116 / 179 page  116/179 ST92141 - 3-PHASE INDUCTION MOTOR CONTROLLER (IMC) 7.4 3-PHASE INDUCTION MOTOR CONTROLLER (IMC) 7.4.1 Introduction The IMC controller is designed for variable speed motor control applications. Three PWM outputs are available for controlling a three-phase motor drive. Rotor speed feedback is provided by captur- ing a tachogenerator input signal. 7.4.2 Main Features s 10-bit PWM Up/Down Counter s Classical and zerocentered PWM operating modes s Full-scale PWM generation s 6-bit dead time generator s Rotor speed measurement s 8 interrupt sources + 1 NMI 7.4.3 Functional Description The IMC controller consists of the following func- tion blocks: – Input and Output pins – Rotor speed measurement – 3-Phase PWM signal generation – 6-bit Dead Time generation – Polarity selection – Interrupt generation The block diagram is shown in Figure 63.
