Motor Constant 1 (primary resistance)
Program ⇒ Motor Parameters ⇒ Vector Motor Model
This parameter is the measurement of the stator resistance and is considered a
Motor Constant (unchanging). This value is used in conjunction with other
constants to tune the motor.
To use Vector Control, Automatic Torque Boost, or Automatic Energy-
saving, the Motor Constant setting (motor tuning) is required.
Direct Access Number — F402
Parameter Type — Numerical
Factory Default — (drive dependent)
Changeable During Run — No
Minimum — 0.0
Maximum — 100,000 MΩ
Units — Ω
Motor Constant 2 (secondary resistance)
Program ⇒ Motor Parameters ⇒ Vector Motor Model
This parameter is the measurement of the rotor resistance and is considered a
Motor Constant (unchanging). This value is used in conjunction with other
constants to tune the motor.
This setting is used to maximize the effectiveness of the Vector Control,
Automatic Torque Boost, or Automatic Energy-saving functions.
Direct Access Number — F403
Parameter Type — Numerical
Factory Default — (drive dependent)
Changeable During Run — No
Minimum — 0.00
Maximum — Open
Units — Ω
Motor Constant 3 (exciting inductance)
Program ⇒ Motor Parameters ⇒ Vector Motor Model
This parameter is used to input the excitation inductance for the motor. This
value is used in conjunction with other constants to tune the motor.
This setting (motor tuning) is required to use the Vector Control, Automatic
Torque Boost, or Automatic Energy-saving functions.
Direct Access Number — F404
Parameter Type — Numerical
Factory Default — (drive dependent)
Changeable During Run — No
Minimum — 0.00
Maximum — 6500.0
Units — µH
Motor Constant 4 (load inertia)
Program ⇒ Motor Parameters ⇒ Vector Motor Model
This parameter is used to control the load inertia during speed changes.
Acceleration and deceleration overshoot may be reduced by increasing this
value.
This setting (motor tuning) is required to use the Vector Control, Automatic
Torque Boost, or Automatic Energy-saving functions.
Direct Access Number — F405
Parameter Type — Numerical
Factory Default — 1.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 100.0
Motor Constant 5 (leakage inductance)
Program ⇒ Motor Parameters ⇒ Vector Motor Model
This parameter provides slight increases in the output voltage of the drive at the
high speed range.
This setting (motor tuning) is required to use the Vector Control, Automatic
Torque Boost, or Automatic Energy-saving functions.
Direct Access Number — F410
Parameter Type — Numerical
Factory Default — (drive dependent)
Changeable During Run — No
Minimum — 0.00
Maximum — 650.0
