6.7.2 Temperature detection T1b, T2b

Parameter In.17 displays the function of the used temperature input in the first digit
of the hex value. The KEB COMBIVERT is delivered as standard with a switchable
PTC / KTY evaluation. The required function is set with Pn.72 (dr33 at F6) and operates
according to the following table:

Table 3: Temperature detection
The column is valid at factory setting. The function must be parameterized appropriate with parame-
1)
ters Pn.12, Pn.13, Pn.62 and Pn.72 for F5 in operating mode GENERAL.
2) The switch-off is dependent on the adjusted temperature in Pn.62 (F6 => Pn11 / 14).
Depending on the application, the temperature input can be used for the following func-
tions:
Function
Motor temperature display and monitoring
Motor temperature monitoring
Temperature control for liquid-cooled motors
General fault sensing
Table 4: Functions temperature input
1) If the temperature input is required for other functions, the motor temperature control can also occur
indirectly via the coolant circuit of the inverter.
