functionality of the SP600 AC drive is presented with an intuitive human
interface, which features a large graphical LCD display and icons depicting
functional groups for the user to select. These icons provide a simple method
of locating and accessing drive variables. The benefits become clear as the
user easily maneuvers through parameter groups and feature sets that are
clearly identifiable on the display in six languages.
four independent function keys on the keypad that each can be assigned two
separate functions by the user, allowing a total of eight separate operations.
Operations include preset speed commands, auto/manual reference selection for
speed control, and fault log access. These are included to help the user save
time and eliminate the need to hardwire switches or navigate through the
drive’s parameter structure.
can choose either Sensorless Vector Control (SVC) or V/Hz operation. The SVC
operation offers advanced performance by providing optimum torque production at
very low speeds — including operation at 0.0 Hertz (0 RPM). Predictable, broad
constant torque performance is the key attribute of the SP600 AC Drive for
single motor, constant torque applications. Motor overload protection is
scalable up to 400% of the motor’s full load amp rating for PowerMatched™
enclosure configurations allow optimization of the drive’s use in specific
environmental applications. Users can choose from NEMA 1 and NEMA 4X/12 wall
mount enclosures. The NEMA 4X/12 enclosures are designed to provide protection
during washdown in food processing applications by withstanding spray pressures
up to 1,000 psi at 6 inches while also complying with NSF 51 and FDA
guidelines. Dust particles as small as 22 microns also are prevented from
entering the drive, providing contamination-free operation even in very severe
consider the SP600 flange-mount design for added space savings when mounting
into a cabinet. NEMA 1 enclosures can be converted to IP20 for flange-mounted
installations increasing ambient operation to 50°C. The heatsink exits the rear
of the cabinet for external heat dissipation, reducing hardware installation
costs by eliminating the need for auxiliary cooling fans or air conditioning.
drive also features standard snubber brake circuitry and optional snubber
braking resistor kits that can be mounted directly onto the back of the drive’s
heatsink. This is very useful for handling speed overshoot or motor
regeneration conditions that can occur during fast speed changes.
operations efficiency, the SP600 is designed for smooth integration into
virtually any manufacturing process. Network status is clearly displayed on the
cover by four separate LEDs, making communications status easy to identify.
