High Speed Outputs
Pulse Train Output Positioning control with servo motors and stepper motors is possible without specialized units. High Speed Outputs In PLCs that have transistor outputs, the terminal for output bits 0 and 1 can be used not only as a usual external output but as pulse output with up to 10kHz. The pulse output can be operated with dedicated instructions, allowing easy control based on pulse train output and pulse width modulation.
The High-speed Output (HSO) generates output pulse trains suitable for open-loop control of a single-axis motion positioning system. It generates pulse (stepper increment) and direction signals which you can connect to motor drive systems and perform various types of motion control. Error detection can be available by using the high-speed counter in combination. Unexpected incidents, such as errors in the driving system, can be detected by setting the counter so that it counts the feedback pulses from an encoder during positioning. Simple positioning control, fine tuning of conveyor’s moving distance, etc. are possible by pulse train output.

Programm can be combined to create an application for counting pulse signals from the encoders through the high-speed counter inputs and adjusting the pulse output frequency based on the count to synchronize the slave axis speed with the master axis speed.

The speed of conveyor 1 is measured based on the Master encoder pulse count, and pulses are output to the stepper motor according to the measured speed in order to synchronize the speed of conveyor 2.
