Effect of intervention to coordinate system
– The manual handle pulses are
also added to the offset
on the appropriate axis in
the common work zero
point offset registers.
This way all the works
and local coordinate sys-
tems are being shifted.
– Naturally this does not influ-
ence the machine coordi-
nate system. In case of
G53 or G28 the axis al-
ways moves to the ap-
propriate position.
– The value rotated by manual
handle cannot be seen on
the display showing the current position in compliance with the above discussed.
If one of the common work zero point offsets is other than zero an exclamation mark ! can be
seen in the 7th status field.
