## FAQ
### Axis hardware error at startup
If at IOC startup you are met with the following errors:
```
2026/02/02 16:56:49.470 Controller "turboPmac1", axis 3 => asynStatus turboPmacAxis::handleError(int, char*, int), line 735
Driver hardware error triggered.
2026/02/02 16:56:49.485 Controller "turboPmac1", axis 7 => asynStatus turboPmacAxis::handleError(int, char*, int), line 735
Driver hardware error triggered.
2026/02/02 16:56:49.492 Controller "turboPmac1", axis 8 => asynStatus turboPmacAxis::handleError(int, char*, int), line 735
Driver hardware error triggered.
```
You may need to reset to do a axis reset. This can be done with writeRead python tool. The following example does so for axis 3.
Confirm the hardware error:
```
utils/writeRead.py 172.28.87.24:1025 P0301
# If it returns 13 it's a hardware error.
```
Reset the axis:
```
utils/writeRead.py 172.28.87.24:1025 P0301=0
```
