Does it with and without LNB, motor logic does it not the receiver.
But the shop argues that with their test setup the returning to zero doesn't happen, even when the 'move'button is kept being pressed, if I understood this whole topic right?
So what makes you conclude it is (only) the motor logic that does this?
Then the shop would have seen this symptom too...

The motor logic keeps the motor going when it starts returning to 0, no idea if the receiver makes a difference triggering it, unless the receiver has limits too in its software somewhere. So many variables.

I'll try a test when I get 5, I'll connect it up with a F type T splitter, inject 12/18v in, set it to go east and let it hit its limit, then switch off the receiver/satfinder and see if it carries on going back to 0.

Maybe of interest: The eutelsat document for motor commands of diseqc 1.2; if not all of you know that already:
https://www.eutelsat.com/files/contributed/satellites/pdf/Diseqc/associated docs/positioner_appli_notice.pdf

Note the last paragraph of section 3.5: ¨In all the above circumstances, if the East (Soft) Limit has been Set and Enabled, then the motor should stop driving if it reaches the stored limit point before completing the defined task.¨
(Does this also apply to the East (Hard) Limit? Not explicitely. But it sets a standard for the expected motor behaviour under diseqc 1.2 command, I would say.)

However, the why of the weird motor behaviour still is unclear.
@RustySpoons : I'm very curious as to what will happen if you disconnect receiver connection before reaching the limit switch (with the external power)....

greetz,

Interesting document that, I'll have a good read of it. Just looked at the limit section so far.

Testing I have done so far is, hit hard limit, motor starts to head back to 0 or previous position, removed coax from satfinder, plugged it back in and motor continues going back and will not accept commands till it arrives back to that point , so I can assume a byte is set in the motor that remains in non volatile memory so when powered back up it carries on. I will test this with a power supply.

One thing that is for certain, setting soft limits to 65 stops this issue being present.

What happened with this after TJ, did you put it back up or send it back?

As I refused to deal with Hisat because I consider him not to have the necessary know how and an appalling arrogant attitude and told Stab my views but have no response from Stab.

Neither Hisat or Stab will or are unable to answer, If the rotor is meant to go back to 0 when it reaches the East limit why does it not do the same on the West limit?

Hisat states the limits should be set in the receiver software and the limits in the rotor are it appears a safety backup.

Stab states "If not really necessary, please maintain the limits in the pre-programmed positions at ± 65°.

Stab told me the motor was about 9 years old and at that time they updated them. It would appear I have an old version of the HH100 but Hisat never stated this. Hisat claims tinned food is often old but still edible. I wonder if he uses the same logic when buying a new car.

The rotor finally stopped. Hisat wanted me to send the rotor back to him, despite having paid postage 2 ways to resolve this I had to pay again. I refused and posted it to someone who has great experience in satellite installations and components. It had a burnt out component on the circuit board which could not have been caused by an external fault.

I sent the report to Stab but they ignored it. I am not going to spend more money posting the rotor to Hisat or Stab because they will without a doubt blame me for the fault. and at 75 I do not need the stress.

But all is not lost. The attitude of Stab and Hisat in particular has done them no favours, it has already cost them some lost business and more when people realise they could be buying rotors that have been superseded by a later model, which should be better or they would not have changed it. Because you pay more does not mean it is better as I have discovered with Stab. Why bother with Stab rotors with its obvious to me faults when other makes work as well if not better with no quirky settings, like reversing on East but not West and a better price.

It is easy to lose faith but I have found some companies go beyond good customer service. I recently purchased some kitchenware from Ottoni Fabbrica an Italian company, amazing customer service. What a difference in attitude compared to Stab and Hisat.

Well, good action, fine result! (of a repaired motor).
Can you tell us what component was broken, and doing what exactly in the circuit? For further reference.

It's a pity that this led to such opposed positions.
I'm with you, that I often don't readily accept a half answer, but want to know exactly why something happens, or why something would or wouldn't be 'right', questioning assumptions and (premature) conclusions.
It's called 'a spirit of inquiry' by some. Not always practical in daily use....

Blown resistor on the main circuit board , R20, near J 2 connector. Stab are not interested and do not reply when I ask them if they approve of their old stock being sold at the same price of a newer version. If I had know it was around 10 years old I would have bought another make.

Italian companies are like that, I bought a power supply from a company called C.E.P. Italia, had a nightmare getting a refund and this thing was over £300!

Not all are the same. As I mentioned previously, got a kettle from italy she wanted to match the kitchen. expensive but nice. One of the led's in the base one side was a bit dim, made no difference to me but I mentioned it to them in just in case. Personal letter 3 days later. Exchange with all postage paid. full refund inc postage or partial refund. I kept the kettle with no refunds. Customer service is worth a great deal.

I totally agree its a big thing with me if I get good service they get more business.

I always had exceptional service when dealing with Gibertini directly.

Likewise my plastic Lnb holder split on the flexible hinge so I emailed Gibertini & they sent me a cast aluminum Lnb holder from Italy the following week with no charge :)

When I buy another dish it will be from Gibertini.

I love everything about mine, I think it looks nice for a dish too.

This is amazing.
I have a blown R20 in my STAB HH100 now, too! :confused

But with me, the motor didn't move at all, anymore.
And I hope nothing else is broken. The R20 is just before a voltage regulator, I noticed....

Greetz,
A33

R20 is 39.2 Ohm, I see in the "Dossier Technique"; see page 29/30 of the attached file.
Edit: File too large to attach!

Likely it's used as a current limiter, I should imagine it's just burnt out eventually. Nothing to lose replacing it. Check the regulator hasn't gone short.

Thanks, RustySpoons. I will check that.

Also the collector pin of transistor Q2 seems to have been hot (it's a bit blackened). Could that part of the circuit have something to do with the burning of R20, too?

Photos of my circuit board with burnt R20 can be seen at the dutch forum: STAB HH100 onderdeeltje doorgebrand
Also the "dossier technique" of the HH100, complete with circuit diagram, is there: It's not too large to be uploaded to sat4all.com!


And another forum member has reported a motor with a defective R20 there. Is the R20 not dimensioned well in these motors? Should it have a greater resistance value, or be able to handle (dissipate) more power?

R20 open circuit means the motor will not turn, though while it is charring the motherboard it will cause all sorts of trouble with moving east/west.

Anyone running a Stab rotor loves the smell of napalm - sorry, burning glass fibe, epoxy resin and copper foil in the morning.
