Selecting Power Supplies, Encoders, and
Drives
Overview In this chapter we explain how to select the hardware you need to
support an SLC Servo Module system. This chapter includes the
following topics:
•
Selecting a power supply for the backplane
•
Selecting a user-side power supply
•
Using fast inputs and outputs
•
Selecting an encoder
•
Selecting a drive
The amount of hardware you need depends on how many axes your
application uses. Consult your local Allen-Bradley sales engineer or
distributor to help you select the equipment for your application.
Selecting a Power Supply
for the Backplane Before you select a power supply, calculate the current requirements
for your backplane. Use the table below for SLC Servo Module
backplane current requirements:
In your calculations, include the current requirements of the I/O
modules in your chassis. Refer to your SLC 500 documentation.
IMPORTANT
The term user-side refers to the control circuitry on
the SLC Servo Module card that is powered by
customer-supplied power sources and isolated from
the control circuitry that is powered by the
backplane of an SLC rack.
