PowerFlex 527 AC Drive Specifications
• A jumper to switch between 24V DC sink or source control for control wiring flexibility.
• Dual Overload Rating available for drives above 15 HP/11 kW. Normal duty: 110% overload for 60 seconds or
150% for 3 seconds. Heavy duty: 150% overload for 60 seconds or 180% overload (200% programmable) for
3 seconds provides robust overload protection.
• Adjustable PWM frequency up to 8 kHz ensures quiet operation.
PowerFlex 527 AC Drive Advanced Features
Control Performance
• Frequency Control with the following options:
• Volts per Hertz (V/Hz)
• Sensorless Vector Control (SVC)
• Sensorless Vector Control (SVC) Economizer
• Position Loop, including:
• Closed Loop Position Vector Control (with optional encoder card)
• Velocity Loop, including:
• Closed Loop Velocity Vector Control (with optional encoder card)
I/O Wiring
• Two (2) Analog Inputs (one current and one voltage)
are independently isolated from the rest of the drive
I/O.
• Four (4) Digital Inputs provide application versatility.
• One (1) Analog Output is jumper selectable between
either 0-10V or 0-20 mA. This scalable, 10-bit output
is suitable for metering or as a speed reference for
another drive.
• Two (2) Opto Outputs and two (2) Relay Outputs
(one form A and one form B) can be used to indicate
various drive, motor or logic conditions.
Communications
• Built-in dual port for EtherNet/IP allows easy
configuration, control, and collection of drive data over
the network. It also supports Device Level Ring (DLR)
topologies, providing fault-tolerant connectivity for
optimum drive availability.
• Online EDS file creation with RSNetWorx™ providing
ease of set-up on a network.
