Inovance MD300 User Manual

MD320/MD320N User Manual Preface
3
1) The bottom-layer module of the MD series inverter is high-performance motor control
module and consists of V/F, speed sensorless vector control (SVC) and vector control. It is
mainly responsible for high performance control and overall protection of the motor, controlling
the motor through sending running commands to multiple channels or performing close loop
vector control through encoder interface.
2) The middle-layer module of MD series inverter is general functional module, which mainly
includes some basic functions of the inverter, such as PID control, MS speed, and swing
frequency and so on. According to the degree of complexity of functions, Inovance Technology
provides two sub-modules for options of the customers, that is, MD320 functional module and
MD300 functional module. Refer to Table 1 for the difference between the two modules.
