Step 6. Connecting Encoder Feedback
The type of feedback the unit is capable of depends on the ICM (Interconnect module) chosen and additional
options ordered. Table 2.6 shows the different Encoder feedback types available for the DMC-40x0 including which
ICM and additional part numbers are required. Note that each feedback type has a different configuration
command. See the Command Reference for full details on how to properly configure each axis.
Different feedback types can be used on the same controller. For instance, one axis could be using Standard
quadrature and the next could be using SSI on the same ICM board. By default, all axis are configured for Standard
quadrature.

Although stepper systems do not require feedback, Galil supports a feedback sensor on each stepper axis. Servo motors require a
position sensor.
A note about using encoders and steppers:
When a stepper is used, the auxiliary encoder for the corresponding axis is unavailable for an external
connection. If an encoder is used for position feedback, connect the encoder to the main encoder input
corresponding to that axis. The commanded position of the stepper can be interrogated with
TD
and the
encoder position can be interrogated with
TP
.
The following steps provide a general guide for connecting encoders to the DMC unit:
Step A.
