5.2 Remote Register Assignment

5.2.1 Remote registers (master unit → inverter (FR-E5NC))

 

Device No.

Signal

Description

 

 

RWW0

Monitor code

Set the monitor code to be referenced. By switching on the RYC signal after setting, the

 

 

specified monitored data is set to RWr0.

 

 

 

 

 

 

 

 

Specify the set frequency. At this time, whether it is written to RAM or E2PROM is

 

 

RWW1

Set frequency

differentiated by the RYD and RYE signals. After setting the frequency to this register, switch

 

 

on the above RYD or RYE to write the frequency. On completion of frequency write, RXD or

 

 

 

 

 

 

 

 

RXE switches on in response to the input command.

 

 

 

 

Set the instruction code for execution of operation mode rewrite, Pr. read/write, error

 

 

RWW2

Instruction code

reference, error clear, etc. (refer to page 29). The corresponding instruction is executed by

 

 

switching on RYF after completion of register setting. RXF switches on on completion of

 

 

 

 

 

 

 

 

instruction execution.

 

 

 

 

Set the data specified by the above instruction code. (When required)

 

 

RWW3

Write data

Switch RYF on after setting the above instruction code and this register.

 

 

 

 

Set zero when the write code is not required.

 

5.2.2 Remote registers (inverter (FR-E5NC) → master unit)

 

 

 

 

 

 

 

 

 

 

 

 

RWr0

Monitored value

The monitored value specified by RWW0 (monitor code) is set.

 

 

 

 

 

 

 

RWr1

Output frequency

The present output frequency is always set.

 

 

 

 

 

 

 

RWr2

Reply code

The reply code corresponding to RWW2 (instruction code) is set. 0 is set for a normal reply

 

 

and a value other than 0 is set for a data error.

 

 

 

 

 

 

RWr3

Read data

For a normal reply, the reply data to the instruction specified by the instruction code is set.
