9.3.3.4 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.
9.3.4 Active faults menu (M4)
The
Active faults menu
can be entered from the
Main menu
by pushing the
Menu button right
when
the location indication M4 is visible on the first line of the keypad display.
When a fault brings the frequency converter to a stop, the location indication F1, the fault code, a
short description of the fault and the fault type symbol (see Chapter 9.3.4.1) will appear on the
display. In addition, the indication FAULT or ALARM (see Figure 42 or Chapter 9.1.1) is displayed
and, in case of a FAULT, 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
.
Find the fault codes in Chapter 11.2, Table 37.
The memory of active faults can store the 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
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 or fieldbus.
NOTE! Remove external Start signal before resetting the fault to prevent unintentional restart of
the drive.
NOTE! There are some special functions that can be performed when in the
M3
menu:
Select the keypad as the active control place by keeping the START button pushed down for 3 sec-
onds 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 keeping the STOP button pushed down for 3 sec-
onds 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 keeping the
button pushed down for 3 seconds.
Note that if you are in any other than
M3
menu these functions will not work.
If you are in some other than
M3
menu 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
