Defective Simodrive amplifier
Issue:
Press doesn't start after longer stand still powered off. Starting the press in production is not possible and errors listed below show on the HMI. The machine can start after a while or several power off/on. Other issues can be a loss of the X-axis reference and/or Y-axis can't be referenced. The Simodrive control card shows an error.
Possible errors on HMI:
- Axis X1: not referenced
- Axis Y1: not referenced
- Axis Y2: not referenced
- NE-modul power supply not OK
- NE-modul not ready for operation
Remedy:
- If not referenced, reference X-axis (see related knowledge article)
- Swap the Y-axes amplifier, if Y-axes can't be referenced. If the error moves to the other drive, a new amplifier is needed.
Important:
Only swap the amplifier and not the controller card. The controller card has dedicated parameters loaded.
Miscellaneous:
The NE-modul (E/R-module) goes into an error state if one of the drives has an error on the display. Keep in mind, the above listed error also can point to a defective NE-modul.
