System Overview
The PowerFlex® 755 On-Machine™ Drive is a small footprint UL Type 12 /
IP66 (indoor use only) enclosure. It offers several configurations for encoder
feedback, Safe Torque Off, and the Network Integrated Safety Function. The
product also includes quick-connect connections for: I/O, power, motor,
safety, encoder feedback, positioning, communication, and brake connectors
on the bottom gland plate.
The drive is designed for automotive and material handling customer
applications, including: cart transfer tables, framers, power roll beds,
trunnions, turntables, and vertical lifts.
The EtherNet/IP® communication utilized by the drive allows use with the
following network topologies: linear, star, and Device Level Ring (DLR).
There are two safety options available for the drive:
• Safe Torque Off (20-750-S3) - Safe torque off for safety-related
applications that require the removal of rotational power to the
motor without shutting down the drive.
• Network Integrated Safety Function (20-750-S4) - The integrated
safety function option combines Safe Torque Off capability and the
safe speed control technology in one hardware option.

IMPORTANT The safety option module is intended to be part of the safety-related control
system of a machine. Before installation, perform a risk assessment to
determine whether the specifications of this safety option module are
suitable for all foreseeable operational and environmental characteristics of
the system. The software versions that are required for the two available
safety options are different. See the
