Motor Capacity (kW)

This user-input parameter identifies the wattage rating of the motor.

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — No

Minimum — 0.10

Maximum — (ASD-dependent)

Units — kW

Motor Constant #1

Program

Motor Settings

Motor Constant #1 (Primary resistance)

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.

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — No

Minimum — 0.0

Maximum — 100,000 M

Motor Constant #2

Program

Motor Settings

Motor Constant #2 (Secondary

Resistance)

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 (motor tuning) is required to use the Vector Control, Automatic
Torque Boost
, or Automatic Energy-saving functions.

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — No

Minimum — 0.00

Maximum — Open

Motor Constant #3

Program

Motor Settings

Motor Constant #3 (Exciting

Inductance)

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.

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — No

Minimum — 0.00

Maximum — 6500.0

Units — µH

Motor Constant #4

Program

Motor Settings

Motor Constant #4 (Load Inertia)

This parameter is used to compensate for the affects of 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.

Parameter Type — Numerical

Factory Default — 1.0

Changeable During Run — Yes
