Using the XMP controller to power encoders?
Then
make sure that voltage drops in your cabling are NOT a problem.
If voltage drops are a problem, power the encoders using an external
supply. For every 100 mA of current drawn, the 5V_OUT voltage
may drop 0.2 volts or more (due to cable resistance). For example,
if two encoders each draw 150 mA, then 5V_OUT may drop to 4.4
volt at the encoders. This could cause your encoder to fail!
SERCOS
Drives
SERCOS
is a standardized industrial format utilizing fiber-optic technology.
The optical power demands of drives vary widely, depending upon
the drive itself, length of cables, etc. For more information
regarding SERCOS motion drive power demands, please see your drive's
manufacturer.
XMP-analog Controllers
XMP-analog
systems rely upon traditional copper wiring to pass analog signals
between the drive and controller. Two voltages are available for
opto-inputs on XMP controllers: 5VDC and 24VDC. To determine whether
your controller supports 5V or 24V, look for a sticker on the
XMP circuit board. The sticker will say either "5V" or "24V."
Detailed
information regarding configuration of analog I/O is provided
in Chapter 4. Specifications for
transceiver components used in the XMP-Analog controller's I/O
are provided in tables below.
