Default Settings, Saved Parameters, Conﬁguration Flags,

Limits and Positions

The controller keeps track of several sets of ﬂags, parameters and other saved conﬁguration

variables. It is important to understand how changing some of these parameters aﬀect the other sets.

The parameter sets are discussed below, starting with the most permanent settings and continuing to

the least permanent settings.

Motor Driver Alignment Parameters

The motor driver alignment parameters are set with the AA and AZ commands. These commands set

nonvolatile digital potentiometers located in the driver circuitry. These settings are independent of

the other parameters settings and are immediately saved on the digital pots themselves.

Conﬁguration Flags

The conﬁguration ﬂags are set with the

and #6 (the DIP switches change between linear and rotary mode for the XY stage and Z-axis drive

respectively). The conﬁguration ﬂags allow the loaded ﬁrmware to work with a variety of speciﬁc

hardware conﬁgurations. Speciﬁc lead screw pitch, linear encoder resolution, encoder type, and piezo

Z-axis range are some examples of the conﬁgurations settings that can be changed. (See the CCA

command for details). The conﬁguration ﬂags are usually only changed when the controller is ﬁrst set

up for a particular set of hardware, when new ﬁrmware is loaded using the ASI Updater, or when

changing between linear and rotary encoder for the stage. When a conﬁguration ﬂag is changed, it is

immediately saved in nonvolatile memory; the controller must be restarted for the new conﬁguration

to be implemented.

Saved Parameters

There are many operating parameters that can be changed in the controller. These include such

things as error tolerances (E and PC commands), speed and acceleration times (S and AC commands),

servo parameters settings (KP, KI, and KD commands), and many others. All of these operating

parameters have Factory Default settings that have been determined to be appropriate for most

typical situations. A user may ﬁnd that a change to some parameter value will improve the

performance of the system for their application. When parameter values are changed using a serial

command, the new parameter immediately becomes active in the controller. Third party software

vendors can change parameter settings "on the ﬂy" using their software and the changes will remain

active as long as the controller remains powered on and not RESET. Parameter changes can be made

Whenever any conﬁguration ﬂag is changed, the controller

restores any Saved Parameter settings back to the Factory
