This document provides instructions for the proper installation and use of the Yaskawa drive with “Safe-Off” option. This document is a supplement to the F7 technical manuals, and describes the effects on the drive functions and parameters when the “Safe-Off” option is installed. Read and understand this document as well as the standard drive technical manuals before attempting to install, adjust, operate, inspect or maintain the drive. -
Page 4: Overview
The Safe-Off option, when used with other safety components, provides protection according to EN954-1 Category 3 for safe stop and protection against restart. An F7 drive equipped with the Safe-Off option is just one component in a safety control system. To assure that the Safe-Off function appropriately fulfills the safety requirements of the application, a thorough risk assessment shall be done according to ISO12100 for the whole safety system at the final installation. -
Page 5: Basic Concept
The F7 with Safe-Off option is shipped from the factory with a jumper connecting BB and BB1 to SN. This jumper allows the F7 “out of the box” to operate as a conventional F7 drive without Safe-Off. The jumper must be removed to use the Safe-Off option. -
Page 6: Changes From Standard Product
BB and BB1 have the same opto-coupler interface as the other digital inputs, S1 through S8, and operate from the same isolated 24V on-board control supply. Whereas S1 through S8 connect only to the F7’s I/O processor, BB and BB1 also connect to hardware buffers that can block the gate drive signals to the IGBTs and prevent the motor from running. -
