Rated motor torque
For IM the torque value is calculated from the rated speed
(LF.11) and rated power (LF.10). Therefore this value is read
only.
Unit: lb ft
Value range: 1...10000 lb ft
Default setting: Calculated
For PM motors the torque value must be entered and is used
to establish the torque constant. Enter the rated name plate
torque.
Unit: lb ft
Value range: 1...10000 lb ft
Default setting: 18 lb ft
Adjustment value: enter the motor name plate value
Some motors have the torque stated in Nm. To convert Nm to
lb ft: multiply Nm by 0.738.
If the torque is not listed on the name plate you may use the the
following equations to calculate the torque:
Torque [lb ft] =
Name plate HP x 5258
Nameplate Speed (rpm)
OR
Torque [lb ft] =
Name plate kW x 7043
Nameplate Speed (rpm)
OR
Torque [lb ft] =
Name plate Nm
1.355
For PM machines changing LF.17 automatically sets the
maximum torque in 0.LF.36 to prevent high current to the
motor during construction.
For high speed operation, 0.LF.36 will typically need to be
raised to 200-250% of LF.17.
