Behavior of the continuous operation to torque control mode
If a workpiece comes into contact with a target object in the continuous operation to torque control mode, the torque control is
performed assuming that the command torque is the sum of the values set in [Target torque (Obj. 6071h)], [Pr. PE47
Unbalanced torque offset], and [Torque offset (Obj. 60B2h)]. If a workpiece does not come into contact with a target object, the
mode attempts to move the servo motor using the speed limit value set in [Velocity limit value (Obj. 2D20h)]. The command
torque and speed limit value can be changed in the continuous operation to torque control mode.
■
Current value in the continuous operation to torque control mode
[Position actual internal value (Obj. 6063h)] and [Position actual value (Obj. 6064h)] are continuously updated even in the
continuous operation to torque control mode. However, since the software position limit is disabled, [AL. 098 Software position
limit warning] will not occur even if [Position actual value (Obj. 6064h)] exceeds the software position limit value.

Switching between csp and continuous operation to torque control mode
The following shows a timing chart when the mode is switched between the csp mode and continuous operation to torque
control mode.
