ATTENTION: Risk of injury or equipment damage exists.
Parameters 04 - [Idle Action 1], 19 - [Idle Action 2], and 34 - [Idle
Action 3] let you determine the action of the module and connected
drives if communications are disrupted. By default, these parameters
fault the drive. You can set these parameters so that the drive continues
to run. Precautions should be taken to ensure that the settings of these
parameters do not create a risk of injury or equipment damage. When
commissioning the drive, verify that your system responds correctly to
various situations (for example, a disconnected cable or a faulted
controller).

ATTENTION: Risk of injury or equipment damage exists. The
examples in this publication are intended solely for purposes of
example. There are many variables and requirements with any
application. Rockwell Automation, Inc. does not assume responsibility

ATTENTION: This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage Category II
applications (as defined in IEC publication 60664-1), at altitudes up to
2000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR Publication 11. Without appropriate
precautions, there may be potential difficulties ensuring
electromagnetic compatibility in other environments due to conducted
as well as radiated disturbance.
This equipment is supplied as “open type” equipment. It must be
mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately
designed to prevent personal injury resulting from accessibility to live
parts. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain
additional information regarding specific enclosure type ratings that are
required to comply with certain product safety certifications.
See NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure. Also, see the appropriate sections in this
publication, as well as the Allen-Bradley publication 1770-4.1
(“Industrial Automation Wiring and Grounding Guidelines”), for
additional installation requirements pertaining to this equipment.
