Due to the limitation of the scan cycle, the ordinary counter in the Mitsubishi module FX2N-1HC has a low maximum operating frequency, generally only a few dozen KHZ, and sometimes exceeds this operating frequency in industrial applications.
Special function module of Mitsubishi module FX2N-1HC
Due to the limitation of the scan cycle, the ordinary counter in the Mitsubishi module FX2N-1HC has a low maximum operating frequency, generally only a few dozenKHZ, and sometimes exceeds this operating frequency in industrial applications. The high-speed counting module is designed to meet this requirement. It cancount pulsesKor evenMHZFX2Nis equipped with a high-speed counter inside, and the system is also equipped withFX2N-1HChigh-speed counter module, which can be used as2-phase50KHZone-channel high-speed counting. The counter can be reset or started throughPLCinstructions or external input. Its technical specifications are as shown in Table1shown.
