CHAPTER 1
INTRODUCTION TO THE SD17060E
The SD17060E
The SD17060E is a 6.0Arms micro-stepping drive with a 170Vdc internal
bus voltage. What makes the SD17060E unique is its built-in indexer that
accepts configuration and command data from a host system over the
internal Ethernet port. This combination of host and drive gives you sev-
eral advantages:
h
Sophisticated I/O processing can be performed in the host (PLC or
other controller) before sending commands to the SD17060E
h
All motion logic is programmed in the host, eliminating the need to
learn a separate motion control language
h
Eliminating the separate indexer lowers Total System Cost
The first protocol released for the SD17060E is Ethernet/IP, which makes
the SD17060E easy to integrate into Allen-Bradley controller systems.
The SD17060E is powered by a nominal 120Vac 50/60Hz source. The
output motor current is fully programmable from 1.0Arms to 6.0Arms
which makes the SD17060E compatible with AMCI’s complete line of
size 23 through size 42 stepper motors. Steps per Turn, Idle Current
Reduction, Current Loop Gain, and Anti-Resonance Circuit are also fully
programmable. If you have used other stepper indexer products from
AMCI you will find programming to be very similar to these products.
In addition to power and motor hookups, the SD17060E has three DC inputs and one DC output that are used
by the indexer. Configuration data from the host sets the function of these points. The output can be config-
ured to be a Fault Output or a general purpose output. Each input can be individually configured as a:
h
CW Limit Switch
h
CCW Limit Switch
h
Home Limit Switch
h
Capture Position Input to optionally stops a manual jog
h
Emergency Stop Input
In addition to these functions, the inputs can be programmed to accept a quadrature encoder with marker
pulse. An encoder input gives you the ability to:
h
Home the machine to the encoder marker pulse
h
Make absolute and relative moves based on the encoder count instead of the stepper pulse count.
h
Detect motor stall conditions.
An encoder input also allows you to drive the motor through a feature called 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.
This manual is designed to get you up and running quickly using the SD17060E stepper drive.
As such, it assumes you have some basic knowledge of stepper systems, such as the resolution
you want run your motor at, and the reasons why you’d want to use Idle Current Reduction and
the reasons why you wouldn’t. If these terms or ideas are new to you, we’re here to help. AMCI
has a lot of information on our website and we are adding more all the time. If you can’t find what
