CONTROL KEYPAD

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.
