Common
items
Cams
*5
Setting cam table proper-
ties
The end point index of the cam table that is specified in
the input parameter is changed.
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 tables (*) The cam table that is specified with the input parameter is
generated from the cam property and cam node.
Parameters Writing MC settings Some of the axis parameters or axes group parameters
are overwritten temporarily.
Changing axis parame-
ters (*)
You can access and change the axis parameters from the
user program.
Auxiliary
functions
Count modes You can select either Linear Mode (finite length) or Rotary
Mode (infinite length).
Unit conversions You can set the display unit for each axis according to the
machine.
Acceleration/decel-
eration control
Automatic accelera-
tion/deceleration control
Jerk is set for the acceleration/deceleration curve for an
axis motion or axes group motion.
Changing the accelera-
tion 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 instructions You can change the input variables for a motion control
instruction during execution and execute the instruction
again to change the target values during operation.
Multi-execution of motion control instructions
(Buffer Mode)
You can specify when to start execution and how to con-
nect the velocities between operations when another
motion control instruction is executed during operation.
Continuous axes group motions (Transition
Mode)
You can specify the Transition Mode for multi-execution of
instructions for axes group operation.
Monitoring func-
tions
Software limits The movement range of an axis is monitored.
Following error The error between the command current value and the
actual current value is monitored for an axis.
Velocity, acceleration
rate, deceleration rate,
torque, interpolation
velocity, interpolation
acceleration rate, and
interpolation decelera-
tion rate
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 G5-
series Servomotor with an Absolute 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 on the right are used.
Home signal, home proximity signal, positive limit signal,
negative limit signal, immediate stop signal, and interrupt
input signal
