Relationship between the
Coordinate System and
Pulse Specification
The following table shows the pulse output operation for the four possible
combinations of the coordinate systems (absolute or relative) and the pulse
specifications (absolute or relative) made when PULS(886) or PLS2(887) is
executed.

Origin not established:
The Pulse Output 0 Origin Established Flag
(A28005) or Pulse Output 1 Origin Established
Flag (A28105) will be ON.
Origin established:
The Pulse Output 0 Origin Established Flag
(A28005) or Pulse Output 1 No-origin Flag
(A28105) will be OFF.
Relative pulse speci-
fication
Positions the system to another position relative to the current position.
Number of movement pulses = number of pulses setting
The pulse output PV after instruction execution =
Number of movement pulses = Number of pulses
setting
Note The pulse output PV is reset to 0 just before pulses
are output. After that, the specified number of
pulses is output.
The following example shows the number of
pulses setting = 100 counterclockwise.
Pulse output PV range:
80000000 to 7FFFFFFF hex
Number of pulses setting range:
00000000 to 7FFFFFFF hex
The pulse output PV after instruction execution =
PV + Number of movement pulses.
The following example shows the number of
pulses setting = 100 countercloskwise.
Pulse output PV range:
80000000 to 7FFFFFFF hex
Number of pulses setting range:
00000000 to 7FFFFFFF hex
