9-5-1  3310 hex: Torque Compensation
9-5 Torque Output Setting Objects
These objects are used for the torque output setting.
Sets the torque compensation.
 
• Adjusts the amount of viscous friction compensation torque.
• Sets the amount of torque at 10,000 r/min.
• Sets the amount of unbalanced load torque compensation.
• Sets the amount of dynamic friction compensation in the positive direction.
