Available Inputs (continued)
CW Limit Switch or CCW Limit Switch
Each input can be defined as a CW or CCW Limit Switch. When used this way, the inputs are used to define
the limits of mechanical travel. For example, if you are moving in a clockwise direction and the CW Limit
Switch activates, all motion will immediately stop. At this point, you will only be able to move in the counter-
clockwise direction.
Start Indexer Move Input
Indexer Moves are programmed through the Network Data like every other move. The only difference is that
Indexer Moves are not run until a Start Indexer Move Input makes a inactive-to-active state transition. This
allows a Networked Driver to run critically timed moves that cannot be reliably started from the network due
to data transfer lags.
If Inputs 1 and 2 are programmed as quadrature encoder inputs and Input 3 is programmed as a Start Indexer
Move Input, then the quadrature encoder position data will be captured whenever Input 3 transitions. An inac-
tive-to-active state transition will also trigger an Indexer Move if one is pending.
Emergency Stop Input
When an input is defined as an Emergency Stop, or E-Stop Input, motion will immediately stop when this
input becomes active. The driver remains enabled and power is supplied to the motor. No move can begin
while this input is active.
Stop Jog or Registration Move Input
When an input is configured as a Stop Jog or Registration Move Input, triggering this input during a Jog
Move or Registration will bring the move to a controlled stop. The controlled stop is triggered on an inactive-
to-active state change on the input. Only Jog Moves and Registration Moves can be stopped with this input
type, all other moves will ignore this input.
If Inputs 1 and 2 are programmed as quadrature encoder inputs and Input 3 is programmed as a Stop Jog or
Registration Move Input, then the quadrature encoder position data will be captured when Input 3 makes an
inactive-to-active transition to bring a Jog or Registration Move to a controlled stop. The encoder position
data is not captured if a Jog or Registration Move is not in progress. If you want to capture encoder position
data on every transition of Input 3, configure it as a Start Indexer Move Input.
Capture Encoder Position Input
As described in the Start Indexer Move Input and Stop Jog or Registration Move Input sections above, a
Networked Driver can be configured to capture the encoder position value on a transition on Input 3.
Encoder Feedback
Each Networked Driver can be configured to accept a quadrature encoder instead of discrete inputs. 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.
Additional information on the ways to use an encoder with a Networked Driver is described in the Encoder
Functionality section on page 18.
