LOBAL 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.

0…
38
The first parameters 0…38 are only mentioned here for completeness. They are used for the internal handling
of the TMCL-IDE and serve for loading micro step and driver tables. Normally these parameters remain
untouched.
If you want to use them for loading your specific values with your PC software please contact TRINAMIC
and ask how to do this. Otherwise you might cause damage on the motor driver!

Parameters with numbers from 64 on configure stuff like the serial address of the module RS232/RS485/USB
baud rate or the CAN bit 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.
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.
