Kollmorgen TT-2953-3038-ADC
Product Name: TT-Series Servo Motor Thermal Transmitter (PT100, 4–20 mA, ADC output)
Product Overview:
A precision stator-winding temperature probe built for Kollmorgen AKM and PMA servo motors. It converts platinum-RTD resistance into a linear 4–20 mA current loop so a drive or PLC can execute thermal derating or safe-stop without an external transmitter.

Features:
Linear current output, reverse-polarity protected, EMI-hardened for motor compartment, calibrated at factory, no user zero/span adjustment required.
Working Principle:
RTD resistance varies with stator temperature; an onboard signal conditioner drives a 4–20 mA transmitter; 4 mA = low-end (−50 °C), 20 mA = high-end (+200 °C). Drive reads current on analog input and maps to thermal model.
Applications: AKM/PMA servo over-temperature protection, packaging-machine servo axes, CNC spindle aux motors, any cabinet-less motor thermal monitoring.
Installation & Notes:
Insert fully into designated stator hole; secure with retaining clip. Use shielded twisted pair, ground drain at drive end only. Do not exceed 24 VDC on loop. Mixing this ADC probe with a resistive-input drive thermal channel will fault the axis.
