How does the PLC control the electronic handwheel?
It's OK to use high-speed counter control. Measuring the number of pulses of handwheel with high speed counter.
The general PLC is not good, there can be hand wheel PLC or module, easy to use.
With high-speed counter control, you can use a high-speed counter measuring the number of hand wheel pulse.High speed counter refers to calculate the pulse signal faster than ordinary scanning frequency, its working principle and common counter similar, just count the channel response time is shorter, with the frequency of KHZ to count, such as precision is 20KHZ.The current value of the high-speed counter is a double word length (32 bit) integer, and is read only. In S7-200 PLC, HCO and so forth are often used to represent and calculate.
