Rockwell Automation 284G ArmorStart - User Manual - Manual (Page 14)

1-4 Product Overview
The Bulletin 284G ArmorStart Distributed Motor Controller
incorporates, as standard, electronic motor overload protection. This
overload protection is accomplished electronically with an I
2
t
algorithm. The ArmorStart’s overload protection is programmable via
the communication network providing the user with flexibility.
Programming the Motor OL Current parameter provides class 10
overload protection for the Bulletin 284G Distributed Motor
Controller. Ambient insensitivity is inherent in the electronic design
of the overload.
