Section 6-2
6.
ACC(888) (Ind.) to PLS2(887)
• The number of output pulses can be changed (even during acceleration
or deceleration.)
• The frequency can be changed (even during acceleration or decelera-
tion.)
• The acceleration/deceleration rate can be changed (even during acceler-
ation or deceleration.)
• The output mode and direction cannot be switched.
7.
ACC(888) (Cont.) to PLS2(887)
• The frequency can be changed (even during acceleration or decelera-
tion.)
• The acceleration/deceleration rate can be changed (even during acceler-
ation or deceleration.)
• The output mode and direction cannot be switched.
8.
PLS2(887) to PLS2(887)
• The number of output pulses can be changed (even during acceleration
or deceleration.)
• The frequency can be changed (even during acceleration or decelera-
tion.)
• The acceleration/deceleration rate can be changed (even during acceler-
ation or deceleration.)
• The output mode and direction cannot be switched.
Relative Pulse Outputs and Absolute Pulse Outputs
Selecting Relative or
Absolute Coordinates
The pulse output PV's coordinate system (absolute or relative) is selected
automatically, as follows:
• When the origin is undetermined, the system operates in relative coordi-
nates.
• When the origin has been determined, the system operates in absolute
coordinates.
Conditions
Origin has been
determined by an ori-
gin search
Origin has been
determined by exe-
cuting INI(880) to
change the PV
Origin not estab-
lished (Origin search
has not been per-
formed and PV has
not been changed
with INI(880).)
