Set a safety speed for each axis.
The CNC and monitor always check the velocity command of each
axis in the dual check safety function. If the safety speed is exceeded
on one axis at least, the guard unlock signal (*LGD) is brought to 0, to
disable guard unlocking. The state in which the safety speed is not
exceeded on any axis is one condition for setting the guard unlock
signal (*LGD) to 1 (to enable guard unlocking).
If the safety speed is exceeded in safety signal mode C (state in which
a guard open request is input and the guard is open), a servo alarm
No.476 or No.494 is issued for the corresponding axis.
Up to four safety speeds can be set. Which safety speeds to choose
depends on the safety speed/safety position selection signal (safety
input signal). For details, see Section 5.2, "SIGNALS."
Safety speed 1 assumes the value of parameter No. 1942 if parameter
No. 1942 is not set to 0. Safety speed 1 assumes the value of
parameter No. 13821 if parameter No. 1942 is set to 0.

By setting bit 1 (TR2x) of parameter No. 13802 to 1, a safety speed
can be monitored not by mm/min, inch/min, and deg/min but by motor
speed (min
