8010 – 04 Motor Coil Resistance (AS1050 28 [0.28Ohm]) 32 28 36 36 36
8010 – 06 Motor FullSteps – always 200 for Beckhoff Steppers 200 200 200 200 200
8010 – 07 Encoder Increments – always 4096 for Beckhoff Steppers 4096 4096 4096 4096 4096
8012 - 05 Speed range is max speed in motor steps, calculated from pitch, max speed etc.

Needs to tie up with Ref velocity in NC Parameters – see below

4000


[1200rpm]

2000 1000 1000 1000
8012 - 08 Feedback type

Encoder feedback is best as it closes the loop. For open loop, use Internal, but this can loose steps / position
