4. Functions in detail

Remote Keypad can be used as remote operation panel (“REMOTE KEYPAD MODE”) or parameter

back-up device (“COPY MODE”). When the “COPY MODE” led is lit when turning power on, Remote

Keypad operates in “COPY MODE”, otherwise in “REMOTE KEYPAD MODE”.

4.1. Procedure to switch the operation mode

According to the procedure described in “3. Connection and start-up”, turn on the power of Remote

Keypad while holding down the [ENT] key of Remote Keypad. Operation mode changes.

4.2. “REMOTE KEYPAD MODE”

In “REMOTE KEYPAD MODE”, operation is the same as operation on the panel of the inverter. For

details, see instruction manual of the inverter. Data entered through Remote Keypad takes priority

over data entered through the inverter’s control panel. However, if Remote Keypad is deactivated by

an unexpected event such as an abnormality, the inverter’s input keys remain functional.

4.3. “COPY MODE”

In “COPY MODE”, storing and loading the parameters are permitted. Editing the parameters is not

permitted.
