I found the "H3y-2" model suggested and can easily get it in my region.
I will buy and post the result. Maybe I have doubts in the connection of the wires, but I ask for help  :laugh:

Sounds good! But before you spend your money, make sure the the timer adjusts long enough for the  computer to boot past the serial port flashing. This timer has a 60 second maximum time delay.
It sure wouldnt hurt if you time the boot up first, just to be sure.
Here are a couple of drawings showing how to hook up that timer. Note that Im denoting a 12 volt dc timer.
First drawing is probably the simplest. It waits until the time delay is finished before applying the positive current to the drive.
Second drawing cuts the power between the drive and the motor as PL1 suggested.
In this drawing, im breaking both lines to the motor. You can just as well break only one line, which would be simpler to wire.
Good luck and keep us informed!

Hi gentlemen

I assembled another prototype for the project, now more organized, but many adjustments still needed. The idea is to take the whole mechanism and adapt it behind the arcade cabinet, plug and play type. >: D

At that first moment I used the relay connected to the windshield motor
In tests carried out with the limit switches installed, the rotation speed of the motor is high thus causing problems with the motor stopping.
"DaOld Man, PL1" thanks for the help in wiring the wires in the time relay.

I would be very happy to be able to test the version of Mroate4 with the "PWM" setting. DaOld Man  :cheers:

MRotate4 with PWM speed control

RSTIMER


Let me know if you have any problems with either of these.

Good video!
If that drive can do dynamic braking, you might try enabling it in mrotate4. It will make the motor stop faster, but the drive has to be able to do it.
Caution! If drive can not do dynamic braking it could fry the drive. Consult drive documentation, unless you are willing to take the risk.
Dynamic braking sets both directions on for a set time when the travel limit is made. Times can be set in Mrotate4.

Dynamic braking can be enabled and time to apply it can be set in Options. I would start with a very low time first. (100 MS is the minimum.)

According to this link, that drive can handle dynamic braking (fast stop).
But since I cant say for sure, use at your own risk.

Hi,

Further tests with Mrotate PWM, the pulse value between "0-30" I found very good, but the engine suffered to rotate a monitor.
There was a considerable loss of torque.
I will look for another engine with a lower RPM for further testing.
Dynamic braking was also tested and no burning scent so far.
