### 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
|
||||
```
