6.5 Stepper Motor Connection Scheme
6.6 Enhanced Stall Detection Mode for Stepper Motors
Enhanced stall detection functionality is offered for E520.01 and E520.03 only.
Recommended configurations for stepper motor with stall detection are:
PDEx=1
OCC=1
CLMP[1:0]=11
SDS=100
STOPz=1
For the proper operation of the stall detection mode a defined assignment between driver channels and the sev-
eral motors has to be used. The following table lists the connection schemes:
