SELECTION
(2) Torque characteristic
SF-V5RU SF-THY
SF-V5RU1, 3, 4
*1 Maximum speed of SF-V5RU-55kW and SF-V5RU1-30kW is 2400 r/min.
*2 Maximum speed of a dedicated motor SF-V5RU-3.7kW or less is 3600 r/min. Consult our sales office when using the motor at
the maximum speed.
*3 Maximum speed of the motor with brake is 1800 r/min.
(3) Others
Refer to page 263 for the combination of an inverter
and a vector control dedicated motor.
Combination of a standard motor with encoder is also
available.
Connect the encoder directly to the backlash-free
motor shaft.
