Servo control
5.18 Dynamic Servo Control (DSC)
Diagnostics
Parameter r1407 indicates which DSC closed-loop control structure is active, e.g. r1407.20 = 1
means "DSC with Spline on".
Requirements for the display:
● p1190 and p1191 must be connected to a signal source with a value of > 0 (DSC structure
activated).
● OFF1, OFF3 and STOP2 must not be active.
● The motor data identification must not be active.
● Master control must not be active.
The following conditions can mean that although the bit is set, the DSC function is not active:
● Isochronous mode has not been selected (r2054 ≠ 4).
● PROFIBUS is not isochronous (r2064[0] ≠ 1).
● On the control side, DSC is not active, which causes the value of KPC = 0 to be transferred
to p1191.
