2.10 KEYPAD CONTROL PARAMETERS

3.1 Control

place

The active control place can be changed with this parameter. For more information,
see Vacon NXL User's Manual, Chapter 7.4.3.

3.2

Keypad frequency reference

The frequency reference can be adjusted from the keypad with this parameter. For
more information, see Vacon NXL User's Manual, Chapter 7.4.3.2.

3.3 Keypad

direction

Forward: The rotation of the motor is forward, when the keypad is the active

control place.

Reverse: The rotation of the motor is reversed, when the keypad is the active

control place.

For more information, see Vacon NXL User's Manual, Chapter 7.4.3.3.

3.4

Stop button activated

If you wish to make the Stop button a "hotspot" which always stops the drive regardless
of the selected control place, give this parameter the value 1 (default). See Vacon NXL
User's Manual, Chapter 7.4.3.
