Hello Everyone!
I am trying to figure out how to connect a 24VDC NPN Proximity Sensor to a 230VAC contactor with 24VDC coil. I need the contactor to turn ON/OFF with the sensor signal. I have followed the below wiring diagram but my attempts have been unsuccessful (The contactor does not switch...
Hello Everyone!
I have an application where I use a VFD to control a 3-Phase AC motor. The application involves a lift which is used to transfer a load from point A to B and after unloading the lift needs to return from Point B to A.
I currently am using two Normally-Open push buttons for...

I have a single-phase motor which I want to run in forward and reverse directions using a DPDT switch. The wiring diagram for both CW and CCW is shown below:
Could someone please tell me how I should do this? Any help is appreciated!
Hello Everyone!
We recently purchased a Speed-Control Single-Phase AC induction motor with the following specs:
Model : 51K40RGN-C (Oriental Motor)
Rated Power : 40W
Rated Voltage : 200V
No. Of Poles : 4
Rated Current : 0.5A
uF : 2.5
This motor consists of four wires (blue,black,yellow and...

I am looking for a way to control its speed. Can I use a dimmer switch or a fan-speed control switch to do...
hello everyone!
I want to change the direction of rotation (FORWARD and REVERSE) of a single-phase induction motor using two magnetic contactors. However I am confused as to the type of contactors I should use:
1. Should it be a NO or NC type four-pole contactor? (220V coil)

Hello Everyone!
So in one of our machines , a potentiometer is installed along with an Ammeter display. When the resistance of the potentiometer is changed, the ammeter reading also changes correspondingly. However this reading never reaches zero when the potentiometer dial is at zero! We tried...
Hello Everyone!
So we have this application that requires precise control of motor speed and torque. We were told that via the addition of an encoder , an ac drive can get speed feedback from the motor which can then be incorporated in the drive's control algorithm for closed-loop control.
Can...
Hello Everyone!
Recently we purchased an ABB-ACS550 drive and connected it to a 5.5KW motor.When we tried to increase the output frequency above 150HZ the motor speed increases correspondingly but above 105Hz , the motor slows down and stops.
When the output frequency is then decreased the...
