4-5-3 Torque Control (Torque)
H Functions
• Controls the Servomotor output torque using analog voltage input from the torque command (TREF:
CN1-9, 10).
• You can change the relationship between the torque command and output torque using the torque
control scale (Pn400) setting.

Details
Note Servomotor operation with torque control varies according to the Servomotor load conditions
(e.g., friction, external power, inertia). Perform safety measures on the devices to prevent Servo-
motor runaway.
