.

Important: Verify that the value in U.017 is correct if U.003 is changed.

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.

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.

Parameter Range:

15.0 to 240.0 Hz

Default Setting:

60.0

Parameter Type:

Configurable

Refer also to parameters:

U.002 Motor Poles
U.005 Motor Nameplate RPM

!

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.

U.004 Motor Nameplate Amps

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

Parameter Range:

Power Module-dependent

Default Setting:

Power Module-dependent, see Appendix C

Parameter Type:

Configurable

Refer also to parameters:

N/A

!

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.
