Temperature detection T1, T2

Parameter In.17 displays in high byte the installed temperature input of the inverter. The
KEB COMBIVERT F5/F6 is delivered as standard with switchable PTC/KTY evaluation. The
desired function is adjusted with Pn.72 (dr33 at F6) and operates in accordance with the fol-
lowing table:

The column is valid at factory setting. The function must be programmed accordingly
1)
with parameters Pn.12, Pn.13, Pn.62 and Pn.72 for F5 in operating mode GENERAL.
2) Disconnection is depending on the adjusted temperature in Pn.62 (F6 => pn11/14).
The behaviour of the inverter in case of error/warning is defined with parameters
Pn.12 (CP.28), Pn.13 (F6 =>pn12/13).
Dependent on the application the temperature input can be used for the following functions:
Function
Motor temperature display and monitoring
Motor temperature monitoring
Temperature control for water-cooled motors
General fault sensing
1) If the temperature input is used for other functions, the motor temperature control at
water-cooled inverters can be done indirectly via the water cooling circuit of the inverter.
