2.22.9 Example

Connection of incremental valuator
1. TRACK A on X1.0
2. TRACK B on X1.1
3. TRACK N on X1.2
Connection of limit switch (active 0 V, open-circuit potential 24 V)
1. Limit switch END+ on X1.3 (reached when counting up)
2. Limit switch END- on X1.4 (reached when counting down)
Connection of drive
1. DIR+ on X1.5 (direction for axis when counting up)
2. DIR- on X1.6 (direction for axis when counting down)
3. SPEED on X1.7 (0 V: slow; 24 V: fast)
Switch on
Reference movement, variant 1 on limit switch END+
1. Loading of setting for operating mode 0A00 0000 0000 0000 0400 (PLC-
>module, word 1 – 5, hexadecimal format)
2. Axis moves slowly in direction END+ (DIR+=24 V, DIR-=0 V, SPEED=0 V)
3. When END+ is reached (END+=0 V), the traversing direction changes (DIR+=0
V, DIR-=24 V, SPEED=0 V)
4. After exiting the limit switch in a decremental traversing direction, the axis
stops at the first zero impulse (DIR+= 0 V, DIR-=0 V, SPEED=0 V). The counter
is deleted and the conclusion of the reference movement is signalled:
0000 0000 0000 0000 0019 (module->PLC, word 1 – 5, hexadecimal format)
OFF
1. Loading of setting for operating mode 0000 0000 0000 0000 0400 (PLC-
>module, word 1- 5, hexadecimal format)
Positioning movement, variant 1
1. Loading of pre-disconnection value (0000 0800) 0000 0800 0000 0000 0100
(PLC->module, word 1 – 5, hexadecimal format)
2. Loading of disconnection value (0000 1000) 0000 1000 0000 0000 0200 (PLC-
>module, word 1 – 5, hexadecimal format)
3. Loading of setting for operating mode 0100 0000 0000 0000 0400 (PLC-
>module, word 1 – 5, hexadecimal format)
4. Axis moves quickly in incremental direction (DRIVE+=24 V, DRIVE-=0 V,
SPEED=24 V)
5. Once the pre-disconnection value is reached, axis moves slowly in incremental
direction (DRIVE+=24 V, DRIVE-=0 V, SPEED=0 V)
6. The axis stops when the disconnection value is reached (DIR+=0 V, DIR-=0 V,
SPEED=0 V) and the conclusion of the positioning movement is signalled:
0000 1000 0000 0000 001A (PLC->module, word 1 – 5, hexadecimal format)
