S-analogue output
With parameter No. 84 the minimum voltage for S-analogue ouput can be programmed. This minimum voltage
is the permissible minimum value which will not damage the spindle drive.

Parameter No. 70 permits the programming of the oscillating vclltage output during gear change.
Ramp gradient for S-analogue 168
0 - 1.999 Volts/ms
With parameter 168 the ascending flank for S-analogue voltage output can be programmed if a voltage jump is
not required.

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.
