Differences between Set Frequencies and Actual Frequencies
The following tables show when a second pulse control instruction can be started if a pulse control
operation is already being executed.
A second independent-mode positioning instruction can be started if an independent-mode positioning
instruction is being executed, 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 a PLS2 instruction can be executed while a ACC
instruction (continuous mode) is being executed.
It is possible to start another operation during acceleration/deceleration and start another positioning
instruction during positioning
:Can be executed. :Error occurs.
