Using the conventional motor and
other motors
(3) Parameter setting
Parameters below are extended parameters. Set "1" in Pr. 160 "extended function selection" to read and make setting.
1.12.2 Precautions for and wiring of the motor with encoder (SF-JR with encoder)
• When the motor used is other than the dedicated motor, use the offline auto tuning function. (Refer to page 120
for details of offline auto tuning.)
• Set Pr. 800 to select the control method. (Refer to page 169.)
• To protect the motor from overheat, set electronic thermal relay function or provide an external thermal relay.
(Refer to page 27.)

CAUTION
• Pr. 71 setting
· SF-VR: "30"
· SF-JR (2, 4, 6P)- 2.2 to 55kW: "0"
SF-JR (4P)- 1.5kW or less: "20"

• When using motors other than the dedicated motor (SF-V5RU) or above motors, perform offline auto
tuning. (Refer to page 120.)
Motor with encoder
CAUTION
• *Leave the unused terminals open.
• When not using an external thermal relay, set "0" in Pr. 876 "thermal relay protector input". Set Pr. 9
"electronic thermal O/L relay".
• Check the power supply specification of encoder and change a jumper connector. (Refer to the
Instruction Manual (basic).)
