3. Signals
Safe speed selection signal A
SPA1~SPA4 <G338#0~#3> <DI+006#0~#3> (for spindle axes)
Safe speed selection signal B
SPB1~SPB4 <G338#4~#7> <DI+006#4~#7> (for spindle axes)
[Classification] Input signal
[Function] These signals select safe speed in dual check safety function.
These signals are provided for each axis; the affixed number of the signal name
shows the axis number.
SPA1, SPB1
1: Safe speed selection for the 1st spindle axis
2: Safe speed selection for the 2nd spindle axis
3: Safe speed selection for the 3rd spindle axis
4: Safe speed selection for the 4th spindle axis
[Operation] The relation between the safe speed signals and safe speed is as follows:
