122 Q9 ASD Installation and Operation Manual
Base Frequency Voltage 1
Program

Motor Settings
The Base Frequency Voltage 1 is the ASD output voltage level 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 Voltage Compensation setting (
F307 ).
Direct Access Number — F409
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 50.0
Maximum — 660.0
Units — Volts
Motor Constant 1 (Torque Boost)
Program

Motor Settings
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 Settings
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 Settings
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 — Yes
Minimum — 0
Maximum — 200
Units — %
Motor Constant 4 (Rated Slip)
Program

Motor Settings
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 — Yes
Minimum — 0.01
Minimum — 25.00
Units — %
Exciting Strengthening Coefficient
No Path — Direct Access Only
This parameter is used to increase the magnetic flux of the motor at low-speeds.
This feature is useful when increased torque at low speeds is required.
Direct Access Number — F415
Parameter Type — Numerical
Factory Default — 100
Changeable During Run — Yes
Minimum — 100
Maximum — 130
Units — %
