7000-TD002A-EN-P – September 2007
Magnetizing Inductance Regen [Lm Regen]
Linear Number: 693
Default Value: 1.00
Minimum Value: 0.50
Maximum Value: 2.00
Access Level: Service
Read/Write: Read/Write
This parameter represents the ratio between the Magnetizing Inductance of the motor when running at
full regeneration to the Rated Magnetizing Inductance. Since a motor is a non-linear device, Magnetizing
Inductance is the parameter that changes the most with load and flux levels, and for applications with
Tachometer enabled and Low Speed, High Torque operating conditions, this parameter may need to be
used to extrapolate Magnetizing Inductance for any load and flux reference. For most standard
applications, the default value of 1.00 is acceptable.
Magnetizing Inductance No Load Flux Min [Lm Noload FlxMin]
Linear Number: 694
Default Value: 1.00
Minimum Value: 0.50
Maximum Value: 2.00
Access Level: Service
Read/Write: Read/Write
This parameter represents the ratio between the Magnetizing Inductance of the motor at no load and
minimum flux command to the Rated Magnetizing Inductance. Since a motor is a non-linear device,
Magnetizing Inductance is the parameter that changes the most with load and flux levels, and for
applications with Tachometer enabled and Low Speed, High Torque operating conditions, this parameter
may need to be used to extrapolate Magnetizing Inductance for any load and flux reference. For most
standard applications, the default value of 1.00 is acceptable.
Magnetizing Inductance No Load Flux Max [Lm Noload FlxMax]
Linear Number: 695
Default Value: 1.00
Minimum Value: 0.50
Maximum Value: 2.00
Access Level: Service
Read/Write: Read/Write
This parameter represents the ratio between the Magnetizing Inductance of the motor at no Load and
maximum flux to the Rated Magnetizing Inductance. Since a motor is a non-linear device, Magnetizing
Inductance is the parameter that changes the most with load and flux levels, and for applications with
Tachometer enabled and Low Speed, High Torque operating conditions, this parameter may need to be
used to extrapolate Magnetizing Inductance for any load and flux reference. For most standard
applications, the default value of 1.00 is acceptable.
