STOP Button Activated

By default, pushing the STOP button will always stop the motor regardless of the selected control place. You can disable this function by giving parameter 3.4 the value 0. If the value of this parameter is 0, the STOP button will stop the motor only when the keypad has been selected as the active control place.

Note: There are some special functions that can be performed in menu M3:

Select the keypad as the active control place by pressing start for 3 seconds when the motor is running. The keypad will become the active control place and the current frequency reference and direction will be copied to the keypad.

Select the keypad as the active control place by pressing stop for 3 seconds when the motor is stopped. The keypad will become the active control place and the current frequency reference and direction will be copied to the keypad.

Copy the frequency reference set elsewhere (I/O, fieldbus) to the panel by pressing enter for 3 seconds.

Note: If you are in any other menu than menu M3, these functions will not work.

If you are in some other menu than menu M3 and try to start the motor by pressing the START button when the keypad is not selected as the active control place, you will get an error message: Keypad Control NOT ACTIVE.

Active Faults Menu (M4)

You can enter the Active Faults menu from the Main menu by pressing Menu Button Right when the location indication M4 is visible on the first line of the keypad display.

When a fault brings the drive to a stop, the location indication F1, the fault code, a short description of the fault, and the fault type symbol (see below) will appear on the display. In addition, the indication FAULT or ALARM (see Table 5-1) is displayed and, in case of a FAULT, the red LED on the keypad starts to flash. If several faults occur simultaneously, the list of active faults can be browsed with the Browser buttons.

The memory of active faults can store a maximum of 10 faults in the order of appearance. The display can be cleared with the RESET button and the read-out will return to the same state it was in before the fault trip. The fault remains active until it is cleared with the RESET button or with a reset signal from the I/O terminal.

Note: Remove external Start signal before resetting the fault to prevent unintentional restart of the drive.
