When turning on power, since EXOFA is not valid until transmission between CNC
and Spindle Amplifier connected, mask EXOF to ‘1’ by the timer.

At the condition of Guard State signal (SGD) is ‘0’ (guard open) and Spindle
enabling switch (SPEN) is ‘0’ (drive disable), check that the spindle excitation
signal (EXOF) is ‘1’ . If the inconsistency is detected while a certain time(*1), invoke
