AirCare Full Feature EC™ ACM1021 for NIDEC smart-motors is a robust variable-speed controller intended for brushless DC (BLDC), electrically-commutated (EC) motors. The ACM1021 Series combines intelligent speed control with industry standard MODBUS networking. The versatile design allows for analog (0- 5V or 20mA current loop) or network control input and analog or tachometer feedback. Precise control is possible over a wide speed range (1-100%).
ACM1021 closed-loop control (CLC) capability supports a wide range of sensors such as air pressure, air flow and temperature. In closed-loop mode, ACM1021 adjusts motor speed to converge the value of a selected feedback source to the set-point value.
