1 INTRODUCTION TO THE CRANE
The applicative for crane developed for the CFW500 SoftPLC function provides flexibility to the user in the
system use and in its configuration. It uses the tools already developed for the WLP programming software,
together with configuration wizards and monitoring dialog boxes.
DANGER!
Crushing Hazard
In order to ensure safety in load lifting applications, electric and/or mechanical devices must be
installed outside the inverter for protection against accidental fall of load.
DANGER!
This product was not designed to be used as a safety element. Additional measures must be taken
so as to avoid material and personal damages.
The product was manufactured under strict quality control, however, if installed in systems where its
failure causes risks of material or personal damages, additional external safety devices must ensure
a safety condition in case of a product failure, preventing accidents.
1.1 CRANE VERTICAL MOTION
The crane vertical motion consists in moving the load vertically by executing commands to move it up and
down. The load hoisting and its lowering are the vertical motions.

1.2 CRANE HORIZONTAL MOTION
The crane horizontal motion (or load translation) consists in moving the load in the horizontal direction by
executing commands to forward and reverse the load. The long travel, the cross travel, and the boom rotation,
among others, are horizontal motions.
