The factory where I first started working was all controlled by relay logic. To change to PLC logic all the switches etc would be wired to inputs and all the motors etc would be wired to outputs via contactors. Post the electrical schematic so we can see how complex the circuit is.

If this is a cylinder with a short stroke, make sure the reed switches is properly adjusted so it will reliably turn off. Otherwise I would be getting someone to check the cylinder to see if the magnet is damaged or replace the cylinder altogether.

See detail in OP, measured length: 510 to 520 (too high), actual length: 485

Please provide more information. Are they signal splitters or signal isolators? What is the make/model of this device? Disconnect the wires from the + and - terminals on the device and measure DC voltage on these terminals, should be around 24VDC if this has it’s own power supply.

The drive parameters you mentioned in your original post seem to be correct. Short term currents higher than the name plate current are normal for a lot of motor applications. The tripping of motor protection is based on current and time, it will not trip instantaneously when the name plate...

I2t and thermal protection are the same thing, just not mentioned by I2t in the ACS manual. With 30.05 set to DTC, the drive automatically calculates motor thermal time and motor load curves for the motor thermal model. When the model thinks the motor has reached 95% of the temperature limit a...

As 30.05 is set to DTC the motor temperature is estimated by the VSD. Do you have any temperature sensors on your motor? normally the bigger and more expensive a motor is, the more you spend on protection to make sure you don't break it. 30.06 is only used if 30.05 is set to user mode, so this...

You’re welcome Tahoe. I have used ACH580 which have some common parameters with the ACS. What value are the parameters Motor Thermal Protection, 30.04 and Motor Therm P Mode, 30.05? Do you expect the motor to be overloaded for short periods of time due to variations in the mechanical load? The...

What value is the motor nominal current parameter, 99.06?

Glad we could help you solve this problem. The forum is here for people to ask any question. To quote Carl Sagan, "There are naïve questions, tedious questions, ill-phrased questions, questions put after inadequate self-criticism. But every question is a cry to understand the world. There is no...

The way you have calculated the ratio is opposite to what I stated so it will be a divisor for the length: 3*3.14157 *100 /1.2083 /12 = 65.016 feet

I presume the face of the felt against the guide roller is not distorting/stretching as it passes by, but the face of the felt against the encoder wheel will be temporarily as it takes a longer path. Try dividing the guide roller circumference by the guide roller circumference with felt wrapped...

If a 3 phase motor has six wires at the terminal box it can be connected in star or delta, the voltage suitable for each option would be on the name plate. If there is only three wires then it is only suitable for one voltage which would also be on the nameplate. Generally if you have a 230V...

Google the getting started manual for the Siemens PLC or software you want to use, also YouTube. The steepness of the learning curve all depends what your programming experience in general you have and how easily you can adapt to PLC.

The square output voltage is an artificial sign wave, to create the required RMS voltage. Generally if you are talking about a 3 phase system you would be referring to line to line voltage, there is not a single reference point for your output voltage, measure line to line RMS voltages. This is...

Generally the maximum RMS voltage you get out of an inverter is the same as you put in. From your example, case 2) is correct but a complicated way to say: 400V RMS in, max 400V RMS out

An application engineer that sells these products should be able to help you, otherwise please provide more details: Are you after a digital signal to indicate the spring is compressed or and analog signal to indicate the degree of compression? What is the distance from outside of the plastic...

The only parameter I can see that would influence the design is to minimise the current through the different sections of the busbar. To work this out you need to supply the power rating of the generators and loads as well as typical usage pattern of the generators and loads. Layout of design...

As it is a taper potentiometer, could it be that it has just been wired incorrectly?

The SEL RTAC is predominantly aimed at electrical power distribution applications.
