Pulse Outputs
Section 5-3
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
output (absolute or relative) specified when PULS(886) or PLS2(887) is exe-
cuted.

Origin not established:
The No-origin Flag will be ON in this case.
Origin established:
The No-origin Flag will be OFF in this case.
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 num-
ber 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 counterclockwise.
Pulse output PV range:
80000000 to 7FFFFFFF hex
Number of pulses setting range:
00000000 to 7FFFFFFF hex
