Device Setup
The SETDEVICE program instruction allows the external encoders to be initialized and
various parameters to be set up. The action taken by the SETDEVICE instruction depends
upon the value of the command parameter.
The syntax of the SETDEVICE instruction is
SETDEVICE (0, unit, error, command) p1, p2
The following table describes the valid commands.
Command Description
0 Initialize Device
This command sets all scale factors, offsets, and limits to their default
values, as follows: offset = 0; scale factor = 1; no limit checking. This
command also resets any errors for the specified device.This
command should be issued before any other commands for a
particular unit and before using the DEVICE real-valued function for
the unit.
1 Reset Device
This command clears any errors associated with this encoder unit. It
does not affect the scale factor, offset, or limits.
8 Set Scale Factor
This command sets the position and velocity scale factor for this
encoder unit to the value of parameter p1. The units are millimeters
per encoder count. The scale factor must be set before setting the
offset or limits. If the scale factor is changed, the offset and limit
values will need to be updated.
9 Set Position Offset
This command sets the position offset for this encoder unit to the
value of parameter p1. The units are millimeters. The scale factor
must be set before setting the offset.
10 Set Position Limits
This command sets the position limits for the encoder unit to the
values of optional parameters p1 and p2, which are the lower and
upper limits, respectively. If a parameter is omitted, no checking is
performed for that limit. The units are millimeters. The scale factor
must be set before setting the limits.
