When the constant velocity section of the master axis is negative, a constant velocity travel distance
error occurs and the axis stops.
If you want to feed the slave axis at the same velocity as the master axis, set the following value as
the travel distance of the slave axis.

Precautions for Correct Use
If the counter mode for the master axis is Rotary Mode, specify a value that is within one ring
counter cycle for MasterDistance (Master Axis T
ravel Distance).
LinkOption (Synchronization Start Condition)
Specify the condition for the slave axis to synchronize with the master axis.
•
Start of Instruction
When this instruction is executed, the slave axis performs positioning in synchronization with the
master axis from the next period.
• When Trigger Is Detected
When the input signal specified as the input trigger occurs, the slave axis synchronizes with the
master axis and performs positioning from the next period.
• When the Master Axis Reaches the Master Following Distance
When the master axis reaches the master following distance during instruction execution, the slave
axis starts synchronization and performs positioning from the next period.
Even if the instruction is executed while the master axis is stopped at the master following distance,
the slave axis starts synchronization and performs positioning from the next period.
