HEIDENHAIN ND 1200T - Manual (Page 67)

Tool-Chek ® TC200
3-15
MZ Cnts
Allows the user to define the machine zero position of an en-
coder by moving it to the desired position.
Entering a zero in this field causes the TC200 to automatically
record the current position of the encoder as the machine zero at
the next startup. Subsequent startups will not change the ma-
chine zero unless this field is reset to zero first. This data entry
field requires the supervisor password prior to access.
Reversed
The normal convention for the display of the polarity of measure-
ments is:
• Motion to the right is positive (X axis)
• Motion up is positive (Z axis)
The settings for any axis can be reversed to accommodate the
encoder mounting requirements of the system used. Press the No
softkey to retain the positive polarity for the selected axis, or press
the Yes softkey to achieve the correct polarity for different en-
coder mounting. Press the down cursor arrow or Enter key to
advance the display and highlight Interpolation. This option se-
lection field requires the supervisor password prior to access.
