Sets the mechanical system which is connected to the motor.
• Sets the ratio of load inertia to the motor rotor inertia.
• Inertia ratio = (Load inertia ÷ Rotor inertia) × 100%
• Selects whether to enable or disable backlash compensation in the position control, and the opera-
tion direction for the compensation.
 Description of Set Values
• Sets the backlash compensation amount in the position control.
