(Note): Example of the above Motion SFC program is started using the automatic start or sequence program.
(a) The current value to change uses the following devices.
• Indirect setting....... Data register (D)
Link register (W)
Motion register (#)
Multiple CPU area device (U \G)
• Direct setting ......... Decimal constant (K)
(b) Precautions
• When the synchronous encoder current value is changed in the real mode,
an error occurs and the current value change is not executed.
(Note-1)
• The synchronous encoder current value change can be executed even
during operation in the virtual mode operation (during pulse input from the
synchronous encoder).
(Note-1)
When the current value is changed, the synchronous encoder current
value will be continued from the changed value.
• Even if a synchronous encoder current value is changed, it will have no
effect on the output module current value.
(Note-1): The current value change can be executed in real mode for the
version (Refer to Section 1.4) that supports "synchronous encoder
current value monitor in real mode".
