Feed current value during 2-axis speed control
The following table shows the "[Md.20] Feed current value" during 2-axis speed
control corresponding to the "[Pr.21] Feed current value during speed control"
settings. (Note that the reference axis setting values are used for parameters.)

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.
