(4) Program
[Example]
To zero the system, the X and Y axis zeroing inputs are pulsed. In the event
of an error occurring during zeroing, the error number
is read to data
registers D l 1 and D l 2.
[Notes]
(1 Start conditions are shown in Table 6.7.
(2)
Interpolation is not enabled during zeroing.
Giving a simultaneous zeroing command to both axes causes one axis to
delay about 50ms before starting.
(3)
The system may only be zeroed once. Repeating the zeroing command
with no intermediate operation will give an error.
