z 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. But a PLS2(887)
instruction can be executed while a ACC(888) instruction (continuous mode) is being executed.
It is possible to start another operation during acceleration/deceleration and start another positioning
instruction during positioning.
