PLC Motor Control VFD Setup: DOL, PowerFlex 525, G120
Choose DOL or a drive, wire the stop so it works without the PLC, set the drive parameters and tags, then read the fault codes when it trips.
Electrical basics
Motors, VFDs, contactors, wiring and panel layout: the electrical side a controls engineer has to get right before any code runs.
PLC I/O Modules: Sinking, Sourcing, Keying, Scaling
How to pick discrete and analog I/O, get sinking and sourcing right, set RPI and electronic keying, wire a 4-20 mA loop and scale the raw counts.
Counting Runtime Hours and Trending Vibration in the PLC
Build PLC predictive maintenance on hardware you own: vibration and motor current inputs, runtime hours, moving averages, baselines and alarm levels.
Generator Start Permissives, Sync Handover and Load Shed
Where the PLC stops and the relay starts, a generator start permissive rung, the synchronising handshake, load shed stages and switchgear interlocks.
RSLogix PLC Programming Motor Start/Stop program
Motor Start/Stop One Button Example We will examine how to start and stop an engine with a single button. Of course, while doing this, we plan to do this with minimum staff. In order to be suitable for the electrical circuit, instead of Latch and Unlatch (Set – Reset) commands the contacts that sealed it … Read more
Siemens PLC Drive Motor Start Stop
Siemens PLC Programming Drive Motor Regarding the previous article (Siemens Tia Portal). [irp posts=”3465″ name=”Siemens TIA (Totally Integrated Automation) Portal”] Let’s take an example and show step by step. In order to drive a DC Motor 30 seconds by a button (START and STOP), the following ladder diagram can be used. We choose the first … Read more
Electric Motors
What is the engine? Engine Types Motor: Machines that convert any energy into mechanical energy are called engines. Machines that convert heat energy into mechanical energy are called heat engines. Automobile engine is a heat engine. Motor that convert electrical energy into mechanical energy are called electric motors. The engine of the washing machine, the … Read more
Star-Delta Motor Starting Mathematical Expansion
Motor Starting Ways Asynchronous motors draw up to 3-4 times their nominal current at the time of the first start. Although these values do not have much effect on the electrical installation in small motors, they can cause some negative situations in large powerful motors. When a large powerful asynchronous motor draws 3-4 times the … Read more
Motor Start/Stop via Timer
When the start button is pressed, the engine will start immediately and stop after 10 seconds. It will run again 10 seconds after it stops. (Two time relays will be used.)
What is Encoder? Usage Areas and Types
The encoder is an electromechanical device that generates a digital (digital) pulse signal that generates signals in response to the motion of the motor shaft to which it is connected. It is also a sensing device that monitors the current positions of the connected shaft and provides feedback. The encoder sends a feedback signal that … Read more
