.008,
you must repeat the self-tuning procedure.
Note that the Power Module's Current Limit value (P.005) scales to the value
entered in U.004 to assure drive and motor coordination.
Parameter Range: Power Module-dependent
Default Setting: Power Module-dependent, see Appendix C
Parameter Type: Configurable
