- motor encoders, rotary/direct measuring systems, linear
- motor encoders, linear/direct measuring system, rotary:
The parameters p2503 (LU per 10 mm) and p2506 (LU per load revolution) are also effective.
<3> The function module "Advanced Position Control (APC, r0108.7)" is only available for SINUMERIK controllers with integrated SINAMICS functions.
