Synchronous encoder current value changing instructions
• The current value change of the synchronous encoder is executed if
operation is being performed in the virtual mode (during pulse input from
the synchronous encoder).
If the current value is changed, the feed current value of the synchronous
encoder continues from the new value.
• The current value change of the synchronous encoder does not affect the
current value of the output module.
• Set the current value change program of the synchronous encoder shaft
program within the virtual mode program No. range set in "K mode allocation"
of MT Developer2.
• When PLC ready flag (M2000) or PCPU READY complete flag (SM500) is OFF,
a minor error (Note-2)
• If a synchronous encoder current value change is executed in the real
mode, a servo program setting error
value change is not made. ([903] when the current value change servo program
is set to within the virtual mode program No. range, or 905 when it is set to
within the real mode program No. range.)
• If a current value change is made during mode changing, a servo program
setting error (Note-2)
mode real mode changing) occurs and the current value change is not made.
(Note-1)
(Note-1): The current value change can be executed in real mode for the version
(Refer to Section 1.3) that supports "incremental synchronous encoder
current value in real mode".
(Note-2): Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22)
Programming Manual (REAL MODE)"/"Q173D(S)CPU/
Q172D(S)CPU Motion controller (SV22) Programming Manual (VIRTUAL
MODE)" for minor error, major error and servo program setting error.
