D-sub connector
HEIDENHAIN interface boards for the SIMODRIVE system in the version with D-Sub connector are
available with or without metallic isolation of HEIDENHAIN PWM signals to the Siemens interface.
Interface boards without metallic isolation are identified

On the front panel, there are the LEDs NB (not ready) and
IF (pulse release).
There is no grounding screw on the front panel.
There is no transformer on the board.
These boards have the ID numbers 291070-01,
324952-01, 02, 03 and 10 without index A.
The terminal X131 of the Siemens E/R module of boards without metallic isolation must not

The HEIDENHAIN interface boards of the first generation were produced without metallic
isolation.
