Delta DVP-20PM - Page 93

3 Devices
 When bit 3 in D1846 (D1926, D2006) is ON, counterclockwise pulses are generated at the JOG
speed set.
5. Bit 4 in D1846 (D1926, D2006): A mode of variable motion is activated.
 After bit 4 in D1846 (D1926, D2006) is set to 1, the DVP-20PM series motion controller will
execute variable motion, and it will send pulses by a pulse generator.
 After a mode of variable motion is activated, the V
BIAS
of the axis specified will increase to its V (I).
When the axis operates, users can change its V (I) at will. The DVP-20PM series motion controller
accelerates or decelerates according to the V (I) set.
 Users can stop variable motion by setting bit 0 in D1846 (D1926, D2006,) to 1, or by setting bit 4 in
D1846 (D1926, D2006) to 0.

6. Bit 5 in D1846 (D1926, D2006): A manual pulse generator is operated.
 If bit 5 in D1846 (D1926, D2006) is set to ON, a manual pulse generator mode will be activated.
Please refer to the descriptions of D1858~D1864 (D1938~D1944, D2018~D2024) for more
information.
7. Bit 6 in D1846 (D1926, D2006): A mode of triggering the return to home is activated.
 When bit 6 in D1846 (D1926, D20066) is turned from OFF to ON, a mode of triggering the return
to home is activated. The mode of triggering the return to home varies with the present command
position of the axis specified. There are two situations.

Limit switch
Position (1): Position [1] is at the right side of the home and DOG, and DOG is OFF.
Position (2): Position [2] is at the right side of the home, and DOG is ON.
Position (3)*: Position [3] is at the left side of the home and DOG. DOG is OFF, and LSN is OFF.
Position (4)*: Position [4] is at the left side of the home and DOG. DOG is OFF, and LSN is ON.
*: A DVP-10PM series motion controller does not have LSN and LSP, and therefore does not
support position (3) and position (4).
8. Bit 7 in D1926: Triggering single-speed motion by means of an external signal
 If bit 7 in D1926 is set to ON, single-speed motion can be triggered by an external signal. After
DOG1’s signal goes from low to high or from high to low, the single-speed motion will be executed.
If PG1 is turned ON when the Y-axis moves to the range which is not masked, the motion of the
Y-axis will stop immediately, and CLR1 will be ON twenty microseconds after PG1’s signal goes
from low to high or from high to low. The speed of the single-speed motion depend on the V (I)
