System Parameters Section 3-3
Machine Parameters Machine parameters determine the minimum unit setting, rotation direction,
stop method, and other machine configuration settings, as well as the operat-
ing procedure and type of servomotor used. The parameters are set for each
axis that is used (X, Y, Z and U axes).
Coordinate Parameters Coordinate parameters are used to set the offset for each axis from the
machine origin or the reference origin.
The machine origin is the origin set at origin search and is where the encoder
counter reads zero. It is set from the absolute origin setting when an absolute
encoder is used.
Parameter name Function
Minimum unit setting Specifies the minimum unit for the machine system
settings: 1, 0.1, 0.01, 0.001. 0.0001.
Axis Mode/display unit Specifies Normal Feed Mode or Unlimited Feed Mode at
Axis Mode and specifies the unit that will be used when
monitoring the present position: mm, inches, degrees,
pulses.
Rotation direction Specifies whether the motor will rotate in forward or reverse
when the command voltage to the servomotor driver is
positive (+).
Emergency/limit input stopping methods Specifies the stopping method used when an emergency
stop or limit input is received.
Encoder ABS/INC Sets the type of encoder used.
Encoder resolution Sets the number of encoder pulses output (encoder fre-
quency dividing ratio) when the servomotor rotates once.
Encoder ratio Sets the encoder ratio: 1, 2 or 4
Encoder polarity Sets whether the encoder will advance in phase A or phase
B when the servomotor is rotating in the forward direction.
Pulse rate Sets how much the axis will move per feedback pulse
(numerator/denominator, set individually).
Max. motor frequency Sets the number of servomotor rotations with a speed
reference of 10 V applied.
Positive (+) or negative (–) software limit Sets the limit monitored in the software.
Origin search method Sets the origin search operation mode.
Origin search direction Sets whether to move in the positive or negative direction
when performing an origin search.
Origin deceleration method Sets whether to use the origin proximity input signal or to
use the limit input signal as the origin proximity input signal
and it sets the deceleration method used when a limit input
signal is detected.
Origin proximity input logic Sets whether the origin proximity input is normally open or
normally closed.
Wiring check Decide to whether or not to perform wiring check at the time
of servo lock.
Wiring check time Sets the time from test pulse output until the feedback
pulse is checked.
Wiring check pulses Sets the number of test pulses in the wiring check.
ABS encoder default setting The ABS encoder default setting is displayed when it is exe-
cuted.
Parameter name Function
Reference origin offset value Origin position in the reference
coordinate system (offset from the
machine origin)
Workpiece origin offset value Origin position in the workpiece
coordinate system (offset from the
reference origin)
