4.3.1 DIP-switch settings
The controller iMC-S8 has four stepper motor power amplifiers MD28. Settings for
rated current, step resolution and current reduction takes place by the DIP-switch on
the top side of the amplifiers case.
Configuration of the controller should be done before first start-up
so that a connected motor will not be damaged because of an
incorrect power setting.
To configure the step resolution and motor current open the cover and set the jumper
on each amplifier as follows (more information /1/ Microstepping Driver MD24/MD28):
