ERROR: The name of the drive that the inverter is driving - In error (-XX.X)
ERROR: The name of the drive that the inverter is driving - In error (-XX.X)
This error can occur on any inverters, for example; fan, elevator, rollers, turbines. We open the electrical cabinet and find the inverter in error, the label from the error text must match the label on the label. A faulty inverter usually also has one red light on, which indicates an error.
Danffoss:
- We place keyboard to this invertor, usually only one inverter has a keyboard, which can be moved.
- Read the active alarm code from the screen and check it in the manufacturer's instructions..

| 67 | Option change | - | x | - | A new option is detected or a mounted option is removed. |
| 68 | Safe Torque off | x | x | - | STO is activated. If STO is in manual restart mode (default), to resume normal operation, apply 24 V DC to terminals 37 and 38, and initiate a reset signal (via fieldbus, digital I/0, or [Reset] / [Off Reset] key). If STO is in automatic restart mode, applying 24 V DC to terminals 37 and 38 automatically resumes the frequency converter to normal operation. |
