To Exhibit The Best Performance Of The Motor Performance (Offline Auto Tuning) (Pr. 71, Pr. 80 To Pr. 84, Pr. 90 To Pr. 94, Pr. 96, Pr. 859) - Mitsubishi Electric FR-E700 Instruction Manual

Selection and protection of a motor
6.8.3 To exhibit the best performance of the motor performance
(offline auto tuning) (Pr. 71, Pr. 80 to Pr. 84, Pr. 90 to Pr. 94, Pr. 96, Pr. 859)
The motor performance can be maximized with offline auto tuning.
What is offline auto tuning?
● When performing advanced magnetic flux vector control or general-purpose magnetic flux vector
control, the motor can be run with the optimum operating characteristics by automatically
measuring the motor constants (offline autotuning) even when each motor constants differs,
other manufacturer's motor is used, or the wiring length is long.

Description
By selecting a standard motor or constant-
torque motor, thermal characteristic and
motor constants of each motor are set.
Applied motor capacity.
V/F control
Number of motor poles.
V/F control
Tuning data
(The value measured by offline auto tuning
is automatically set.)
Uses the Mitsubishi motor
(SF-JR, SF-HR, SF-JRCA, SF-HRCA) constants.
Rated motor voltage (V).
Rated motor frequency (Hz).
Tuning data
(The value measured by offline auto tuning
is automatically set.)
9999: Uses the Mitsubishi motor
(SF-JR, SF-HR, SF-JRCA, SF-HRCA) constants.
Offline auto tuning is not performed
For advanced magnetic flux vector control
Offline auto tuning is performed without
motor running (all motor constants).
For general-purpose magnetic flux vector
control
Offline auto tuning is performed without
motor running.
(motor constant (R1) only)
Offline auto tuning for V/F control
(automatic restart after instantaneous
power failure (with frequency search))
Tuning data
(The value measured by offline auto tuning
is automatically set.)
Uses the Mitsubishi motor
(SF-JR, SF-HR, SF-JRCA, SF-HRCA) constants.
