Available Inputs (continued)
General Purpose Input
If your application does not require all three inputs, you can configure the unused inputs as General Purpose
Inputs. The inputs are not used by the Networked Driver, but the input state is reported in the network data.
Encoder Functionality
Inputs 1 and 2 can be programmed to accept the ±A and ±B signals from a quadrature encoder. When using an
encoder, you have two additional choices when configuring Input 3. First, the ±Z signal can be wired to Input
3 and used to home the machine. Second, Input 3 can be used to capture the encoder position when it transi-
tions if it is programmed as a Capture Encoder Position Input or a Jog Move Stop Input.
Using an encoder input gives you the ability to:

Home the machine to the encoder marker pulse

Detect motor stall conditions

Run Encoder Registration Moves
Electronic Gearing
In this mode, the stepper motor follows the rotation of an external encoder. This encoder is typically attached
to another motor. The ratio of encoder pulses to stepper pulses is programmable over a wide range. This mode
electronically couples the two motors together through a programmable gear ratio.
Encoder Registration Move
The encoder position acts as a registration mark in an Encoder Registration Move. Typically, the encoder is
mounted separately from the motor. With this mode, the Networked Driver will drive the motor until the
desired encoder count is reached, at which time the motor begins to decelerate and stop. This functionality is
useful in spool winding or unwinding applications, where the motor drives the spool and the encoder mea-
sures the material length as it enters or exits the spool. As the spool diameter increases or decreases, the pro-
grammed distance remains the same because you are measuring material, not the number of turns.
