8.4 Torque characteristics
POINT
For the machine where the unbalanced torque occurs, such as a vertical axis
system (lift), use the absolute position detection system. (Refer to section 2.1
(4).) The unbalanced torque should be kept at 70% or less of the rated torque.
When the power supply input of the servo amplifier is 3-phase 200 V AC or 1-phase 230 V AC, the torque
characteristic is indicated by the heavy line. For the 1-phase 100 V AC power supply, part of the torque
characteristic is indicated by the broken line.

Mounting precautions
If the mounting surface has low rigidity, machine resonance may occur. Securely mount the direct drive
motor on the mounting surface having high rigidity.
To ensure sufficient rigidity, fully tighten the mounting screws for the direct drive motor and rotary table.
To ensure the accuracy and heat dissipation of the direct drive motor, closely mount the motor on the
mounting surface having a sufficient heat dissipation area and high rigidity. Do not leave a gap between
the mounting surface and the bottom of the direct drive motor.
The mounting accuracy of the flange type is higher than that of the table type. If the direct drive motor
needs to be mounted with high accuracy, select the flange type.
For the machine accuracies of each direct drive motor, refer to section 2.8. For the dimension tolerance,
refer to section 8.6.
