Overview
Chinese servo drives by JMC (Just Motion Control, aka Shenzhen Just Motion Control Electromachics Co.,Ltd.) that support both incremental ABZ/UVW encoders as well as Tamagawa 17-bit (and maybe 23-bit?) encoders. It is meant for use with their JASM series servo motors.

The RS-232 baud rate corresponds to the setting PA00-21, even parity, 1 stop bit. The slave address seems to be set from PA00-23. It seems to only want to communicate over RS-232 and not RS-485, though maybe there is a trick to it.
| Micro USB Pin | Direction | DE9 Pin (DTE) | Function |
|---|---|---|---|
| 1 (VCC) | drive → PC | +3.3V (for isolator?) | |
| 2 (D-) | drive → PC | 2 (RXD) | PC's RS-232 RX in |
| 3 (D+) | drive ← PC | 3 (TXD) | PC's RS-232 TX out |
| 4 (ID) | |||
| 5 (VCC) | drive ↔ PC | 5 (GND) | GND (digital common) |
To be able to write certain groups of parameters, you must "unlock" them either from the servo drive keypad using AF_unL, or by changing parameter P10-22, which cannot be navigated to by the keypad. You must instead do it over RS-485 or RS-232 via the PC software. The software has an unlock dialog that requires the passwords: the "Primary authority" password is jmc and the "Super authority" password is jmc2018, which allow you to access the P10-xx parameters.
