The Siemens 6SE7090-0XX84-0AH2 is a T300 Technology Board for the SIMOVERT MASTERDRIVES drive platform. It is a plug-in option board that adds supplementary process-specific functions—such as tension control, winder control, angular synchronism, positioning, and hoisting gear functions—to the drive's core control capabilities.
This board is the direct successor to the 6SE7090-0XX84-0AH0 (T300). According to Siemens Industry Support, the AH2 is a hardware revision of the same T300 platform, with no programming differences between the two versions. The only practical migration note is that the MS300 module must be transplanted from the old board to the new one.

Q1: What is the Siemens 6SE7090-0XX84-0AH2?
It is a T300 Technology Board for the SIMOVERT MASTERDRIVES platform. It adds process-specific functions such as tension control, winder control, angular synchronism, and positioning to the drive system .
Q2: What is the difference between AH2 and AH0?
The AH2 is a hardware revision of the AH0 T300 board. Siemens Industry Support confirms it is a direct successor with no programming differences. The only practical difference is the hardware version itself .
Q3: What must be done when replacing an AH0 with an AH2?
The MS300 module must be transplanted from the old AH0 board to the new AH2 board. This preserves the technology function software and ensures identical application behavior .
Q4: Is this product still in production?
No. It is a legacy SIMOVERT MASTERDRIVES component, discontinued and available only through the industrial aftermarket (refurbished units or remaining stock) .
Q5: What is the function of the T300 board?
The T300 board implements supplementary process-specific functions such as tension control, winder/reel control, angular synchronism, positioning, and hoisting gear functions. These execute on the board's processor, offloading them from the main drive control .
Q6: What is the net weight and country of origin?
Net weight is approximately 1.6 kg. Country of origin is Germany .
Q7: What is the MS300 module?
The MS300 is the software module (EPROM) that contains the technology function program for the T300 board. It must be moved from the old board to the replacement board during exchange .
Q8: What should I verify before ordering?
Always verify the exact part number (6SE7090-0XX84-0AH2), confirm your host drive is a SIMOVERT MASTERDRIVES unit, check the condition and warranty of the specific unit offered, and ensure you have the MS300 module from your original board available for transplant .
