Permissible measuring range of the temperature sensors
LG-Ni1000, DIN-Ni1000 – 88 °C … 165 °C
Pt1000 – 88 °C … 240 °C
For values outside the permissible measuring range, the inverter outputs Alarm A03520
"Temperature sensor fault".
Characteristics
If you change the analog input type using p0756, then the inverter automatically selects the
appropriate scaling of the analog input. The linear scaling characteristic is defined using two
points (p0757, p0758) and (p0759, p0760). Parameters p0757 … p0760 are assigned to an
analog input via their index, e.g. parameters p0757[0] … p0760[0] belong to analog input 0.

Parameter Description
p0757 x coordinate of the 1st characteristic point [p0756 defines the unit]
p0758 y coordinate of the 1st characteristic point [% of p200x]
p200x are the parameters of the reference variables, e.g. p2000 is the reference speed
p0759 x coordinate of the 2nd point characteristic point [p0756 defines the unit]
p0760 y coordinate of the 2nd characteristic point [% of p200x]
p0761 Wire breakage monitoring response threshold
