The PowerFlex 700H: High-Performance Drives for Demanding Environments

The PowerFlex 700H series sets a benchmark in high-performance drives for demanding industrial environments. This drive series, renowned for its superior flexibility, robust design, and advanced control features, offers exceptional speed control and programming capabilities. With a wide array of power ratings and configurations, these drives are manufactured to integrate different application needs, from heavy-duty machinery to precision motor control. The PowerFlex 700H series ensures reliable operation, efficient performance, and easy incorporation into different industrial systems, making this series a good choice for complex and challenging operational demands.

Voltage Ranges and Power Ratings:

The available ratings for this drive series are 200 to 1900 HP at 480 Volts AC, 150 to 2400 Horsepower at 600 Volts AC, and 160 to 2000 kW at 690 Volts AC input. Due to their wide power and voltage ranges, these drives are ideal for a wide range of industrial applications.

Module for Human Interface (HIM):

This drive series has a full-function LCD HIM with a 7-line by 21-character back-lit display. Programming is made simpler by the multi-line, multilingual display, which supports Portuguese, English, Italian, German, Spanish, Dutch, and French, among other languages. A “calculator-like” number pad (Full Numeric version) enables quick and simple data entry, while other function buttons offer shortcuts to frequently used activities. Control keys make issuing local commands for direction, speed, and start/stop easier.

Modes of Control:

The PowerFlex 700H includes both Sensorless Vector and Volts-per-Hertz control functions. The drive’s control choices make it easy to satisfy various application requirements, guaranteeing peak performance for different motor kinds and operating environments.

Detachable Control Unit:

The PowerFlex 700H’s control module may be removed independently from the power structure. Because of this design feature, users may handle the control module independently of the drive’s power components, which simplifies installation and maintenance.

Optional I/O Modules:

Optional I/O modules for the PowerFlex 700H are offered in 24V DC or 115V AC variants. These modules increase the drive’s capability and adaptability by providing more options for tailoring it to meet the needs of certain applications.

Internal Communication Modules:

For the PowerFlex 700H, user-installed kits are offered for internal communication modules. These modules provide quick and effective control and data interchange with host controllers through interfaces such as Profibus, Ethernet/IP, DeviceNet, ControlNet, and more.

Applications for Panel Mount and Remote:

For panel mount applications, the LCD HIM has remote variants that enable flexibility in installation and operation. This improves the user experience by enabling easy access and control in different industrial settings. S.M.A.R.T, which are the HIM’s start and assisted startup protocols, streamline drive tuning and setup, enabling users to set up and optimize the drive for certain applications quickly.

Simple Wiring and Fast Disconnection:

Pull-apart control terminal blocks, a feature of the PowerFlex 700H, make it simple to wire and quickly separate I/O cabling. This feature allows professionals to rapidly and safely disconnect and reconnect wires without affecting the integrity of the drive’s connections, which streamlines installation, shortens setup times, and enables maintenance.

Meeting Industrial Standards:

This drive series, which has comparable PowerFlex 700S Alternating Current drive ratings, combines industry-standard packaging with a modular architecture and a high level of power structure commonality. This design streamlines maintenance and improves operating efficiency by reducing the need for large spare parts inventories. Standard cabinet designs (frame-10 and bigger) are offered for small drive applications or multi-drive lineups, and they can be easily placed on the floor. Furthermore, these drives may be found in IP21/UL Type-1 (NEMA-1) and IP54/UL Type-12 (NEMA-12) containers, accommodating different environmental circumstances. NEMA-1 or NEMA-4/12 operator interfaces can also be installed inside or through doors. For all ratings, a line reactor on the AC input is provided, improving drive protection and functionality.

Working in Different Environmental Scenarios:

The PowerFlex 700H drives are engineered to function optimally in particular environmental scenarios. They can operate without derating at altitudes of up to 1000 m (3300 feet) and continue to work at their peak efficiency in different ambient air temperatures, depending on the drive rating. -40 to 60 degrees Celsius (-40 to 140 degrees Fahrenheit) are the range of storage temperatures. If these drives are not installed immediately, they must be stored in non-corrosive conditions. These drives should not be placed in locations containing volatile or corrosive fumes, vapors, or dust. They can tolerate 2.0 mm displacement vibration at 1G peak, 15G peak shock for 11ms duration, and 5%-95% humidity.

Now, we will be discussing some of the example modules of this series:

20CD300A0ANNBNA0 Module:
