Chapter 2 Drive Configuration
PowerFlex 755T Safety Options
Like the PowerFlex 750-series AC drives, the PowerFlex 755T can be equipped
with one safety option module. The safety option module is just one
component in a safety control system. Components in the migration solution
must be chosen and applied appropriately to achieve the same or higher level of
functional safety that was available with the existing PowerFlex 700S with
DriveGuard Safe Torque Off.
Details of installation, wiring, and safety performance levels for each of the
PowerFlex 750-series safety options can be found in Ta b le 6 6
.
Migration Solutions
Either the hardware Safe Torque Off (20-750-S) or integrated Safe Torque Off
(20-750-S3) PowerFlex 750-series safety options can be used to migrate the
functionality of the PowerFlex 700S DriveGuard Safe Torque Off module.
The PowerFlex 750-series Safe Torque Off option modules exclude encoder
inputs. If the second encoder part of the PowerFlex 700S DriveGuard Safe
Torque Off module is used, it will be necessary to supply a PowerFlex 750-
series encoder option module to interface with the second encoder.
The PowerFlex 700S DriveGuard Safe Torque Off requires using the
DriveGuard safety module feedback monitoring contact to achieve the
published safety level and category. The PowerFlex 750-series safety modules
do not use or require safety module feedback monitoring to achieve the
published safety level and category.
The integrated Safe Torque Off option module (20-750-S3) uses integrated
safety over EtherNet/IP or a hardware interface for Safe Torque Off
functionality.
See Actuator Subsystems – Stop Cat. 0 or 1 via a PowerFlex Drive with
Integrated Safe Torque Off Safety Function Application Technique,
publication SAFETY-AT141
, that describes using the PowerFlex 750-Series
integrated Safe Torque Off option module.
