6.6 Temperature detection T1, T2
Parameter In.17 displays in high byte the installed temperature input of the drive con-
verter. 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 following table:

The column is valid at factory setting. The function must be programmed accordingly 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).
Thebehaviourofthe drive converterincaseoferror/warning is denedwith
parameters Pn.12 (CP.28), Pn.13 (F6 =>pn12/13).
Dependent on the application the temperature input can be used for the following func-
tions:
Function motor temperature display Mode (F5 => Pn.72; F6 => dr33)
Motor temperature display and monitoring KTY84
Motor temperature monitoring PTC
Temperature control for liquid-cooled motors

Table 26: Function motor temperature display
1) If the temperature input is used for other functions, the motor temperature control at liquid-cooled drive
converters can be done indirectly via the liquid cooling circuit of the drive converter.
ATTENTION
• Do not lay KTY or PTC cable of the motor (also shielded) together
with control cable !
• KTY or PTC cable only permissible with double shielding within the
motor cable !
