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.
Accelera-
tion/decel-
eration
control
Automatic accelera-
tion/deceleration control
The acceleration/deceleration curve is automatically
adjusted for an axis motion or axes group motion. You can
select a trapezoidal curve or you can set the jerk for an S-
curve.
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 determine when the immedi-
ate stop input signal or limit input signal is valid.
Re-execution of motion control instruc-
tions
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 connect
the velocities between operations when another motion con-
trol instruction is executed during operation.
Continuous axes group motions (Tran-
sition Mode)
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.
You can detect when a range is exceeded during axis motion
and when the target position is outside the range when a
motion control instruction is executed. You can also set
warning values.
Following error
The following error between the command current value and
the actual current value is monitored for each axis and an
error is created to stop motion if a set value is exceeded.
Velocity, acceleration
rate, deceleration rate,
torque, interpolation
velocity, interpolation
acceleration rate, and
interpolation decelera-
tion rate
You can set warning values for each axis and each axes
group.
Absolute encoder support
You can use an OMRON G5-series Servomotor with an
Absolute Encoder to eliminate the need to perform homing at
startup.
Backlash compensation
Servo Drive auxiliary functions are used.
The compensation method and setting range depend on the
specifications of the Servo Drive.
External interface signals
The following Servo Drive input signals are used.
Home signal, home proximity signal, positive limit signal,
negative limit signal, immediate stop signal, and interrupt
input signal
