Pulse Outputs Section 5-2
Combinations of
Pulse Control
Instructions
The following tables show when a second pulse control instruction can be
started if a pulse control operation is already being executed.
Generally, a second independent-mode positioning instruction can be started
if an independent-mode positioning instruction is being execute, and a second
continuous-mode speed control instruction can be started if a continuous-
mode speed control instruction is being executed. Operation cannot be
switched between the independent and continuous modes, although
PLS2(887) can be started while ACC(888) (continuous mode) is being exe-
cuted.
It is possible to start another operation during acceleration/deceleration and
start another positioning instruction during positioning.
