Power rating
- 0.5…25 Hp output at 240V AC input
- 0.5…50 Hp output at 480V AC input
- 0.5…50 Hp output at 600V AC input
Features
- The PowerFlex 70 drive can be used with a full featured LCD human interface module (HIM) that provides multilingual text for startup, metering, programming, and troubleshooting.
- The PowerFlex 70 can be programmed for either volts per Hertz, sensorless vector, or vector control with FORCE Technology to cover a wide range of applications from fans to extruders.
- Optional internal communication modules provide fast and efficient control and/or data exchange with host controllers over popular interfaces. These interfaces include: Connected Components Workbench™ software, DeviceNetManager™, EtherNet/IP®, ControlNet®, serial communications, and other open control and communication networks. Computer tools such as DriveExplorer™ and DriveTools™ SP assist with programming, monitoring, and troubleshooting the PowerFlex 70.
Easy to Use Human Interface Tools
The PowerFlex 7-Class AC drives provide common human interface tools that are familiar and easy to use. These tools include the LCD human interface modules and computer-based configuration tools.
The LCD HIMs provide these features and functions:
- Large and easy to read 7-line x 21-character backlit display
- Variety of languages (English, French, German, Italian, Spanish, Portuguese, Dutch)
- Alternate function keys for shortcuts to common tasks
- ‘Calculator-like’ number pad for fast and easy data entry (full numeric version only)
- Control keys for local start, stop, speed, and direction
- Remote versions for panel mount application
Outstanding Control and Performance
- Volt/Hertz Control for simple Fan and Pump applications
- Vector Control with FORCE Technology provides outstanding torque and speed regulation, with or without encoder feedback.
- Sensorless Vector Control develops high torque over a wide speed range, and adapts to individual motor characteristics.
Drives Features
- Fast acting Current Limit and Bus Voltage Regulation result in maximum acceleration and deceleration without tripping.
- Flying Start delivers smooth connection into rotating loads, regardless of commanded direction, without the need for any speed feedback device.
- PI Control can eliminate the need for a separate process loop controller.
- Inertia Ride-Through offers tripless operation during a prolonged power outage by using the rotating energy that is stored in
high-inertia, low-friction loads. - User Sets, allowing up to three complete sets of parameter data, can be individually loaded for different batch processes.
- Slip compensation delivers minimum of 0.5% open-loop speed regulation across a wide speed range, eliminating the need for speed feedback devices in some applications.
- Safe Torque Off, the first offering available within the DriveGuard® series of safety solutions, helps prevent a drive from delivering rotational energy to motors by integrating a safety circuit with the power switching signals of the drive. This solution meets EN ISO 13849-1, Category 3.
- Droop Control for load sharing applications.
- Sleep/Wake Control for analog control of start and stop.
