Parameter Selection and protection of a motor
FR-E700 SC EC/ENE 6 - 91
The setting range and increments of Pr. 82, Pr. 90 to Pr. 94 and Pr. 859 changes according to the setting
value of Pr. 71 and Pr. 96.
햲
When Pr. 71 = "0, 1, 40 or 50", or setting value of Pr. 96 read after performing offline auto tuning is
not "3, 13, 23".
햳
When Pr. 71 = "5, 6, 15, or 16"
햴
When Pr. 71 = "3, 13, 23, 43 or 53" and setting value of Pr. 96 read after performing offline auto
tuning is "3, 13, 23". Or when Pr. 71 = "4, 14, 24, 44 or 54".
●
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 select-
ed.
●
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 standard
motor (SF-JR 0.2 kW or more), high efficiency motor (SF-HR 0.2 kW or more) and Mitsubishi
constant-torque motor (SF-JRCA four-pole, SF-HRCA 0.2 kW to 15 kW) are used or the wiring
length is long (30 m or more), 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.
●
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).
●
Do not connect a surge voltage suppression filter (FFR-DT) between the inverter and motor.

CAUTION:
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 performance is unaffected even if the motor runs slightly.
