CMSX-...-C-U-F1-...
Lower and upper limit of the setpoint value signal range (SPMIN, SPMAX)
The parameters SPMIN and SPMAX establish the lower and upper limit of the signal range for the ana­
logue setpoint value specification – independent of the character of the setpoint characteristic curve.
Exceeding these limits has no influence on the setpoint value specification. The following figure shows
as an example the influence of the parameters on the linear setpoint value characteristic curve with the
setting SPMIN 20 % and SPMAX 80 % (DIRECT = increase).

Fig. 30 Influence of the parameters SPMIN, SPMAX on the signal range of the setpoint value
specification – example
With a preset signal direction (DIRECT = increase), the lower limit value of the signal range is assigned
to the lowest setpoint position and the upper limit value to the highest setpoint position.
