Safety Configurations
The PowerFlex 700S drive was available with an optional hardware Safe Torque
Off / 2nd Encoder module. The functionality of this option can easily be
obtained with the PowerFlex 755T product by using one of the available Safe
Torque Off option modules. If the optional 20-750-S3 Safe Torque Off
module is installed, the PowerFlex 755T can be used with Integrated Safety
over EtherNet/IP.
PowerFlex 700S Safety Options
The PowerFlex 700S DriveGuard® Safe Torque Off with 2nd Encoder option
module, catalog 20D-P2-DG01, provides hardware Safe Torque Off
functionality and the facility to connect a second encoder. The DriveGuard
option requires an Expanded Cassette.
The DriveGuard Safe Torque Off option is just one component in a safety
control system. Components in the system must be chosen and applied
appropriately to achieve the desired level of functional safety.
Details of installation, wiring, and safety performance levels are found in the
DriveGuard Safe Torque Off Option for PowerFlex 700S Phase II AC Drives
and PowerFlex 700L Liquid-Cooled AC Drives User Manual, publication
