Through the PLC pulse control stepper motor, but how to control his speed, my speed dimension is /MIN. I'm using OMRON's PLC. I don't know how to control the speed. Is there any formula? I hope everyone will give an opinion
Stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle called the step angle",
1600, the subdivision is exaggerated, but also the lack of parameters.Take the 1600 subdivision, assuming that your step angle is 1.8 degreesPulses per cycle are required1600X360/1.8=320000Your pulse output reaches 320000 seconds per second, and your speed is 60 revolutions per minute,There is no need to measure, step in without losing step, basically no accumulated error, need to measure accurate, need to add encoder or induction head, if not grating ruler, those are not worth, not as good as servoIn this way, you see, no, or do not understand, leave a message for me
It rotates at a fixed angle, step by step. Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
The PLC can measure the speed of a stepper motor by either an encoder or a tachometer generator.The stepping motor is an open loop control element which transforms the electric pulse signal into angular displacement or linear displacement. In the case of non overloading, the motor speed,
