9. User Interface

The front panel of this converter has a tact switch, rotary switch and 3 LEDs.
Also the rear panel has an 8-bit DIP switch.

9-1. Tact SW

The tact switch functions as alarm clear button when the alarm is activated due to abnormal occurrence.
When this switch is pushed, a command to clear the alarm is sent to the converter while in alarm state 
(ALM LED ON). 
This switch does not function when converter is not alarm state.

9-2. Rotary SW

The rotary switch functions as the RS-485 address setting for this converter.

The interface address is composed of 7 bits and can be set within the range "0x00"

"0x7E" range.

Rotary switch is used to set the lowest digits (last 4 bits) and DIP SW is used to set the highest digits.
Note: The last digit address "F" is a reserved address for broadcast address and must not be used for 
setting address.

The value pointed by the arrow of the switch is recognized as the lowest digits of the interface address.
”0x00” is default value at the time of factory shipment.
The value of the rotary switch is only recognized at the startup the control circuit in the converter (interface 
MCU initialization). If the settings are changed during converter operation, the changed setting becomes valid at 
the start of the next startup the control circuit in this converter.

9-3. DIP SW

DIP Switch functions as a setting switch to designate operating mode of this converter.

DIP switch is turned ON when the lever is pressed down.

The value of the DIP Switch is only recognized at the startup the control circuit in the converter during 

interface MCU initialization. If the settings are changed during converter operation then the changed 
settings become valid at the next start up control circuit.
