If adjustment of the parameter values previously described has resulted in unstable
or unsatisfactory system response, the ‘Defaults’ tab can be used to reset all
parameter values to the factory default settings.
To restore the default values:
1) Select the ‘Defaults’ tab.
2) Click the ‘Reset Parameter Defaults in the Controller’ check box,
3) Click OK.
4) The controller must then be power cycled before the default values can take
effect.

Changing the parameters under the "Advanced" tabs can cause the motor to become
unstable or uncontrollable. If these settings are persisted, the unit may not be able to
phase initialise the axis correctly the next time it powers up and, as a result, APT will
not display some or any of the panels. If this occurs, the unit can be set to a special
mode where the persisted settings are ignored and the default (safe) operating
parameters are loaded after power-up.
To enter this mode, power down the unit and set the rear panel ‘CH1 ID’ switch to 'D'.
When the unit is powered up, it will load the default set of operating parameters for all
channels. In this mode parameters can still be persisted but they will not be loaded on
start-up as long as the "CH1 ID" switch is set to 'D'. Moving the CH1 ID switch back
to its original position will re-enable the operating parameters that were last persisted.
