5.2.7 Option: Motor Temperature Sensor Connection X3/X4
The temperature evaluation module is used for monitoring the stepper motor temperature.
Depending on the selected evaluation module (KTS01 or PTS01) thermal elements type K
or platinum sensors PT100 can be used.
The insulated temperature sensor in phytron motors is integrated in the motor windings.
The response time is very short, compared to temperature sensors mounted outside the
motor housing. The temperature is measured all the time, even if only one motor phase is
powered at any one time.
Thermal element type K
With the Type K (NiCr-Ni) in-vacuum and cryo stepper motors, thermal elements in the
temperature range from
–270 to +1370 °C, accuracy class 1, are used.
The Type K is a metal thermal element with nickel-based alloy conductors. Temperature
ranges, accuracy and characteristics of thermal elements for industrial use are defined in
the IEC 584 standard (temperature measuring with thermal elements).
