1. Torque limitation, speed limit controller (G160)
2. Current limitation (G161)
3. Auto-reversing stage, armature gating unit (G163)
4. Closed-loop field current control, field gating unit (G166)
At this sheets you will see all required parameters. Or look at the chaptrer 11 (Parameter list) and here 11.9 to 11.14.

If you want to use drive for small motor, look at chapter 7.5 and point "Adjustment of converter rated currents", where it is described how to reduce rated armature and field currents of converter using parameter P076.
