CONNECTING YOUR CONTROLLER

I/O Connector

The I/O connector on the SD17060B accepts inputs from your indexer

as well as the Disable Input and Fault Output.

All SD17060B-03 drivers and SD17060B drivers sold after Decem-

ber, 2008, have inputs that accept 5Vdc differential signals and can

also be wired to accept single ended sinking or sourcing inputs of up

to 24Vdc without the need of an additional current limiting resistor.

SD17060B-25 units only have 24Vdc inputs. See

on page 3 for information on determining when your unit was shipped

from the AMCI factory.

Input Wiring

All inputs on the SD17060B are low

voltage, low power signals. All wiring

should use shielded, twisted pair cable

such as Belden 9727 instrumentation

cable.

The shield of the cable should be

grounded at one end only, preferably at

the indexer or controller. Do not ground

the shields at the SD17060B. If you

must splice the cable, do not connect the

shields to ground of the junction box.

Indexer Inputs

These inputs can be programmed to

accept Step & Direction or CW/CCW

pulses. This setting is controlled by

SW1-1.

Disable Input

When active, the motor current is off

and the driver does not accept indexer

pulses. The active state of the Disable

Input is set by switch SB1-4.

An additional load resistor may be

required on some PLC outputs to

improve switching time. A symptom of

this problem is that the motor will begin

to run rough at high speeds. A 470 or

560 ohm resistor should be used. For

5V and 12V systems use a 1W resistor.

For 24V systems use a 2W resistor.

These power ratings assume that the out-

put can be normally on. For systems

where you are sure the output is always

normally off, the wattage ratings can be

cut in half.
