The PowerFlex 75x-series provides a common set of features and options to help you maximize your investment and improve your productivity:

• DeviceLogix™ – Embedded control technology that supports the manipulation of discrete outputs and drive control functions, while using discrete inputs and drive status information onboard the drive.
• Predictive Diagnostics – Allows the PowerFlex 75x-series to keep track of information that affects the life of its cooling fans and relay outputs. The drive can also be programmed to monitor the run time hours for machine or motor bearings.
• Option Cards – Each drive has a slot-based architecture allowing you to build the drive to suit your application. Supported hardware control options are common for both products, to help reduce your inventory and spare parts requirements.
• Safe Torque-Off and Safe Speed Monitor – These safety options provide a choice for safety levels depending on your application requirements.
• Communications – The PowerFlex 75x-series supports a variety of network protocols. The PowerFlex 755 comes with a built-in Ethernet port. Ethernet can easily be added to the PowerFlex 753 with a communication module.
• I/O – The PowerFlex 75x-series offers option cards for additional analog and discrete I/O. The PowerFlex 753 comes with built-in I/O that can also be easily expanded with option cards.
• Packaging – Factory and field installable enclosure options are available to meet most environmental requirements: Open Type and Flange Mount options to support Cabinet Mount requirements, Extra Protection Wall Mount for harsh environments, and supporting debris hoods and conduit plate kits.
• Standard Power Structure – The PowerFlex 75x-series share a common power structure to provide the same physical footprint and power range no matter what PowerFlex 75x-series drive is used.
