Indexer Functionality
The table below lists the functionality offered by the indexer built into the SMD17E2.
Table R1.1 Indexer Functionality
Feature Description
EtherNet/IP,
PROFINET,
Modbus TCP
Allows easy setup and communication with a wide range of host controllers such
as the latest PLC’s from Allen-Bradley.
EtherNet/IP-DLR
SMD17E2 units have Device Level Ring functionality, which adds redundancy to
the EtherNet/IP protocol.
PROFINET-MRP
SMD17E2 units have Media Redundancy Protocol support, which adds redun-
dancy to the PROFINET protocol.
Programmable
Inputs
Each of the inputs can be programmed as a Home Limit, Over Travel Limit, Cap-
ture Input, Manual Jog Stop, Start Indexer Move, E-Stop, or a General Purpose
Input.
Programmable
Parameters
Starting Speed, Running Speed, Acceleration, Deceleration, and Accel/Decel
Types are fully programmable.
Homing
Allows you to set the machine to a known position. An SMD17E2 homes to a dis-
crete input and can use a bit in the Network Data as a home proximity input.
Jog Move Allows you to drive the motor in either direction as long as the command is active.
Synchrostep Move
Allows you to treat the SMD17E2 as a motion axis by constantly updating posi-
tion and velocity data to the unit.
Relative Move
Allows you to drive the motor a specific number of steps in either direction from
the current location.
Absolute Move
Allows you to drive the motor from one known location to another known loca-
tion.
Registration Move
Allows you to jog the motor in either direction based on an input bit from your
host controller. When a controlled stop is issued, the move will output a program
-
mable number of steps before coming to a stop.
Blend Move
Allows you to perform a sequence of relative moves without stopping between
them.
Dwell Move
Allows you to perform a sequence of relative moves with a stop between each
move that has a programmable length of time. Used to create highly accurate
move profiles that avoid network latency issues.
Indexer Move
Allows you to program a move that is held in memory. The move is run when one
of the programmable inputs makes a transition. Note that an Indexer Move
requires a connection to a host controller to program the move.
Hold Move
Allows you to suspend a move, and optionally restart it, without losing your posi-
tion value.
Resume Move Allows you to restart a previously held move operation.
Immediate Stop
Allows you to immediately stop all motion if an error condition is detected by
your host controller.
Stall Detection
When an SMD17E2 is purchased with an encoder option, the encoder can be used
to verify motion when a move command is issued.
