    400V & 110V in same Junction Box?

    Just a terminal block separator if your using different colour terminal block, or different colour connection strips. Or use an earth terminal block to separate them.

    Electrical Cabinet for Industrial use.

    Afternoon, is there any requirement for electrical cabinets to be all metal? Or is any flame retardant ok? It’s for a basic PLC cabinet with inputs / outputs to a Cobot. Very light industrial, nothing ever gets damaged etc.

    What is happening with Automation?

    Evening, There seems to be a high demand for Automation / Controls Engineers at the moment. Larger companies seem to be starting new automation departments in their companies. What do we think will happen, is it to help reduce the labour problems of the last year or so? Is it to ramp up...

    Looking for a VFD with good scaling for display.

    That’s a way, I was hoping to find a reason to use a different drive this time though! Looking at the Siemens V20 it has a multiplier and divisor but it’s so hideous to look at! Thanks.

    Looking for a VFD with good scaling for display.

    Evening, I currently use Rexroth VFD´s, but the scaling options are a bit sparse. Basically it has a multiplier that you can set from 0.1 to 100. For example on a pillar drill I added one to, I wanted the display to show RPM, but as the motor is geared down (for example 12:1), you only get...

    As a Maintenance Engineer were should i go from here ?

    Electrical fault finding is way harder (in my opinion) than mechanical stuff. I´m Engineering Manager at a factory, I´ve just seen your only 20, so yes go on some courses if you think you can do it, can you tag along with the electrical people at your factory? The opinion I have always heard is...

    Servo Drive burning out encoder input.

    Hi, both machines work the same but have obviously been wired up by different people. It was several months ago that this problem last appeared. As far as I can remember the actual wiring connections were the same, as was the earthing, but I will check when I get a minute. The encoder goes to a...

    Servo Drive burning out encoder input.

    Thanks for the replies. To answer questions: The PSU is A din rail mounted Meanwell. I forgot to mention we have an identical machine that doesn’t suffer the same problem. We have no working oscilloscope. I tried to record voltage when the e-stop is pressed on a Fluke 289 data logging...

    Servo Drive burning out encoder input.

    Evening, we have a machine (being deliberately vague) it has a main motor, which is driven by a VFD, on the spindle of the shaft driven by the motor is a rotary incremental encoder, something like 1000 pulse / revolution. This encoder controls a Servo Drive which drives a small motor for another...

    Why I feel electric shock when I pressing a 24V control button?

    We used to have an operator who was always getting electric shocks from the machines. I told her to stop wearing wool jumpers!

    How to get into Controls / Automation / PLC´s.

    Evening! I´m looking into getting more into the Controls / PLC / Automation side of things. I´ve programmed a few PLC´s (Siemens) from scratch and a HMI. Some knowledge of Servo Drives (fault finding, setting basic parameters), programming VSD´s, designing / construction of control panels etc...

    Street light removal, any tips?

    They also need to be a certain distance apart as it is a way of determining a speed limit :)

    How Old Was You When You Became Interested In Electrics?

    I think it was this book when I was 9 or 10. One of the first things I built was an electric motor from this book. I may (or may not) teach it to my local Cub group, but fear they are too young. My first electric shock that I remember was when I was on the CB radio, I had a 12v PSU which had...

    UK Regs .?

    At a previous company we had a 400A printing machine (2x PC´s, 5x Allen Bradley PLC´s, 55 motors mostly servo´s mainly Bosch Indramat, electrical cabinet was a shipping container on stilts - if anyone`s interested), it was wired in singles on cable tray across the factory, the cables went into...

    DOL starter switch Trips out

    Some very good advice on here. I often swop the phases round twice at the DOL so that I can see if a fault is incoming or on a motor. One thing I want to add is removing the motor connection bars completely and checking the bolts underneath are tight, I´ve found them loose on old and brand new...
