Single-axis Synchronized Control

This section describes the operation of synchronized control for single axes.

Overview of Synchronized Control

Synchronous control synchronizes the position of a slave axis with the position of a master axis. The
command position or actual position of any axis can be specified for the master axis. If the command
velocity for the slave axis exceeds the maximum velocity that is set in the axis parameters, the com-
mand is performed at the maximum velocity of the axis. If this occurs, any insufficient travel distance is
distributed and output in the following periods.
Precautions for Correct Use Precautions for Correct Use
• You cannot specify an encoder axis or virtual encoder axis for the slave axis.

Gear Operation

This function specifies the gear ratio between the master axis and the slave axis and starts operation.
Start gear operation with the MC_GearIn (Start Gear Operation) instruction. End synchronization with
the MC_GearOut (End Gear Operation) instruction or the MC_Stop instruction.
Specify with
Master_Reference.

You can set the gear ratio numerator, gear ratio denominator, position type, acceleration rate, and
deceleration rate for the slave axis to operate. For the master axis, you can specify the command posi-
tion, actual position, or most recent command position.
After operation starts, the slave axis uses the velocity of the master axis times the gear ratio for its tar-
get velocity, and accelerates/decelerates accordingly. The catching phase exists until the target velocity
is reached. The InGear phase exists after that. If the gear ratio is positive, the slave axis and master
axis move in the same direction. If the gear ratio is negative, the slave axis and master axis move in the
opposite directions.
For details on gear operation, refer to the MC_GearIn (Start Gear Operation), MC_GearOut (End Gear
Operation), and MC_Stop instructions in the NY-series Motion Control Instructions Reference Manual
(Cat. No. W561).
