Target
A rotary axis (machine axis 4 [AX4]) is to be moved to Fixed Point 2 (90 degrees) with the "Approaching fixed point in JOG"
function.
The machine data for the "Approaching fixed point" function of machine axis 4 are parameterized as follows:
MD30610 NUM_FIX_POINT_POS[AX4] = 4
4 fixed points are defined for machine axis 4.
MD30600 FIX_POINT_POS[0,AX4] = 0
1st Fixed point of AX4 = 0 degree
MD30600 FIX_POINT_POS[1,AX4] = 90
2nd Fixed point of AX4 = 90 degree
MD30600 FIX_POINT_POS[2,AX4] = 180
3rd Fixed point of AX4 = 180 degree
MD30600 FIX_POINT_POS[3,AX4] =
270
4th Fixed point of AX4 = 270 degree
Machine axis 4 is referred and is in Position 0 degree. This corresponds to the 1st fixed point and is output via the following
NC/PLC interface signal:
DB390x.DBX1001.0 = 1 (bit 0 - 2 = 1)
Approaching fixed point 2
The control system is switched in"JOG" mode.
The "Approaching fixed point" procedure for fixed point 2 is activated via the following NC/PLC interface signal:
DB380x.DBX1002.1 = 1 (bit 0 - 2 = 2)
Activation is confirmed by the following NC/PLC interface signal:
DB390x.DBX1001.1 = 1 (bit 0 - 2 = 2)
The Plus traverse key in the machine control table is used to traverse continuously to approach Fixed Point 2.
The machine axis 4 stops at the 90 degree position. This is signaled via the following NC/PLC interface signal:
DB390x.DBX1001.4 = 1 (bit 3 - 5 = 2)
AXCONF_MACHAX_NAME_TAB[n]
Machine axis name [n = axis index]
Defines movement in the opposite direction
HANDWH_IMP_PER_LATCH[0]...[2]
Handwheel pulses per locking position
Handwheel path or velocity specification
Channel-specific
Geometry axis in channel [n = geometry axis index]
Geometry axes with transverse axis functions
Fixed-point positions for the axis
Number of fixed-point positions for an axis
Rapid traverse in "JOG" mode
