PROGRAMMABLE PARAMETERS

The 1222 controller has a number of parameters that can be programmed us-
ing a Curtis 1313 handheld programmer or 1314 Programming Station. The
programmable parameters allow the steering performance to be customized to
fit the needs of specific applications.

PARAMETER MENU CHARTS

The programmable parameters are grouped into nested hierarchical menus, as
shown in Table 3. The menu charts contain descriptions of each parameter.

PARAMETER ATTRIBUTES

Some parameters are subject to one or both of the following conditions, as
noted in the menu charts.

Parameter Change Fault (PCF)

When a new value is written, a Parameter Change Fault (code 49) is issued.
This is true both for writes via a CAN message and for writes via the serial bus
(using the 1313/1314 programmer). For safety purposes, the Parameter Change
Fault forces the vehicle operator to cycle power; cycling power clears the fault.
Subject parameters are marked • .
Requires Idle State (RIS)
To successfully write the parameter, a Device State = 0 (Not Ready to Switch
On), 2 (Switch On Disabled), 3 (Ready to Switch On) or 14 (Fault) is required.
This is true both for writes via a CAN message and for writes via the serial bus
(using the 1313/1314 programmer). The 1222 will reply with an Abort message
to any write attempted when the Device State is not one of those listed above.
The 1222 will not process the aborted write message, which means the new
parameter value will not be written. Subject parameters are marked
