Thanks for your feedback. Currently I dont have the servo motor in hand so I cannot show that. But the home functions shown in the TIA Portal TO is quite clear, it is diagram style. You can figure out much easier than Beckhoff.
The servo drive homing is a hard topic. If a TH-cam channel is an organization or a company, homing how-how is their competence, in comparison, if a TH-cam channel is a personal channel, it is really really hard to present this because it needs real servo and mechanical system, need many times to setup the equipement and explain the concepts behind but the view of the videos would be just hundreds per year. Therefore, finding a qualified video that thoroughly explained this homing topic would be rare. What I'd like to say is that, read the manual carefully and practice in your applications. Find the correlated homing scenarios matching your case (fix stop home, cam sensor homing, z-mark home, direct home, etc.) . Note that handling this knowledge is not easy and is free to get. However, manual documents and deep research studies are effective solutions.
If we use the "Z mark" directly as Home sensor. How should we do the setting up. Because for my drive is Z mark know as "touch probe" in PDO mapping and it has typ UINT, so i cant connect it to bCalibrationCam? Can you help me please?
Hi Bud, using a sensor and the homing sequence to 'Home' the axis is to keep the 'HOME' consistent. means that the 'HOME' position recorded in the axis always this position. Regarding the accuracy, the best method is to use the 'Z' mark of the encoder. It can cover 99% high accuracy applications.
Never seen a application only use zero pulse only. The common case is use a home sensor to find a "almost close position" at first, then use zero pulse to finally/accurately set a position value. Because this zero pulse will be ON at every rotation of the encoder, use it only doest not work. unless your encoder only spin within one rotation.

Excellent instructions. Clear and concise. Very helpful.
Glad it was helpful! Welcome!
Thank you very much! Nice explanation!
Glad it was helpful!
Thanks!
Thanks very much!
A great explanation for the homing method! Would you mind to make one episode as this regarding the homing mode for mc_home in siemens? Thank you.

tq sir....
Thanks! Welcome!
Sir for simatic manager how to do the incremental encoder homing program
And how to reset the encoder value please help me

Regarding the 'Z mark', TwinCAT NC named it as "Hardware Sync Pulse", it can be found from Axis - > Encoder -> Reference Mode -> Hardware Sync
Great 👍 but how accurate it will be for most of the applications? What is the maximum possible error for homing in incremental encoder?

@@electricalautomation thank you for the reply.
Hi! Have you done before without the reference cam (Home sensor) and only with the zero pulse on the encoder?
Never seen a application only use zero pulse only. The common case is use a home sensor to find a "almost close position" at first, then use zero pulse to finally/accurately set a position value. Because this zero pulse will be ON at every rotation of the encoder, use it only doest not work. unless your encoder only spin within one rotation.
