Indexer Functionality
The table below lists the functionality offered by the indexer built into the SMD17K.
Table R1.1 Indexer Functionality
Feature Description
Synchronous
Moves
Using the Distributed Clock functionality of the EtherCAT system, multiple devices
can synchronize the start of their moves to the SYNC0 signal. Moves will begin
within ±25 microseconds of each other.
Programmable
Inputs
Each of the inputs can be programmed as a Home Limit, Over Travel Limit, Capture
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 SMD17K homes to a discrete
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.
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 location.
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 programmable
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 located in the output registers. 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 position
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 SMD17K is purchased with an encoder option, the encoder can be used to
verify motion when a move command is issued.
