Advanced commissioning
6.2 Inverter control
In addition, you must also set the switch associated with the analog input. You can find the
switch on the Control Unit behind the front doors.
• The DIP switch for AI0 and AI1 (current / voltage) on the Control Unit behind
the lower front door.
• The DIP switch for AI2 (temperature / current) on the Control Unit behind the
upper front door.
Permissible measuring range of the temperature sensors
LG-Ni1000, DIN-Ni1000
Pt1000
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.

Examples for scaling characteristics
Description
x coordinate of the 1st Characteristic point [V or mA]
y coordinate of the 1st Characteristic point [% of p200x]
p200x are the parameters of reference variables, e.g. p2000 is the reference speed
x coordinate of the 2nd Characteristic point [V or mA]
y coordinate of the 2nd Characteristic point [% of p200x]
