Throughout this manual, the following notes are used to alert you to safety considerations:
Important: Identifies information that is critical for successful application and understanding of the product.
The thick black bar shown on the outside margin of this page will be used throughout this instruction manual to
signify new or revised text or figures.
!
ATTENTION: Identifies information about practices or circumstances that can lead to personal
injury or death, property damage, or economic loss.
!
ATTENTION: Only qualified personnel familiar with the construction and operation of this
equipment and the hazards involved should install, adjust, operate, or service this equipment.
Read and understand this manual and other applicable manuals in their entirety before
proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: DC bus capacitors retain hazardous voltages after input power has been
disconnected. After disconnecting input power from the DC bus supply, wait five (5) minutes and
then measure the voltage at the POS and NEG terminals of the DC bus supply and each Power
Module to ensure the DC bus capacitors are discharged before touching any internal components.
Failure to observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: For brushless motor applications, changing any resolver wiring, breaking the
resolver coupling, replacing the resolver, or replacing the motor and resolver for any reason
requires that the shaft alignment test be performed again. Resolver wiring changes always affect
shaft alignment. A resolver change and/or a new motor/resolver combination will affect the shaft
alignment. Improper shaft alignment can cause motor overspeed when the motor is started. Failure
to observe this precaution could result in bodily injury.
ATTENTION: The user must provide an external, hardwired emergency stop circuit outside of the
drive circuitry. This circuit must disable the system in case of improper operation. Uncontrolled
machine operation may result if this procedure is not followed. Failure to observe this precaution
could result in bodily injury.
ATTENTION: Inserting or removing a module or its connecting cables may result in unexpected
machine motion. Turn off power to the rack before removing a module or its connecting cables.
Failure to observe these precautions could result in bodily injury.
ATTENTION: Only qualified Rockwell personnel or other trained personnel who understand the
potential hazards involved may make modifications to the rack configuration, variable
configuration, and application tasks. Any modifications may result in uncontrolled machine
operation. Failure to observe these precautions could result in damage to equipment and bodily
injury.
ATTENTION: Registers and bits in the UDC module that are described as “read only” or for “system
use only” must not be written to by the user. Writing to these registers and bits may result in
improper system operation. Failure to observe this precaution could result in bodily injury.
ATTENTION: The user is responsible for conforming with all applicable local, national, and
international codes. Failure to observe this precaution could result in damage to, or destruction
of, the equipment.
