groups
Stopping axes
groups
All axes in interpolated motion are decelerated to a stop.
Immediately
stopping axes
groups
All axes in interpolated motion are stopped immediately.
Setting axes
group override
factors
The blended target velocity is changed during interpolated motion.
Reading axes
group positions
Changing the
axes in a group
The command current positions and actual current positions of an axes group can be read.
The composition axes parameter in the axes group parameters can be overwritten temporarily.
The end point index of the cam table that is specified in the input parameter is changed.
Common items Cams
Setting cam
table properties
Saving cam
tables
The cam table that is specified with the input parameter is saved in non-volatile memory in the
CPU unit.
Generating cam The cam table that is specified with the input parameter is generated from the cam property
tables
and cam mode.
Parameters
Writing MC
settings
Some of the axis parameters or axes group parameters are overwritten temporarily.
Changing axis
parameters
You can access and change the axis parameters from the user program.
Auxiliary
functions
Count modes
Unit conversions
You can select either linear mode (finite length) or rotary mode (infinite length).
You can set the display unit for each axis according to the machine.
Acceleration/ Automatic
Jerk is set for the acceleration/deceleration curve for an axis motion or axes group motion.

Changing the
acceleration and
deceleration
rates
You can change the acceleration or deceleration rate even during acceleration or deceleration.
In-position check
You can set an in-position range and in-position check time to confirm when positioning is
completed.
Stop method
You can set the stop method to the immediate stop input signal or limit input signal.
Re-execution of motion control You can change the input variables for a motion control instruction during execution and
instructions execute the instruction again to change the target values during operation.
Multi-execution of motion con- You can specify when to start execution and how to connect the velocities between operations
trol instructions (buffer mode) when another motion control instruction is executed during operation.
Continuous axes group motions You can specify the transition mode for multi-execution of instructions for axes group operation.

Monitoring
functions
Software limits Software limits are set for each axis.
Following error The error between the command current value and the actual current value is monitored for an
axis.
Velocity, accel- You can set and monitor warning values for each axis and each axes group.

Absolute encoder support
You can use an OMRON 1S series servomotor or Accurax-G5 series servomotor with an ab-
solute encoder to eliminate the need to perform homing at startup.
Input signal logic inversion
You can inverse the logic of immediate stop input signal, positive limit input signal, negative
limit input signal or home proximity input signal.
External interface signals
The servo drive input signals listed below are used:
Home signal, home proximity signal, positive limit signal, negative limit signal, immediate stop
signal and interrupt input signal.
