| Function Name | Description | Indication |
|
| Appears when a communication error between the PU and inverter occurred, the |
|
| PU disconnection | communication interval exceeded the permissible time during the |
|
| communication with the PU connecter, or communication errors exceeded the |
| |
|
|
| |
|
| number of retries during the |
|
| Retry count excess | Appears when the operation was not restarted within the set number of retries. |
|
| Parameter storage devide | Appears when operation of the element where parameters stored became |
|
| alarm | abnormal. (main circuit board) |
|
| CPU error | Appears during the CPU and peripheral circuit errors. | / |
| / | ||
|
|
|
|
*5 | Operation panel power | Appears when the |
|
failures | supply short circuit |
| |
| was shorted. |
| |
| supply short circuit |
|
|
Major | 24VDC power output short | Appears when terminals |
|
circuit |

|
|
| |
| Output current detection | Appears when output current exceeded the output current detection level set by the |
|
| value exceeded | parameter. |
|
| Inrush resistor overheat | Appears when the resistor of the inrush current limit circuit overheated. |
|
| Communication error | Appears when a communication error occurred during the |
|
| (inverter) | with the |
|
| Analog input error | Appears when 30mA or more is input or a voltage (7.5V or more) is input with the |
|
| terminal 2/4 set to current input. |
| |
|
|
| |
| Internal circuit error | Appears when an internal circuit error occurred. |
|
| Brake transistor alarm | This function stops the inverter output if an alarm occurs in the brake circuit, e.g. |
|
| damaged brake transistors. In this case, the inverter must be powered off |
| |
| detection |
| |
| immediately. (Internal circuit error for the model 55K or less) |
| |
|
|
|
*1 Resetting the inverter initializes the internal thermal integrated data of the electronic thermal relay function.
*2 The error message shows an operational error. The inverter output is not shut off.
*3 Warnings are messages given before major failures occur. The inverter output is not shut off.
*4 Minor faults warn the operator of failures with output signals. The inverter output is not shut off.
*5 When major failures occur, the protective functions are activated to shut off the inverter output and output the alarms. *6 The external thermal operates only when the OH signal is set in Pr. 178 to Pr. 189 (input terminal function selection).
