Pulse Width Modulation (PWM) Control for Digital Pneumatic Valves and CylindersLearn how to distinguish solenoid current PWM from mechanical valve PWM, verify switching limits, map duty cycle to flow, and commission a pneumatic cylinder circuit.
The Physics of Solenoid Actuation: Force, Stroke, and Response TimeLearn how solenoid force changes with stroke, why a 12 ms valve rating needs test conditions, and how current, load, and air gaps set real response time.
The Impact of Voltage Tolerance on Solenoid Valve PerformanceSMC permits -15% to +10% voltage on one valve series, while other coils specify ±10%. Learn to verify hot, loaded coil voltage before commissioning approval.
