Signal names are initial values. Using Pr.180 to Pr.189, you can change input signal functions. Note that some of signals do not accept a
command from the network according to the Pr.338 and Pr.339 settings. For example, the RES signal (the function assigned to terminal RES) in
RYB cannot be controlled via network. Refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter for details of Pr.180 to
Pr.189, Pr.338, and Pr.339.

For the FR-F800-E, no function is assigned in the initial setting.

The signals are fixed. They cannot be changed using parameters.

While "1" is set in the frequency setting command (RYD), the set frequency (RWw1) is always applied.

If "1" is set in these registers at the same time while Pr.544 = "0," only one of these is executed.

The torque command / torque limit setting is available only for the FR-A800-E.

Torque control cannot be performed with a PM motor.

When "1" is set in RYC, the monitored value is set in the remote register RWr0, 1, 4 to
7, and "1" is set in the monitoring (RXC). While "1" is set in RYC, the monitored data is
always updated.
When "1" is set in RYD, the set frequency/torque command (RWw1) is written to RAM
of the inverter.
After the writing completes, "1" is set in the frequency setting / torque command
completion (RXD).
(RAM) Under Real sensorless vector control, vector control, and PM sensorless vector

control, the following value is also written to RAM at the same time.
• During torque control
• During speed control / position control: Torque limit value
When "1" is set in RYE, the set frequency/torque command (RWw1) is written to RAM
and EEPROM of the inverter. After the writing completes, "1" is set in the frequency
setting / torque command completion (RXE).
Under Real sensorless vector control, vector control, and PM sensorless vector

control, the following value is also written to RAM and EEPROM at the same time.
• During torque control
• During speed control / position control: Torque limit value (Pr.544 ≠ "24 or 28")
To change the frequency consecutively, be sure to write data to the inverter RAM.
When "1" is set in RYF, processes corresponding to the instruction codes set to
RWw2, 10, 12, 14, 16 and 18 are executed. "1" is set in the instruction code execution
request (RXF) after completion of instruction codes. When an instruction code
execution error occurs, a value other than "0" is set in the reply code (RWr2, 10, 12,
14, 16, 18).
When "1" is set in RY1A at an inverter fault, the inverter is reset, then "0" is set in the
error status flag (RX1A).
for operation conditions of inverter reset.
Description
When "1" is set, a start command is input to the inverter.
When "1" is set in RY0 and RY1, a stop command is input.
