The F7 general purpose AC drive is designed and built to be an industrial workhorse capable of handling various industrial plant applications. The drive uses a flexible design platform to provide both normal and heavy-duty ratings, four modes of control, network communications options, application-specific drive software, and a range of standard and optional input/output choices. It's globally compatible, conforming to UL, cUL, and CE requirements.
The BHF series of 50/60 Hz AC motors is designed with inverter speed control and low-noise pre-assembled gearheads. The gearmotor shaft torques range from 14.1 lb-in. to 530 lb-in., depending on gearhead type and shaft speed. The series is available with an electromagnetic brake for applications with vertical motion. Three input voltage ranges are available for all models: single-phase 100VAC to 115VAC, single-phase 200VAC to 230VAC, and 3-phase 200VAC to 230VAC. The inverter provides speed stability for speeds from 100 rpm to 2,400 rpm, and it has a built-in I/O power supply.

The ArmorStart is a pre-engineered, pre-configured combination motor starter that requires no additional enclosures and features a modular, plug-and-play design for quick installation. The integrated, machine-mount design uses fewer cables, which simplifies wiring, minimizes panel space requirements, and allows faster and more accurate connections. The device can be used with motors ranging from .5 hp to 10 hp at 50 Hz to 60 Hz for non-reversing and reversing applications with a voltage range from 200VAC to 460VAC.
Adjustable speed AC drive
The Altivar 58 TRX AC drive incorporates sensorless vector control and enhancements to adjustable speed drives. The drive features built-in connectivity that simplifies the exchange of equipment and processes information. With an Ethernet option card, embedded Web pages allow real-time access to drive information from anywhere in the world using a standard Web browser. They're available with a variety of operator interface options, I/O extension cards, and communications options cards.
Square D/Schneider Electric
The PST series of softstarters is available for operating voltages from 208VAC to 690VAC and full load line currents of 30A to 1,050A. When used with wye-delta wound motors, the softstarters are capable of inside-the-delta operation and are UL Listed for starting motors up to 1,800 hp. They use a large 2-line graphical liquid crystal display (LCD) to provide plain text communications in any one of 12 user selectable languages. They also offer machine-to-machine networking.
The S10 AC drive provides .25 hp to 3 hp 115V, 230V, and 460V single- or 3-phase input for applications like fans, blowers, and conveyors. The drive has two types of enclosures, IP20 (protected chassis) and IP65 (NEMA 4X) with and without operators to match most application needs. The NEMA 4X units with operators come with standard input disconnect, speed pot, and forward/reverse selector switch. The drives feature V/Hz PWM control, 16 kHz carrier frequency, and are UL, cUL, and CE approved.
AC and DC drives
The VersaFlex line of AC and DC drives features protected chassis enclosures, selectable feedback with option boards, auto-tune, and application programs. The AC inverter drives are available in open-loop configurations of .33 hp to 2 hp, 198VAC to 264VAC, single-phase, 50/60 Hz; 3 hp to 5 hp, 198VAC to 264VAC, 3-phase, 50/60 Hz; and .5 hp to 10 hp, 342VAC to 506VAC, 3-phase, 50/60 Hz. The AC drives can be applied to variable torque, constant torque, or constant horsepower applications.

AC drive communications software
This Windows-based software communications programs enables AC variable frequency drive users to configure, start-up, tune, and perform diagnostic services on their drive or drive system. Built-in features of the software tools include user-friendly graphics to make it easy to monitor and control drive performance. They also offer visual set-up with help menus, a real-time oscilloscope with trend recorder, a PID tuner, and customizable monitor panels. The software runs under all versions of Windows, from 98 to XP.
Baseblock Software Corp.
The AF-300 Mini adjustable frequency AC drive is designed for optimum process control and offers variable speed control for AC induction motors. It features a predictive maintenance alarm that can be custom-wired to a pilot light or programmable logical controller and can signal an alarm when the cooling fan or internal DC link capacitor has nearly reached its specified wear-hour lifespan. The drives require less mounting space, allowing for flush, side-by-side mounting.
