General-Purpose Magnetic Flux Vector Control Selection (Pr. 80) - Mitsubishi FR-E540-0.4K-EC Instruction Manual

4.2.34 General-purpose magnetic flux vector control selection (Pr. 80)

Pr. 80 "motor capacity"
You can set the general-purpose magnetic flux
vector control.
" General-purpose magnetic flux vector control
Provides large starting torque and sufficient low-speed torque.
If the motor constants vary slightly, stable, large low-speed torque is provided
without specific motor constant setting or tuning.

If any of the following conditions are not satisfied, faults such as torque shortage and
speed fluctuation may occur. In this case, select V/F control.
<Operating conditions>
! The motor capacity is equal to or one rank lower than the inverter capacity.
! The number of motor poles is any of 2, 4, and 6. (4 poles only for the constant-
torque motor)
! Single-motor operation (one motor for one inverter) is performed.
! The wiring length between the inverter and motor is within 30m. (If the length is over
30m, perform offline auto tuning with the cables wired.)
<Setting>
(1) General-purpose magnetic flux vector control
! The general-purpose magnetic flux vector control can be selected by setting the
capacity of the motor used in Pr. 80.
