Positions can be set to within the range of 40-bit signed integers when they are converted to pulses.
The following functions are supported when connected to an OMRON G5-series Servo Drive with built-
in EtherCAT communications.
Cams
Cam data points
65,535 points max. per cam table
1,048,560 points max. total for all cam tables
Number of cam tables
640 tables max.
Cam profile curves
Created with Cam Editor.
Positions (master axis phase and slave axis displacement) can be
specified to change phase pitches for each section.
Overwriting cam data
Cam data can be overwritten from the user program.

Description
Single
axes
Single-axis
position
control
Absolute positioning
The absolute target position is specified to perform position-
ing.
Relative positioning
The travel distance from the command current position is
specified to perform positioning.
Interrupt feeding
Positioning is performed for the specified travel distance from
the position where an external device triggers an interrupt
input.
Single-axis
velocity
control
Velocity control
Velocity control is implemented in Position Control Mode.
Cyclic synchronous
velocity control
A velocity command is output each control period in Velocity
Control Mode.
Single-axis
torque con-
trol
Torque control
The torque of the motor is controlled.
Single-axis
synchro-
nized con-
trol
Starting cam operation
Cam operation is started using a specified cam table.
Ending cam operation
Cam operation is ended for the axis specified with the input
parameter.
Starting gear operation
The gear ratio between the master axis and the slave axis is
specified and gear operation is started.
Positioning gear opera-
tion
The gear ratio between the master axis and the slave axis
and the position to synchronize are specified and gear oper-
ation is started.
Ending gear operation
The current gear operation or positioning gear operation is
stopped.
Synchronous position-
ing
Positioning is performed in sync with the specified master
axis.
Master axis phase shift
The phase of the master axis currently in synchronized con-
trol is shifted.
Combining axes
The sum or difference of the command positions of two axes
is output as the command position.
Single-axis
manual
operation
Powering the Servo
The Servo for the Servo Drive is turned ON to enable opera-
tion.
Jogging
Jogging is performed according to the specified target veloc-
ity.
