MOTOR RATED ARM AMPS (P.008)

The rated armature current from the motor nameplate.

Parameter Range:

0 to 3000.0 Amps

Default Setting:

Depending on unit type

Parameter Type:

Configurable

OIM Menu Path(s):

Current Minor Loop (CML) - CML Feedback Scaling - Quick Start

CAUTION

The drive will not operate properly if this parameter value is entered incorrectly. This parameter must
be equal to the rated armature amps found on the motor nameplate. Overcurrent or excess heating of
the motor could result. Failure to observe this precaution could result in damage to, or destruction of,
the equipment.

This value is used by the internal I

t motor thermal overload function. This function allows for continuous

operation at 100% current and 60 seconds of operation at 150% of rated MOTOR RATED ARM AMPS
(P.008) following an inverse time overload curve.

MOTOR RATED ARM VOLTS (P.009)

Rated armature voltage from the motor nameplate.

Parameter Range:

160 to 675 VDC on types with nominal voltage up to 500 VAC

240 to 1000 VDC on types with nominal voltage 690 VAC (see 4.5.11)

Default Setting:

240

VDC

Parameter Type:

Configurable

OIM Menu Path(s):

Speed/Voltage Loop (SPD) - Speed/Volt Loop (SPD) Feedback -Quick Start

Refer also to Parameter:

NOMINAL AC LINE VOLTS (P.307)

WARNING

The incorrect setting of this parameter can cause an overspeed condition. This parameter must be set
by a qualified person who understands the significance of setting it. Set the value of this parameter
accurately per your application requirements. Failure to observe this precaution could result in bodily
injury.
