To Exhibit The Best Performance Of The Motor Performance (Offline Auto Tuning) (Pr. 9, Pr. 71, Pr. 83, Pr. 84, Pr. 96) - Mitsubishi Electric FR-E700 Instruction Manual

Basic settings
5.1.8 To exhibit the best performance of the motor performance
(offline auto tuning) (Pr. 9, Pr. 71, Pr. 83, Pr. 84, Pr. 96)
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 vec-
tor control, the motor can be run with the optimum operating characteristics by automatically
measuring the motor constants (offline auto tuning) even when each motor constants differs,
other manufacturer's motor is used, or the wiring length is long.

NOTES This function is made valid only when a value other than "9999" is set in Pr. 80 and Pr. 81
and advanced magnetic flux vector control or general-purpose magnetic flux vector control is
selected.)
You can copy the offline auto tuning data (motor constants) to another inverter with the PU
(FR-PU07).
Even when motors (other manufacturer's motor, SF-JRC, etc.) other than Mitsubishi stand-
ard motor, high efficiency motor (SF-JR, SF-HR 0.2kW or more), and Mitsubishi constant-
torque motor (SF-JRCA four-pole, SF-HRCA 0.4kW to 15kW) are used or the wiring length
is long, using the offline auto tuning function runs the motor with the optimum operating
characteristics.
Tuning is enabled even when a load is connected to the motor. As the motor may run slightly,
fix the motor securely with a mechanical brake or make sure that there will be no problem in
safety if the motor runs (caution is required especially in elevator). Note that tuning perform-
ance is unaffected even if the motor runs slightly.
Reading/writing/copy of motor constants tuned by offline auto tuning are enabled.
The offline auto tuning status can be monitored with the operation panel and PU (FR-PU04/
FR-PU07).

Description
Set the rated motor current.
By selecting a standard motor or constant-torque motor,
thermal characteristic and motor constants of each
motor are set.
Set the rated motor voltage (V).
Set the rated motor frequency (Hz).
Offline auto tuning is not performed
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)) (refer to section 6.12.1)
