What is alarm text of alarm 8?

We were able to get 6SN1145-1ba01-0ba1 and 6sn1145-1ba1-0ba2 16/21kw in China, these are more modern simodrive611 power supply numbers, being 0ba2 2014 for a very nice price of US$1300, in my country it costs US$3000, the question is can I use them without any problems? A technician in my country says 1ba01 uses more modern components. Will they be more resistant or more fragile? Would it be worth buying a 35/47kw 6SN1145-1ca01 in China for the price in my country of US$3000?

Could someone comment on my questions and doubts with supposed attempts to correct the problems. Thanks

To the colleagues who followed this post, here are the updates. The ALARM8 "axis not synchronized" in 810M was due to the axis input board in 810m being defective. I got one for testing and then we bought a used one.

The simodrive 16/21kw power supply was burnt out, we used a borrowed one to make progress on the problems.

After the power supply was replaced, a Y axis drive showed ERROR 7, and it had to be sent to the service center for repair. After all these problems were solved, we have a semi-operational machine, where the axis movements are working. Now we can reference the axis home.

Thinking that everything would be wonderful after months of struggle, we bought a 36/47kw power supply because we had reports from the technical support that the first machines with 16/21 had serious problems with the power supply burning out, and in the following years we were already using 36/47. The power supply was purchased and installed, and an unknown problem arose. The power supply's filter inductor began to make loud noises and overheat, even without activating the axis movement, only in ready-to-operate mode. We then needed to buy an inductor compatible with a 36/47kW power supply, and we ended up importing the inductor and the power filter module from Denmark to Brazil, since the price was lower than in Brazil itself.

Everything was ready once again, and now we tried to activate the spindle and nothing happened. We detected that the spindle drive also showed a no current error, which made us buy another used drive without even trying to fix this one.

drive changed, we lost the configuration of the 611U controller, downloaded the SIMOCOM-U software, did new programming and managed to get the spindle to run controlled by the PC, but now we can't run it by the CNC, when doing the M3S1000 command in MDI the command executes the same but we don't have the analog output of the 810M entering the 611U board to control the spindle speed.

We have already done a test with a 9Vdc battery box on pins 56 and 14 and we have spindle rotation. We are thinking that there is some restriction in the PLC, some input not activated that is not allowing the 810m to send the +-10v to control the spindle rotation, like an open door sensor for example. Having more news we will update the post again.
