Setting Items List

IMPORTANT:

- If problems such as communication interruptions due to a disconnection of the signal wire or malfunction of the Display cannot be detected on the inverter side, implement a precautionary measure by using the inverter's communication retry function or communication check function. Refer to your External Device manual for details.
- Do not reset the inverter while communication is enabled. This may cause malfunction. Prior to resetting the inverter, take the Display offline.

## Connection Configuration

- 1:1 Connection

- 1:n Connection

NOTE

- Maximum number of External Devices is 31.

NOTE

- Maximum number of External Devices is 62.

## Communication Settings

Examples of communication settings of the Display and the External Device, recommended by Pro-face, are shown.

WARNING

UNINTENDED EQUIPMENT OPERATION

Read and understand the instructions in this section to ensure data is properly transferred.

## Cable Diagram

The following cable diagrams may be different from cable diagrams recommended by External Device Manufacturer.

Please be assured there is no operational problem in applying the cable diagram shown in this manual.

- The FG pin of the External Device body must be grounded according to your country's applicable standard. Refer to your External Device manual for details.

- SG and FG are connected inside the Display. When connecting the External Device to SG, design your system to avoid short-circuit loops.

- Connect an isolation unit if the communication is not stable due to noise or other factors.

## Supported Devices

Range of supported device address is shown in the table below. Please note that the actually supported range of the devices varies depending on the External Device to be used. Please check the actual range in the manual of your External Device.

WARNING

UNINTENDED EQUIPMENT OPERATION

- Do not simultaneously write to the same register from Display and External Device program.
- Do not write 16-bit word values to registers being accessed in a bitwise manner.

IMPORTANT:

- As shown in the following table, you may need to enter "9999" (meaning an invalid parameter setting or the like) depending upon the parameter types. In this case, the data written and read from the Display is as follows:

  Inverter Series | Inverter Setting | Written Data | Read Data
  --- | --- | --- | ---
  FR-S500/FR-F500J series | --- | -1 (0xFFFF) | -1 (0xFFFF)
  888 | -16 (0xFFF0) | -16 (0xFFF0)
  Series other than above | 9999 | -1 (0xFFFF) | -1 (0xFFFF)
  8888 | -16 (0xFFF0) | -16 (0xFFF0)
