MD 5600-5629 0010 0000
For rotary axes (NC MD 564*, bits 5-1)! Acts on linear axes as well.
The actual-value display jumps from 359.999 to 0 degrees after one
revolution of the rotary axis.
Rotary axes, see also Section Functional Descriptions.
Active On: RESET
The NC can detect precisely the direction in which the reference point
lies from the "Deceleration" interface signal, as the reference point
extends up to the traversing limit (also see Section Axis (Analog) and
Spindle Installation).
Active On: NC STOP
Ref. point
If the axis is between the reference point cam and EMERGENCY STOP
when the control is powered up, the axis moves to EMERGENCY STOP
during reference point approach, as the control cannot detect from the
"Deceleration" interface signal whether the axis is ahead of or behind
the reference point cam (also see Section Axis (Analog) and Spindle
Installation).
The software limit switches defined in NC MD 224* to 236* are overrun
without a reaction of any kind. The working field limitation (setting data)
is not in force.
