Menu "Keypad control" (M3)
In the
menu Keypad Control, you can choose the control place and edit the
frequency reference. Enter the submenu level with the
Menu button (right).
The menu point (M3) may only be processed by specially trained personnel.
Menu "Active faults" (M4)
The menu
Active faults can be entered from the Main menu by pressing the
Menu button (right) when the location indication
M4
is shown in the first line
of the display.
In case the frequency converter is stopped by a fault, the location indication
F1, the fault code, a short description of the fault and the fault type symbol
will appear on the display. In addition, the indication FAULT or ALARM is dis-
played. If a FAULT occurred, the red LED on the keypad starts to blink. If
several faults occur simultaneously, the list of active faults can be browsed
with the
Browser buttons.
The fault memory can store the maximum of 10 active 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 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!
Reset external Start signal before resetting the fault to prevent unintentional
restart of the drive.
