High performance motor control is now available in ALTIVAR® 58 AC Drives!
Square D/Schneider Electric has extended the ALTIVAR® 58 AC
Drives' motor performance capability by combining the latest technology for closed loop flux vector control with the robust power section of
the ALTIVAR® 58 Type H AC Drive.This now completes the product
family, allowing high performance and general purpose with the same
power sections, size, interface, communication options, and hardware
options — the only difference is the main control board technology
with built-in encoder interface.
ALTIVAR® 58 FVC Flux Vector Closed Loop AC Drives are used for
precise speed control and optimum low speed torque performance of
three-phase asynchronous motors. Type FVC AC Drives are available
with a variety of operator interface options, I/O extension cards, and
communication cards. Ventilation and conduit entry options combined
with Type 1 construction provides installation flexibility for OEMs and
users installing AC Drives.
The production of a Pulse Width Modulation (PWM) waveform with a
closed loop flux vector control algorithm provides stable 100% torque
performance down to zero speed. It also provides excellent dynamic
speed response over a wide speed range (1:1000), with bandwidths
exceeding 50Hz.
ALTIVAR® 58 FVC AC Drives utilize the latest in drive technology by
incorporating Intelligent Power Modules (IPMs) containing Insulated
Gate Bipolar Transistors (IGBTs) and multiple ASICs in their design to
reduce parts count and improve reliability.
