• Function

: Disconnection detection of remote keypad

Added the operation selection when the extended panel option (RKP002Z (LED), RKP004Z (LCD)) cable is broken. If you want to stop the inverter when the disconnection detected, set ￿￿￿￿=0.

￿￿￿￿: Override addition input selection

￿￿￿￿: Override multiplication input selection

• Function

These parameters are used to adjust reference frequencies by means of external input.

The override functions calculate output frequency by the following expression:

	Value [%] selected with ￿￿￿￿
Frequency command value × (1+		)+Value [Hz] selected with ￿￿￿￿
	100

1)Additive override

In th1is mode, an externally input override frequency is added to operation frequency command.
