Application example

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.
Parameter setting
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
MD30600 FIX_POINT_POS[1,AX4] = 90
MD30600 FIX_POINT_POS[2,AX4] = 180
MD30600 FIX_POINT_POS[3,AX4] = 270
Initial situation
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:
V390x 1001.0 = 1 (bit 0 - 2 = 1)
Approaching fixed point 2
The control is switched in the JOG mode.
The "Approaching fixed point" procedure for fixed point 2 is activated via the following
NC/PLC interface signal:
V380x 1002.1 = 1 (bit 0 - 2 = 2)
Activation is confirmed by the following NC/PLC interface signal:
V390x 1001.1 = 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:
V390x 1001.4 = 1 (bit 3 - 5 = 2)
