Chapter 9 Major Positioning Control
Current feed value during 2-axis speed control
The following table shows the "[Md.20] Current feed value" during 2-axis speed
control corresponding to the "[Pr.21] Current feed value during speed control"
settings. (Note that the reference axis setting values are used for parameters.)
"[Pr.21] Current feed value during speed
control" setting
[Md.20] Current feed value
0: Do not update current feed value
The current feed value at speed control start
is maintained.
1: Update current feed value The current feed value is updated.
2: Zero clear current feed value The current feed value is fixed at 0.

Restrictions
(1) Set "Positioning complete" in "[Da.1] Operation pattern". The error
"Continuous path control not possible" (error code: 516) will occur and the
operation cannot start if "continuous positioning control" or "continuous path
control" is set. ("Continuous positioning control" and "continuous path
control" cannot be set in speed control.)
(2) Set the WITH mode in "[Pr.18] M code ON signal output timing" when using an
M code. The M code will not be output, and the M code ON signal will not turn
ON if the AFTER mode is set.
(3) Set the "reference axis speed" in "[Pr.20] Interpolation speed designation
method". The error "Interpolation mode error" (error code: 523) will occur and
the operation cannot start if a composite speed is set.
