MTR_TEMP 10   Input of motor temperature sensor
Shell — Connect the cable shielding layer Shielded

This port is used for connection between drive and motor encoder. During use, distance between the cable and main circuit wire should be 30cm;

  • Please use shielded twisted pair cable for encoders;
  • Input of fully closed-loop encoder is differential input, and its Max. input frequency and Min. pulse width are shown in the table below:
Pulse method Max. frequency (pps) Min. pulse width (μs)
Differential input 4M 0.125


CN7 Input of motor temperature sensor

Support PT/NTC/switch types of motor temperature sensors. Please ensure that function codes P00.05/P08.31/P08.33/P08.34 are set properly.
