Split from Basic knowledge of Drive and Motor control.

hello, if I've got you right,

here are two screenshots of same window where realized control torque via potentiometer. it works well.

sir 

In my Drilling machine  I need to vary speed but torque should be constant so which mode should I have to select?

also suggest me Drive for 1 phase 0.5 HP, 0.37 kW, 3.5 A ratting motor  which I will use in Drilling machine.

In which mode use in this programme?

I mean torque  or speed control?

 If you need just drill machine equipped with "Start/Stop" buttons and "Speed" potentiometer.

I think there is not necessity to use Sinamcs VFD,which offers more far capability you need.Of course more capability means that more money you should pay. So I think you have to pay attention to younger brother of Sinamics, it's MICROMASTER.

As example look at this variant:  6SE64402UC155AA1

 Using Starter you can select Configuration -> Wizard - Speed Control (encoderless) for motor settings.

To youre selected anologue input you need to configure following as shown below.

it's left and right parts of same window where configured speed control via  potentiometer connected to youre selected analogue input.

the potentiometer, which you can connect to analogue input, may look like that.

Please do not recommend MICROMASTER 4 as a younger brother of SINAMICS.

MICROMASTER 4 is soon to be phased out.

Also, if I read it correctly and the motor is a single phase motor please see:

And get a 3 ph motor
