When posting Motoman programs with ACC/DEC, PL needs to be set to -1 in program events (or manually be removed). The robot does not support both on the same line, suggest setting this info into the robot specifics or a popup during setting the ACC/DEC.
I do not remember if it is supported with using ACC with PL or DEC with PL. I will check this but all three is NOT supported by the robot. RoboDK does not differentiate this when setting ACC. It outputs both ACC and DEC with the same number as you set acceleration in 'set speed'. This also should be fixed so you can set BOTH ACC and DEC differently.
