Limitation of S-Override 0.. . 15OC%I
maximum 88
minimurn 89
With these parameters, the limitation for the S-Override potentiometer is prograrnmed (No. 88 maximum,
No. 89 minimum). After reaching the programmed limitation - either max. or min., the S-Analogue
voltage remains constant.
Minimurn voltage for
S-Analogue output
184 0 . . . 9.999 rv1
With parameter No. 84 the minimum voltage for S-Analogue output can be programmed. This minimum
voltage is the permissible minimum value which will not damage the spindle drive.
Please note:
This limitation is ineffective with an activated spindle orientation option.

Depending on the machine, MP 190 can be programmed to define whether in addition to the minimum
output voltage determined with MP 184, the voltage "0" may be output or not in the lowest gear stage.
