Coordinate 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).
Parameter name
Coordinate parameters are used to set the offset for each axis from the
machine origin or the reference origin.
Parameter name
Reference origin offset value
Workpiece origin offset value
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.
Function
Specifies the minimum unit for the machine system
settings: 1, 0.1, 0.01, 0.001. 0.0001.
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.
Specifies whether the motor will rotate in forward or reverse
when the command voltage to the servomotor driver is
positive (+).
Specifies the stopping method used when an emergency
stop or limit input is received.
Sets the type of encoder used.
Sets the number of encoder pulses output (encoder fre-
quency dividing ratio) when the servomotor rotates once.
Sets the encoder ratio: 1, 2 or 4
Sets whether the encoder will advance in phase A or phase
B when the servomotor is rotating in the forward direction.
Sets how much the axis will move per feedback pulse
(numerator/denominator, set individually).
Sets the number of servomotor rotations with a speed
reference of 10 V applied.
Sets the limit monitored in the software.
Sets the origin search operation mode.
Sets whether to move in the positive or negative direction
when performing an origin search.
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.
Sets whether the origin proximity input is normally open or
normally closed.
Decide to whether or not to perform wiring check at the time
of servo lock.
Sets the time from test pulse output until the feedback
pulse is checked.
Sets the number of test pulses in the wiring check.
The ABS encoder default setting is displayed when it is exe-
cuted.
Origin position in the reference
coordinate system (offset from the
machine origin)
Origin position in the workpiece
coordinate system (offset from the
reference origin)
