Selection and protection of a motor
(2) Setting
1) Select the Advanced magnetic flux vector control, Real sensorless vector control or vector control
(refer to page 92 )
.
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 (refer to page 183 )
.
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 page 187.

SF-V5RU1-37kW 170V
SF-V5RU3-22kW or lower 160V
SF-V5RU3-30kW 170V

REMARKS
· When using the vector control dedicated motor SF-V5RU (1500r/min series) and 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 value 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.
