Precautions for Correct Use Precautions for Correct Use
Do not execute the MC_SetPosition instruction for the Master (Master Axis) if you use this
instruction on a CPU Unit with unit version 1.09 or earlier.
If the MC_SetPosition instruction is executed for the Master (Master Axis), the Slave (Slave Axis)
may follow the Master (Master Axis) quickly.
If you want to use the MC_SetPosition instruction for the Master (Master Axis), disable the rela-
tionship between the Master (Master Axis) and Slave (Slave Axis) before executing the instruc-
tion.
• The MC Function Module calculates the velocity profile for linear acceleration and deceleration
with the following three velocities using the Acceleration (Acceleration Rate) and Deceleration
(Deceleration Rate).
• The velocity of the Slave (Slave Axis) when an instruction is executed is the initial velocity.
• The velocity of the Master (Master Axis) when an instruction is executed multiplied by the
gear ratio is the final velocity.
• The Velocity (Target Velocity) is the target velocity.
If the travel distance during the catching phase is too short, the target velocity will not be reached.
