6 Functional Description
The IDX module has three different modes to control a stepper motor: step-direction, RS485 and
stand alone. With the RS485 it is possible to change parameters and save them to the EEPROM of
the module to have all options in any mode. Therefore there are different settings like microstep
resolution possible in step-direction mode also.
6.1 Disable Function
Description: The disable works as an emergency shutdown. Connected to ground all power to the
motor will shut down independent of the current settings.
It is in the users responsibility to stop the step impulses or set the velocity to zero before enabling the
motor again, because it would start abrupt otherwise.
Function Table:
6.2 RS485 Control Interface
The RS485 interface can control all functions of the IDX. It is possible to change parameters, with this
interface which are also valid in the other modes like max. velocity or acceleration. The parameters
can be written to the EEPROM to obtain the changes after a restart.
A Reset to factory default is possible. Default address byte is “A” and default baud rate is 9600 baud.
This mode can only be used with an appropriate RS485 interface. Commands are sent with a terminal
program, refer 5.5.
