p Specifying encoder reference marks
Encoder reference marks can be used to home the system when it is
started. The ND 2100G can be configured to prompt the user to cross
reference marks or to perform a hard stop machine zero prior to
measurements.
To specify encoder reference marks:
U Highlight the Ref Marks field
U Press the LIST soft key to display a list of reference mark types
U Highlight the desired reference mark type
U Press the ENTER key to select the reference mark type
U Press the ENTER key to advance to the next parameter
When Manual is selected, the operator will be prompted when
powering the system to move to the desired zero point and press the
ENTER key. When Ref, Abs AC, or Abs HH is selected, the operator
will be prompted to move the encoder to cross a reference mark.
The Reference Marks setup parameter has no meaning
when an RS-232 device is specified as the channel input.
If a reference has been specified, a password is required
to skip the reference initialization when power is applied to
the system.
