7.3.3.2 Keypad reference
The keypad reference submenu (P3.2) displays and allows the operator to edit the frequency reference.
The changes will take place immediately. This reference value will not, however, influence the rotation
speed of the motor unless the keypad has been selected as source of reference.
NOTE: The maximum difference in RUN mode between the output frequency and the keypad reference is 6
Hz.
See Figure 7-5 for how to edit the reference value (pressing the
Enter button is not, however, necessary).
7.3.3.3 Keypad direction
The keypad direction submenu displays and allows the operator to change the rotating direction of the
motor. This setting will not, however, influence the rotation direction of the motor unless the keypad
has been selected as the active control place.
See Figure 7-6 for how to change the rotation direction.
7.3.3.4 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.
Note: Additional Information on controlling the motor with the keypad is given in Chapters 7.2.1 and
8.2
NOTE! There are some special functions that can be performed when in menu M3 :
Select the keypad as the active control place by keeping the
start
button pushed
down 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 keeping the
stop
button pushed
down 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 keeping the
enter
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.
