Note
Additional temperature monitoring circuit Temp‑S
1FW6090-xxxxx-xxx2 to 1FW6290-xxxxx-xxx2 motors are equipped with an additional
temperature monitoring circuit Temp‑S. The associated interface designations are 2TP1 and
2TP2.
Note
Checking the shutdown circuit
Before commissioning and before switching on the DC link voltage for the 󹪝rst time, carefully
check the Temp‑S temperature monitoring circuit to ensure that it correctly shuts down (trips).
The typical characteristic R(ϑ) of a PTC temperature sensor according to DIN 44081 is provided
in the Chapter "Technical features of temperature sensors (Page54)".
