CONNECTING YOUR CONTROLLER
I/O Connector
The I/O connector on the SD17040C accepts inputs from your indexer
as well as the Disable Input and Fault Output.
All inputs 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.
Input Wiring
All inputs on the SD17040C 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 SD17040C. If you
must splice the cable, do not connect the
shields to the 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
SB1-1.
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.
R
LD
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.
