IDS are ABB Inverter specialists. We specify, install, commission, repair, service and hire variable speed drives.
In this video, George Dodwell from ABB demonstrates PID Control. Using our demo rig, which comprises of an inverter, a fan, a damper and a pressure control point. The pressure is fairly crucial to this demonstration. George explains that PID Control is the principle of using an inverter to control the speed of an application. An example would be, if you stay overnight in a hotel, take a shower in the morning at the same…
In this video, ABB’s Area Sales Manager, Stuart Ruskin demonstrates PID control using our demo rig. The demo rig consists of an inverter, a motor, a fan and a damper. In this demonstration the damper will be used to control the flow in this instance air, but the demonstration is just as applicable to water. PID Control Demo The 1st setting on the inverter, Stuart sets the desired pressure. The 2nd setting is the current…
In this video, Inverter Drive Systems Ltd Account Manager, Simona York, demonstrates PID Control using an Inverter. In the demonstration, Simona uses a demonstration rig, our Balloon Machine, which consists of an ABB inverter, a motor, a fan with damper (which can be used to control the flow) and a pressure sensor. On the keypad of the inverter, the first reading is the set point, 70 Pascals in this case. The second reading is the…
Two PID (proportional integral derivative) controllers, feature in the latest ABB drives, making it easier and less expensive to set up control loops to manage industrial processes. The ABB drive contains two independent PID loops, which can be selected from digital inputs. The addition of the two loops means that instead of simply controlling the speed of the motor, the drive can command the motor to run at a speed that will allow the user…
As in the previous comments on using inverters on centrifugal pumps and fans in AHU’s and water systems to save energy, then to give better and even more accurate control on energy savings using inverters, then using P.I.D control (proportional integral derivative) in everyday language sensors, fitted along with the inverter, will give better control. PID Control Sensors on Inverter Drives Again to give an example using the driving of a car as an analogy,…
