Tips: Digital counter application in digital system
Counter is typical sequential logic circuit and also is the most used sequential logic devices in digital systems. Using a digital counter to count pulses or conduct fractional frequency can achieve measurement, calculation, timing control and other functions. In addition to the counting function, the counter also has functions such as asynchronous reset, preset parameter, and hold. The preset function is divided into two kinds: synchronous preset and asynchronous preset. The former is controlled by timing pulses, and the later is not controlled by timing pulses. The hold function is also divided into two types: hold-carry and hold without carry. The counter can also be used as a sequential pulse generator.

In this video, ATO will show you how to wire a digital counter. And how to set the basic parameters of digital counter.

Digital Counter and Proximity Sensor Counting

Choice of digital counter

I am looking for information on how I would use your photoelectric sensor and digital counter to stop a vfd when it hits a predetermined count. Is there a support forum for this of scenario?

From: Miegel | Date: 14/05/2021

Was this review helpful? Yes No (0/0)

ATO Responded

Yes, simply, when ordering the digital counter, select output relay option from pull down menus. Our VFD has multi-function terminals X1, X2. So just connect output relay terminals to VFD "X1 & COM" and define XI as free stop, so can stop VFD when the digital counter hits a predetermined count as pre-programmed.
