DRIVING THE MOTOR
(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.
It takes approximately 25 to 120s
* until tuning is completed.
(Excitation noise is produced during tuning.)
*Tuning time differs according to the inverter capacity and motor type.
· When the setting is "101" . . . . . . Tuning is performed with motor running.
It takes approximately 40s until tuning is completed.
The motor runs at nearly its rated frequency.
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.
5) Set Pr. 71 Applied motor according to the motor used.
* For other settings of Pr. 71, refer to Chapter 4 of the Instruction Manual (Applied).

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)
· When Pr. 11 DC injection brake operation time = "0" or Pr.12 DC injection brake operation voltage = "0," offline auto tuning is
performed at the initial setting of Pr. 11 or Pr. 12.
· When the positioning control is selected (Pr. 800 = "3" or "5" (when MC signal is OFF)), offline auto tuning is not performed.
