Servo-Control
The servo-loop gain multipliers (1.125 and 0.875) are defined by the system.
A following error gives two theoretical speeds, V1 and V2. The real axis speed must be between these two values
for correct operation of the position servo-loop.
If the real speed is outside the theoretical speed band, the system generates one of errors 40 to 71.
REMARKS: For correct use of the settings of this parameter, the position servo-loop time
constants must be specified in parameter P56 (see 6.7).
The value of zero in a word disables dynamic control on the corresponding
axis.
UNI-TE request (see UNI-TE Protocol User’s Manual)
Dynamic movement control can be modified by a UNI-TE request. A reset (CNC reset) resets the CNC to the state
specified by P57.
