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.
