Version with ribbon
cable connector
HEIDENHAIN interface boards for the SIMODRIVE system in the version with ribbon cable feature
metallic isolation of the HEIDENHAIN PWM signals to the Siemens interface.
Thus, the terminal X131 must be available at the SIEMENS drive system!
The individual expansion boards must also be connected to the central signal ground of the machine
via the grounding screw on the front panel.
