Re: motor question- G-11 hit tripod

John,
There are several protections built into the Gemini system.
If the motor gets stuck (or worm gear jams, or scope is trapped by a wall or a snagged cable), the Gemini is designed to detect this high current and report a "Lags" or "Stalled" motor.??
The L6295PD motor dual "H bridge" chip has also a current sensor and limit of 2.8 amps. It will shut down if it tries to drive a higher current.??
Since your system went back to Park ok, All the parts are likely just fine.??
All the best, Michael
Responding to this old post as a similar thing happened to me last night.
?
I have a G11G with a SLW on the RA assembly.? I was trialing N.I.N.A. indoors just to check connection to my mount, guider, focuser and camera, and had forgotten to switch off the Gemini 2 after I was done.? This morning I found the telescope leaning against a bookshelf.? I quickly switched off the Gemini-2 and felt the RA motor.? It was just slightly warm to the touch.? I hadn't read the last message on the Gemini 2 before switching it off.? I switched the Gemini 2 on again and tried slewing east/west and the motor seemed fine.
?
Does anyone know if this would have damaged the RA motor in any way, or any gear in the RA assembly?? My son said he heard a "clicking" sound every few seconds.? Would this have been a gear slipping, or the Gemini 2 resetting itself?
?
The owner from the original post said his RA motor was red hot, but otherwise fine.? Mine was just slightly warm.? I'm wondering whether the SLW would have handled this better, or whether the Gemini 2 some logic to stop the motor if the current exceeds a certain level.
Thank you and regards,
John
