There are many similarities between the RMC controllers, including the RMCTools software for set up and programming. However, the correct product choice will depend on how many axes your application requires.

Application examples for RMC motion controllers include industrial motion applications such as assembly, packaging, material handling, and machine tools.

Whether you need to control a single-axis or multi-axis system, a simple or complex application, or a new or existing system, the RMC motion controllers can meet your needs with ease. It is also valuable to mention that all RMC controllers are backed by Delta’s responsive 24/7 customer support.

The RMC motion controllers are a versatile and powerful solution for industrial motion control applications. With their advanced features, high-speed performance, and flexible programming options, the products provide precise and efficient control while being easy to integrate and customize. Whether you need to control one or multiple axes, the RMC motion controllers can provide the precision and reliability required for your application.

Do you like or need instant results? In our current world, everything is getting faster and more precise. That is driven by both our needs and expectations. We want and need better.

PID – why do I care? I hated math in High School and College. I found it tedious and no one could give me a good reason why I was slogging through it. Formulas, theorems, proofs. Why bother? There was no good reason that I could find. So I didn’t care. More on that in a bit.

In the industrial or process world, to control our processes and machinery we commonly use a PLC (programmable logic controller) or some form of a PC. These are pretty powerful tools and do a great job of keeping our processes in order (the logic portion of the PLC) as well as collecting and reporting the data.

Unfortunately, nothing in this world is instant. Everything lags behind the desired or asked for command. So when you ask your machine for something, and then compare it to what actually happened, there is a time lag and performance lag. These lags are called error.

The big question is “what are you, or can you do about it?” (Wait, I though the question was “What is PID and why do I care?” I do like things with lots of power and speed and I do like to be right on the edge of control.) The better your system needs to be, typically the more time and effort it takes. When you want minimal to no error in controlling:

• Pressure or force
• Controlling velocity or flow
• Position
• Or any of the above simultaneously

This is when you need the right tool for the job. You need a dedicated motion controller.

The motion controllers sole job is to look at the desired activity, compare it to actual and utilize all the power and speed available to make corrections. This control process is called closing the loop or “closed loop”. It is part of the definition of servo or proportional control.

Here is where the math – P proportion I integral D derivative come into play and the Delta motion controller is the tool to do it. In a system, the desired input comes from the PLC, the motion controller compares the “go” command to the power available along with the reaction time of the system, and creates an output package that executes the result as close to the desired as possible.

The input and actual result can be graphed. One of the axis of this graph is time, and the other is the object you are trying to control. Once you graph it, it becomes a mathematical expression (formulas that I hated…). How often you look at the error and make a correction is a big part of error correction. The Delta can look at actual vs desired as many as 4,000 times per second. (The best most PLC’s can do is approximately 250 times per second. Also, PLC’s were meant for sequential steps – logic. Their processors were not meant for crunching math) The Delta has many other powerful math tools besides basic PID to correct for error and improve performance.

So what can we do with this Delta controller? First it is part of a system, so you need the whole system designed correctly for the end result. This is where Donald’s staff comes in to help you build the system you need to attain your goals.

Would like to move a cylinder to a destination quickly, without over shoot, and land on your dimension with a tolerance of + 0.000” / - .003” ? we do that regularly (and better).

Would like to take your 80 ton press and control force within a few pounds while moving quickly at a controlled speed to a destination (closing the loop on velocity and force, then distance and force simultaneously)? We do that regularly.

Not everybody needs high performance and control. But when you need it, you need Donald Engineering and Delta.
