Parameters U511 User’s Manual
4-86 Aerotech, Inc. Version 1.1
4.11.3. “Keep position after reset?” (y/n)
This parameter configures the UNIDEX 511 to either clear (that is, set to 0) all absolute,
relative and machine positions following a reset (no) or to retain the current axis values
(yes).
Axis positions are often programmed to a known location following a home cycle. A
home cycle is often commanded as a normal startup function, in which case the setting of
this parameter is immaterial. It is suggested, however, that this parameter be set to yes, as
it may aid in recovering information and diagnosing problems.
This parameter can have one of two possible settings that are listed in Table 4-63.
Table 4-63. Settings for Parameter 001
Value Function
Yes Maintains position information following a reset
No
Clears position information following a reset (default)
This parameter defaults to “no.” This means that the position counter will clear the
position information following a reset.
If the axis moves during the reset more than 16,384 counts for an encoder or 1/2
revolution for a resolver, the UNIDEX 511's position tracking registers (and the axis
position display of the Program mode software window) will not be accurate after the
reset.
