Learn how to fix VFD overvoltage issues from AutomationDirect.

🤖 Sequence Program-Controlling Two Cylinders 🤖 I programmed a sequence in Siemens LOGO! Soft Comfort to control two pneumatic cylinders: ➡️ First, Cylinder 1 extends. ➡️ Once Cylinder 1 is fully extended, Cylinder 2 extends. ➡️ When Cylinder 2 is fully extended, both cylinders retract at the same time. This small project demonstrates how to build a clear sequence logic using a PLC and sensor feedback. A simple exercise – but the same principle is used in industrial automation systems all over the world.

PID Control: Balancing Precision & Stability” In automation, precision is power — but stability is wisdom. That’s where PID control comes in — the invisible hand that keeps processes smooth, stable, and efficient. Whether you’re controlling temperature, pressure, or flow, PID is the brain behind the balance. 🧩 Tune wisely. Measure often. Optimize always. #AutomationEngineer #PIDControl #PLCProgramming #ProcessControl #IndustrialAutomation #TIAportal #EngineeringLogic #AutomationDiaries #SufiRehan

Ever had a VFD throw a fault code and thought “What on earth does that mean?” From OC, OH, and GF, to UV and OL, these cryptic two-letter warnings actually tell a story about what’s happening inside your drive. This carousel decodes the most common VFD fault messages, what causes them, and how to fix them fast before downtime turns costly. At Creative Automation, we help industries keep motion systems running smoothly through smarter diagnostics, better setup, and hands-on support. 📩 For VFD troubleshooting, automation, or motion control assistance: creativeautomation.ae #VFD #Drives #FaultCodes #Automation #IndustrialEngineering #Maintenance #CreativeAutomation

𝐃𝐚𝐲 2: 𝐄𝐦𝐞𝐫𝐠𝐞𝐧𝐜𝐲 𝐒𝐭𝐨𝐩 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 Today’s work is a continuation of yesterday’s motor start-stop control, but with an important safety addition: the emergency stop. The goal was to add an emergency stop button that overrides the start/stop logic and cuts power immediately. In real-world systems, safety always comes first. Before building this, I had a chat with a professional in the field, Liam Bee, who shared something that really stuck with me. He explained that in practice, the stop push button should be programmed in the PLC as a normally open (NO) contact, while the physical relay wiring should be a normally closed (NC) contact. Why? Because this way, the PLC receives a clear, intentional signal when someone presses the button. At the same time, if the wiring is cut or power is lost, the NC circuit opens by default and the machine stops. It’s a simple design choice that makes the system much safer. I applied this new knowledge in designing today’s circuit. The result is a motor control system with start, stop, and emergency stop integration, just as you’d expect in a real industrial setup. See you tomorrow for Day 3. #PLCProgramming #IndustrialAutomation #AutomationEngineering #ControlSystems #30DaysOfPLC #AutomationChallenge #SafetySystems #MotorControl

🧩 Problem Statement The system operates automatically with Push Button ON/OFF control. When ON is pressed ▶️, Reagent 1 is pumped until Level Sensor LS2 (half level) is reached, then Reagent 2 is pumped until LS3 (full level). At LS3, the Pump and Valve 2 (V2) 🛑 stop, and the Mixer ⚙️ and Heater 🔥 start simultaneously. When the temperature reaches 68°C (TS1 activated) 🌡️, the Heater turns off, while the Mixer continues to run for 15 seconds more ⏱️. After mixing, Valve 3 (V3) 💧 opens to drain the product until LS1 is reached, then V3 closes. The cycle restarts 🔁 when Valve 1 (V1) and Pump are reactivated. ⚙️ Components V1, V2, V3: 24 V DC solenoid valves, normally open (energize to open) Heater: Controlled by thermostat TS1, normally closed at 68°C LS1, LS2, LS3: Float-type level sensors (NO) Pump: Controlled through a 9A, 4-pole contactor 💡 Solution To automate this process, a PLC-based control system was designed and implemented. ✅ The ladder logic program for this process was developed using RSLogix 500 software. ✅ The program was implemented on an Allen-Bradley MicroLogix 1400 Series A PLC. ✅ The system sequence includes pumping, level detection, heating, mixing, and draining operations, all controlled through PLC logic using input signals from sensors (LS1, LS2, LS3, TS1) and output signals to actuators (Pump, Valves, Mixer, Heater). ✅ The operation of the system was tested successfully, and its working was demonstrated and recorded in a video 🎥. #PLC #Automation #IndustrialAutomation #DeltaPLC #ControlSystems #ProgrammableLogicController #AutomationEngineer #SmartAutomation #ProcessControl #IndustrialEngineering #Robotics #ManufacturingAutomation #IndustrialTechnology #AutomationSolutions #EngineeringInnovation

Relay Latching Circuit in Action ⚡ — Simple ON/OFF Control with Memory In this video, I’ve demonstrated how to build a latching circuit using a relay. A latching circuit allows a load (like a lamp or motor) to stay ON even after the input switch is released, providing a simple way to maintain state without continuous pressing. ✅ Connection Explanation: Connect a push button in series with the relay coil and supply. Use one normally open (NO) contact of the relay to feed back to its own coil. When the button is pressed, the relay energizes → NO contact closes → coil remains energized even after button is released → lamp stays ON. To turn OFF, a separate OFF switch can be used to break the circuit. This self-holding relay setup is widely used in industrial machines, motor starters, and automation systems where maintaining a state is necessary without continuous user input. #Automation #Instrumentation #RelayLogic #ControlSystem #ElectricalEngineering #IndustrialAutomation #HandsOnLearning #LatchingRelay

📘 Day 12 of 30 – Interlocking Circuits in Ladder Logic In automation, safety and coordination matter. Interlocking ensures that two conflicting operations can’t happen together. ⚙️ Example: Motor 1 starts → Blocks Motor B/2 from starting. When Motor 1 stops → Motor 2 can start. ⚡Real-Life Use: Conveyor systems needing reversible motion (e.g., packaging lines). Hoists and cranes for up/down direction control. Rolling mills and extruders with forward/reverse operation. Motorized gates or jacks that change direction. 💡 In TIA Portal: Use M bits or output contacts as conditions in the other’s rung. ✅ Why it matters: Prevents damage from mechanical clashes. Ensures process safety and sequencing. 🎯 Tomorrow: We’ll move to Timers (TON, TOF, TP) — time-based logic in PLCs. #Day12 #PLCInterlock #SafetyLogic #TIAProject
