(2) Setting
1) Select the advanced magnetic flux vector control, real sensorless vector control or vector control.
2) Set "1" or "101" in Pr. 96 Auto tuning setting/status .
When the setting is "1" . . . . . . . . Tuning is performed without motor running.
·
· When the setting is "101" . . . . . . Tuning is performed with motor running.
3) Set the rated motor current (initial value is rated inverter current) in Pr. 9 Electronic thermal O/L relay.
4) Set the rated voltage of motor (initial value is 200V/400V) in Pr. 83 Rated motor voltage and rated frequency of motor
(initial value is 60Hz) in Pr. 84 Rated motor frequency .
(For a Japanese standard motor, etc. which has both 50Hz and 60Hz rated values, set 200V/60Hz or 400V/60Hz).)
For vector control dedicated motor SF-V5RU1 / V5RU3 / V5RU4, set as the following table.
SF-V5RU1-30kW or less
SF-V5RU1-37kW
SF-V5RU3-22kW or less
SF-V5RU3-30kW
SF-V5RU4-3.7kW, 7.5kW
SF-V5RU4-other than the above
REMARKS
·
When using the vector control dedicated motor SF-V5RU (1500r/min series) or SF-THY, setting 33 and 34 in Pr. 71 selects
internal constants appropriate for dedicated motors. Therefore, Pr. 83 and Pr. 84 settings are unnecessary.
·
Perform auto tuning for SF-V5RU (except for 1500 r/min series) with setting 13 or 14 in Pr. 71 ( For perform auto tuning, set
Pr. 83 and Pr. 84)
5) Set Pr. 71 Applied motor according to the motor used.
Mitsubishi standard motor
Mitsubishi high efficiency motor
Mitsubishi constant-torque motor
Vector control dediated motor

standard motor
Other manufacturer's

* For other settings of Pr. 71, refer to chapter 4 of
It takes approximately 25 to 120s
(Excitation noise is produced during tuning.)
*Tuning time differs according to the inverter capacity and motor type.
It takes approximately 40s until tuning is completed.
The motor runs at nearly its rated frequency.
