4  APPLICABLE FUNCTIONS
4.13  Command offset

4.13

Command offset

"Command offset" is a function that compensates the position/speed/torque commands by adding a desired amount of offset 
to the commands. Position offset, velocity offset, and torque offset can be set.

 • The type of "command offset" that can be used differs depending on the control mode.

Page 113 Applicable control modes

Precautions

 • If the offset value difference between position/velocity/torque offsets is too large, the servo motor may rotate due to the 

sudden change in torque when the control mode is switched. Check the setting value of "command offset" when switching 
modes.

 • If the offset value difference between position/velocity/torque offsets is too large, the servo motor may rotate due to the 

sudden change in torque at servo-on. Check the setting value of "command offset" when switching modes.

 • Set "command offset" to "0" while the servo is off, and reset the value after the servo is turned on.
 • [Torque offset (Obj. 60B2h)] can be used simultaneously with [Pr. PE47 Unbalanced torque offset]. If a value other than "0" 

is set for both the parameter and the object, the setting values of both [Torque offset (Obj. 60B2h)] and [Pr. PE47 
Unbalanced torque offset] are added to the torque command.

 • If using the velocity offset in the position mode, a position deviation may occur at the command stop and positioning may 

not be completed as a result.

 • When using super trace control, do not use the velocity offset. To adjust the speed feed forward during super trace control, 

use [Pr. PB04 Feed forward gain].

Function

Outline

Position offset

• In the position mode, an offset can be added to [Target position (Obj. 607Ah)].

Velocity offset

• In the velocity mode, an offset can be added to [Target velocity (Obj. 60FFh)].
• In the position mode, an offset (speed feed forward) can be added to the speed command calculated internally to drive 

the servo motor.

Torque offset

• In the torque mode, an offset can be added to [Target torque (Obj. 6071h)].
• In the position mode and velocity mode, an offset (torque feed forward) can be added to the torque command calculated 

internally to drive the servo motor.
