Frequently Asked Questions
1. Is the A5E00430139 compatible with the Micromaster 420 series?
No, this power board is specifically designed for the Micromaster 440 series and supports the higher power ranges of that specific line.
2. What should I do if my drive displays a "Power Stage Fault" after installation?
You should verify all ribbon cable connections and ensure that the IGBT modules are functioning correctly, as this board interacts directly with them.
3. Why is this part listed as a "Discontinued" item?
Siemens has moved toward the SINAMICS line, but they continue to support the MM440 series through these specialized spare part catalogs.
4. Does this board handle the communication protocols like PROFIBUS?
This board handles power delivery and gate driving; however, the communication is managed by the separate control head attached to the front of the drive.
