MC3PHAC/D
Introduction
10
The MC3PHAC is a high-performance intelligent controller designed
specifically to meet the requirements for low-cost, variable-speed,
3-phase ac motor control systems. The device is adaptable and configurable,
based on its environment. Constructed with high-speed CMOS
(complementary metal-oxide semiconductor) technology, the MC3PHAC offers
a high degree of performance and ruggedness in the hostile environments
often found in motor control systems.
The device consists of:
The serial communications interface is used in a mode, called PC master
software mode, whereby control of the MC3PHAC is from a host or master
personal computer executing PC master software or a microcontroller
emulating PC master software commands. In either case, control via the
internet is feasible.
Included in the MC3PHAC are protective features consisting of dc bus
monitoring and a system fault input that will immediately disable the PWM
module upon detection of a system fault.
