Torque Characteristic - Mitsubishi Electric MELSERVO-J3 Series Instruction Manual

2. DIRECT DRIVE MOTOR

2.5.3 Torque characteristic

When the power supply input of the servo amplifier are 3-phase 200VAC or 1-phase 230VAC, the torque
characteristic is indicated by the heavy line. For the 1-phase 200VAC power supply, part of the torque
characteristic is indicated by the thin line. The 1-phase power supply input is applicable to the TM-RFM002C20,
TM-RFM004C20, TM-RFM006C20, TM-RFM006E20, TM-RFM012E20, TM-RFM012G20 and TM-RFM040J10.

POINT
When using a machine which generates unbalanced torque including a vertical
axis, use an absolute position detection system (Rrefer to section 2.3.1 (4)). It is
recommended that the unbalanced torque is 70% or less of the rated torque.
