== Overview ==

Chinese servo drives by JMC (Just Motion Control, aka Shenzhen Just Motion Control Electromechanics 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 [[JMC JASM Series Servo Motors|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.

To be able to write certain groups of parameters, you must "unlock" them either from the servo drive keypad using <code>AF_unL</code>, or by changing parameter <code>P10-22</code>, 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 <code>jmc</code> and the "Super authority" password is <code>jmc2018</code>, which allow you to access the <code>P10-xx</code> parameters.
