4.2.3.3 Motor temperature detection, terminals T1, T2
The KEB COMBIVERT P6 has a switchable KTY84/PTC evaluation. The input has „basic
insulation“ to the supply respectively to the „protective separation voltage“ ! The desired func -
tion is set with dr33 and works according to the following table:

Info
KTY or PTC cable inside the motor cable only permissible with double
shielding !
Info
Do not lay KTY or PTC cable of the motor (even shielded) together
with control cable !

KTY sensors are poled semiconductors and must
be operated in forward direction! Connect anode
to T1 ! Non-observance leads incorrect measure -
ment in the upper temperature range. Protection
of the motor winding is no longer guaranteed.
