158 P9 ASD Installation and Operation Manual
Motor Rated RPM
Program Motor Vector Motor Model
This parameter is used to input the (nameplated) rated speed of the motor.
Direct Access Number — F407
Parameter Type — Numerical
Factory Default — 1730
Changeable During Run — No
Minimum — 100
Maximum — 60000
Units — RPM
Base Frequency Voltage 1
Program Vector Vector Motor Model
The Motor 1 Base Frequency Voltage 1 is the Motor 1 output voltage at the
Base Frequency (
F014). Regardless of the programmed value, the output
voltage cannot be higher than the input voltage.
The actual output voltage will be influenced by the input voltage of the ASD
and the Supply Voltage Correction setting (
F307).
Direct Access Number — F409
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 50.0
Maximum — 660.0
Units — Volts
Motor Constant 1 (Torque Boost)
Program Motor  Vector Motor Model
This parameter sets the primary resistance of the motor. Increasing this value
can prevent a drop in the torque of the motor at low speeds. Increasing this
value excessively can result in nuisance overload tripping.
Direct Access Number — F410
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 0.0
Maximum — 30.0
Units — %
Motor Constant 2 (No-Load Current)
Program Motor Vector Motor Model
This parameter is used to set the current level required to excite the motor.
Specifying a value that is too high for this parameter may result in hunting
(erratic motor operation).
Direct Access Number — F411
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 10
Maximum — 90
Units — %
Motor Constant 3 (Leak Inductance)
Program Motor Vector Motor Model
This parameter is used to set the leakage inductance of the motor.
A larger setting here results in higher output torque at high speeds.
Direct Access Number — F412
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 0
Maximum — 200
Units — %
Motor Constant 4 (Rated Slip)
Program Motor Vector Motor Model
This parameter is used to set the secondary resistance of the motor.
An increase in this parameter setting results in an increase of compensation for
motor slip.
Direct Access Number — F413
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 0.01
Minimum — 25.00
Units — %
