•
Byte 1 contains the Connector Code, a hex number.
•
Bytes 2-3 contain the Signal Code, a decimal number.
•
Bytes 4-5 are not used and should contain 0.

Signal Codes
Note in the following Signal Code table that only some of the signals have a default output.
Signal Code Signal Description
Default Output to:
00 decimal* %AQ
Force Analog Output
data* Connector C or D
10 decimal Servo Axis 1 Torque Command None
15 decimal Servo Axis 1 Actual Velocity Connector A
20 decimal Servo Axis 2 Torque Command None
25 decimal Servo Axis 2 Actual Velocity Connector B
* Cannot be re-routed. This signal code can only be used to restore this signal back to its default output.
Note
The analog output is not available for user control on digitally controlled axes.
Issuing the Force Analog Output or the Select Analog Output commands for
digital axes will have no effect on these analog outputs.
The
Select Analog Output Mode
has three basic uses:
(1) Re-route either
Servo Axis 1 Actual Velocity
or
Servo Axis 2 Actual Velocity
from its default
output to a different output. The %AQ
Force Analog Output
data signal cannot be re-routed
to a different connector; however, it can be replaced on its default output connector (C or D)
by another signal that is routed there by the
Select Analog Output Mode
command.
(2) Route one of the two signals lacking a default output,
Servo Axis 1 Torque Command
and
Servo Axis 2 Torque Command,
to one of the outputs, thus replacing the previous signal on
that output. This is shown in Example 2, below.
(3) Restore signals with default outputs that were replaced by a re-routed signal. In Example 2,
the
%AQ Force Analog Output
signal, which is normally found on Connector D by default, is
replaced by the
Servo Axis 1 Torque Command
signal that was routed to connector D by the
Select Analog Output Mode
command. In Example 3, the
%AQ Force Analog Output
signal
is restored to Connector D by using the
Select Analog Output Mode
command.
