5 Global Parameters
GLOBAL PARAMETERS ARE GROUPED INTO 4 BANKS:
- bank 0 (global configuration of the module)
- bank 1 (user C variables)
- bank 2 (user TMCL variables)
- bank 3 (interrupt configuration)
Please use SGP and GGP commands to write and read global parameters.
5.1 Bank 0
Parameters with numbers from 64 on configure stuff like the serial address of the module and the RS485
baud rate. Change these parameters to meet your needs. The best and easiest way to do this is to use the
appropriate functions of the TMCL-IDE. The parameters with numbers between 64 and 128 are stored in
EEPROM only.
Attention:
- An SGP command on such a parameter will always store it permanently and no extra STGP command
is needed.
- Take care when changing these parameters, and use the appropriate functions of the TMCL-IDE to do
it in an interactive way!

E
STGP, RSGP
Parameter automatically restored from EEPROM after reset or power-on. These
parameters can be stored permanently in EEPROM using STGP command and
also explicitly restored (copied back from EEPROM into RAM) using RSGP.

EEPROM magic
Setting this parameter to a different value as
$E4 will cause re-initialization of the axis and
global parameters (to factory defaults) after
the next power up. This is useful in case of
miss-configuration.
