+### 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
+```
