This is exactly what i want to do. What did you understand i want to do?martyscncgarage wrote: ↑Sun May 29, 2022 4:39 pm The 120 turret works well, Emco engineered it, we have a schematic, why change it?
The turret is designed to roll forward slightly past the tool position and the roll back against the pawl.
As i said, i am german and maybe there are some communications problems with my wording^^
But (also Emco did that in original) the current of the turret-motor should be reduced after contacting the pawl to around 20% (PWM, 40kHz, 60%/40%)
And i found the datasheet for the Maxon-Motor, it says 700mA for continuous use. So 20% would be around 140mA.
Yes, I want to use the relais-solution from the schematics, but i also want to reduce the current after contacting the pawl/in "holding-state" to not overheat the motor. This motors are no longer available, afaik.
So a current-sensor in the reverse-direction-path that switches to a reduced-current after sensing the blocking-current should be the easiest way?
