Got the RL01 up and running.
Home sensor with contact problems and poorly adjusted.
- Follow constant "pulling" of the posit. towards the home position.
- Follow high current of Pos. damage DC Servo Board
- Consequence of heat generation
- Defective power transistor on the DC servo board
and depending on the vibration, the home switch worked or not. - Stupid hardware error!
But the fact that I had a spare DC servo board and a spare home microswitch here solved the problem.
(I have good spare parts here from 4 RL drives with broken motor or rust and similar damage)
Spare parts storage is important with now 3 x RL01 and 6 x RL02 - but they all work at the moment and I still have 9 air filters original packed and sealed from DEC.
