I recently purchase two PD1-140-42-SE-CANopen stepper motor with integrated controler. I wanted to install a newest firmware on the board. With the first motor everything worked fine. After I tried the second board no connection works afterwards. The red and green led is on permanentely. I tried to get it back to the factory default:
- TMCL-IDE-program -> EEPROM locked and communication error
- connecting pins 5 to Gnd, connection pin 3 TXD and pin 2 RXD together -> no change
- connection pad 2 and pad 3 on the bottom -> no change
Thank you for help!
