I have an issue regarding a motor circuit I'm working on.
I have a:
- S120, 4.9kW.- CPU 313 2DP
- Electro motor
My issue is that when I'm driving this system with a heavy load, with a profibus analog joystick in both directions, there is no problem. I can push it to the limit by driving it very fast in both directions.
But when I drive it really slow, but only down, it's dropping the load. I don't find any limitations at all on this problem, and would be very gratful for some help.
