Definition
task_compliance_ctrl(stx, time)
Features
This function begins task compliance control based on the preset reference coordinate system.
Caution
-
In non-FTS models (A0509, A0912, A0509F, A0912F, E0509), compliance control is only possible in the translation direction, and the control error may be large.
-
If the command is used in a simulation environment without a robot, it may not operate normally.
-
In the Non-FTS modeIf the command is used in a simulation environment without a robot, it may not operate normally.l, when using a robot near a singularity, it may not operate normally.
-
Compliance/force control may be affected by singularities, which can cause vibrations. Please be cautious and avoid using it near singularities.

Example
P0 = posj(0,0,90,0,90,0)
movej(P0)
task_compliance_ctrl() # Begins with the default stiffness
set_stiffnessx([500, 500, 500, 100, 100, 100], time=0.5)
# Switches to the user-defined stiffness for 0.5 sec.
release_compliance_ctrl()
task_compliance_ctrl([500, 500, 500, 100, 100, 100])
# Begins with the user-defined stiffness.
