PowerFlex 525 AC Drive Specifications
Communications
• Embedded EtherNet/IP™ port allows easy configuration, control, and collection of drive data over the network.
• Dual port EtherNet/IP option card supports Device Level Ring (DLR) topologies, providing fault-tolerant
connectivity for optimum drive availability.
• Integral RS485/DSI communications enable the drives to be used in a multi-drop network configuration.
• Optional communication cards such as DeviceNet™, and PROFIBUS DP™ can improve machine performance.
• Field installed option allows for future addition of stand-alone drives to a network.
• Online EDS file creation with RSNetWorx™ providing ease of set-up on a network.
Closed Loop
Encoder/Pulse Train Input Standard
The PowerFlex 525 drive allows for configurable closed loop control with an optional encoder card for either speed or
position feedback for improved speed regulation, basic position control, or other pulse inputs for motor control.
• Improved speed regulation
• Basic position control
Basic Position Control
Local Position Control
• Position regulator with StepLogic™
• 8 positions (local logic)
Outer Position Control Loop
• Analog input bipolar mode offers improved zero-cross performance.
• Simple motion control applications with more complex position profiles.
• Speed reference supplied to drive via Analog Input or multiple field bus network options.
• Speed ratio available for simple draw applications.
