(1) Torque control

(a) Torque command and generated torque

A relationship between the applied voltage of the analog torque command (TC) and the torque
generated by the servo motor is shown below.
The maximum torque is generated at

8V. Note that the torque generated at

8V input can be

changed with parameter No. 26.

Forward rotation (CCW)

Reverse rotation (CW)

Generated torque limit values will vary about 5% relative to the voltage depending on products.
Generated torque may vary at the voltage of

−

0.05V to +0.05V.

The following table indicates the torque generation directions determined by the forward rotation
selection (RS1) and reverse rotation selection (RS2) when the analog torque command (TC) is used.
