Temperature encoder KTY 83-110 (integrated temperature detector)
The motor temperature is monitored continuously using
the KTY temperature detector, although this does not offer
full protection.
The feedback to the servo inverter 9300 is carried out using
the feedback system cable. When the encoder is fed with a
measuring current of 1 mA, the relationship between tem-
perature and resistance will be as follows:
Temperature sensor KTY83-110
Resistance in Ω
Temperature in °C
Thermostat – NC contact (TKÖ)
As an alternative to the continuous sensor KTY, a tempera-
ture contact can also be used to monitor the windings of
motor series SDSGA.
