cONNEcTION Of THE POWER UNIT

4.2.3.5 Motor temperature detection

NOTICE
The KEB COMBIVERT H6 is delivered with switchable KTY84/PTC evaluation. The
desired function is set with dr33 and works in the following table:
dr33 function of T1, T2
0 KTY84 (standard)
PTC
1 (in accordance with
60947-8)
Table 14: Motor temperature detection
The warning level is adjusted with pn11. The error level is adjusted with pn14.
1)
The behavior of the drive converter in error/warning case is set with parameter pn12.

KTy or PTc cable
• Do not lay KTY or PTC cable of the motor (even shielded) together
with control cable !
• KTY or PTC cable inside the motor cable only permissible with
double shielding !
• The input is base insulated.

KTY sensors are poled semiconductors and must be oper-
T1
ated in forward direction ! Connect anode to T1 ! Non-ob-
servance leads incorrect measurement in the upper
temperature range. Protection of the motor winding is no
T2
longer guaranteed.
KTY sensors may not be combined with other devices. Otherwise
wrong measurements will be the consequence.
