Digital Keypad Functions and
Indications
Description of the functions of the keys and
indicators of the GS20X AC Drive Keypad.
Descriptions of Keypad Functions
RUN Key
• Valid only when the source of operation command is from the keypad.
• RUN can be pressed even when drive is in process of stopping.
• When in “LOCAL” mode, RUN is valid only when the source of operation command is from
the keypad.
STOP/RESET Key
This key has the highest processing priority in any situation.
• When the drive receives a STOP command, whether or not the drive is in operation or stop
status, the drive will execute a "STOP" command.
• The RESET key can be used to reset the drive after a fault occurs. For those faults that can't
be reset by the RESET key, see the fault records after pressing MENU key for details.
N OTE: The ability to STOP the drive from the keypad is effective ONLY if the drive is configured
to RUN and/or STOP from the keypad. Keypad STOP can be disabled by parameter 00.32,
Digital Keypad STOP Function.
ENTER Key
Press ENTER to go to the next menu level or accept parameter entry. If it is the last level, then
press ENTER to execute the command.
MENU Key
Press MENU to return to the Main Menu or cycle through the available menu options.
Direction: Up
Press to make the value set on the current menu/parameter higher.
Direction: Left/Down
• Press to make the value set on the current menu/parameter lower.
• In the menu/text selection mode, the arrows are used for item selection. Long press the
MENU key to use the left direction function.
Descriptions of LED Functions

Steady OFF
: Drive is not currently executing an operational (STOP) command.
N OTE: The ability to STOP the drive from the keypad is effective ONLY if the drive is configured to
RUN and/or STOP from the keypad. Keypad STOP can be disabled by parameter 00.32, Digital
Keypad STOP Function.
