Shrink machine switch control

Release date:2016-08-04 Author:admin Click:

What is the working process of the shrinking machine? What are the switching controls for the shrinking machine? How can we ensure that our machines can be better produced after we have purchased machinery and equipment? What are the control buttons for the shrink machine? What's the function of the switch button?

        There are two kinds of open-loop control: one is program control and the other is proportional control。

Program control means that once the control command is initiated, control will be performed according to a predetermined program to allow the moving part to move at the required speed, acceleration control, or trajectory until the control task is completed.

Proportional control means that one pulse output (control quantity) tracks another input quantity change, also called follow-up control or synchronous movement。 The biggest advantages of open-loop control are simplicity, fast response, and no system instability。 Therefore, NC also uses open-loop control。

Open-loop control is used for positioning and motion control with single-axis, dual-axis, and multi-axis。 Minicomputers are mostly used for single-axis or dual-axis control。

The following sections discuss single-axis position control, single-axis acceleration and deceleration position control, single-axis multi-segment position control, and multi-axis coordinated motion control。

On a single axis (a coordinate), when a work order is issued, the part can be caused to complete the specified displacement (specified pulse number) displacement at the specified speed (specified pulse frequency), which is referred to as “position control” here。

The hardware that makes up such a system can be a small PLC, a stepper motor, and ancillary facilities and moving parts.
