closes the position loop. It is usually not advisable to insert any acceleration or deceleration
control in these applications. The lagging response created by acc/dec limits can cause some
strange response performance.
To setup the S200 Position node for Step and Direction:
Drive Setup\Drive Setup; Mode of Operation: Electronic Gearing
Drive Setup \ Gearing; Gearing Type: Pulse / Direction
Drive Setup \ Gearing; Electronic Gearing Command Ratio: As desired
Profile Setup; Homing: Auto home, or as desired.
Accel / Decel: As desired but should be set to maximum
I/O Setup \ Digital Inputs: Gearing Active w/ (w/o) Correction
Other settings: As desired
The following descriptions for Indexer, Positioner, and Registration index
are provided here in description text because of the decidedly different
needs in the application. In realty, the S200 Position Node combines all
three of these features into the same group of Motion Tasks and does not
differentiate these as Operation Modes – all three control types can be
NOTE
combined into a single motion task list.

The term 'Indexer' is synonymous with 'Feeder' in the motion control industry. These applications
are incremental. A typical application is a 'cut to length' machine that feeds material into a shear
to be cut off over and over again. Each move concerns itself only with the position at which the
feed (index) begins. It has no concern about any other position information.
The S200 PN provides extremely flexible options in indexing applications. Up to 180 index moves
can be defined in the 'Motion Tasking Table'. The S200 Motion Tasking table can combine
indexing and positioning and can offer 'registration indexing' or 'automatic' moves and dwells.
Data for the move can be modified over the CAN bus or the Modbus interface allowing flexibility
for the overall machine design.
To setup the S200 Position node for Indexing:
Drive Setup\Drive Setup; Mode of Operation: Motion Tasks
Profile Setup; Homing: Auto home, or as desired.
Accel / Decel: Affects homing and jog rates only
I/O Setup \ Digital Inputs: Assign as required which may include BCD select, start move,
and in-position output.
Profile Setup \ Motion List; Up to 180 defined moves.
Other settings: As desired
