●
Input signals (inverter to master module)
Device No. Signal Description
RX0 Forward running
0 : Other than forward running (during stop or reverse rotation)
1 : Forward running
RX1 Reverse running
0 : Other than reverse running (during stop or forward rotation)
1 : Reverse running
RX2 Running (terminal RUN function)
앫
Functions assigned to terminals RUN, SU, OL, IPF, FU, ABC1 and ABC2 activate.
앫
Signal names are initial values. Using Pr. 190 to Pr. 196, you can change output
signal functions.
RX3 Up to frequency (terminal SU function)
RX4 Overload alarm (terminal OL function)
RX5
Instantaneous power failure (terminal
IPF function)
RX6
Frequency detection (terminal FU
function)
RX7 Fault (terminal ABC1 function)
RX8 — (terminal ABC2 function)
RX9 — (DO0 function)
앫
Functions assigned to Pr. 313 to Pr. 315 are activated.
앫
No signal is assigned in the initial setting. Use Pr.313 to Pr.315 to assign signals to
the devices RX9 to RXB. The setting range depends on the inverter. For details,
refer to the description of Pr. 190 to Pr. 196 (Output terminal function selection)
on page 5-378.
RXA — (DO1 function)
RXB — (DO2 function)
RXC Monitoring
After "1" is set in the monitor command (RYC), and the monitored value is set in the
remote register Rwr0, 1, 4 to 7,, "1" is set in this signal. When "0" is set in the monitor
command (RYC), "0" is set in this signal.
RXD
Frequency setting completion / torque
command setting completion (RAM)
After "1" is set in the frequency setting command/torque command (RYD) and the
frequency setting command/torque command is written to the inverter RAM, "1" is
set in this signal.
When "0" is set in the frequency setting command /torque command (RYD), "0" is set
in this signal.
RXE
Frequency setting completion /
torque command setting completion
(RAM, EEPROM)
After "1" is set in the frequency setting command/torque command (RYE) and the set
frequency is written to the inverter RAM and EEPROM, "1" is set in this signal.
When "0" is set in the frequency setting command/torque command (RYE), "0" is set in
this signal.
RXF Instruction code execution completion
After "1" is set in the instruction code execution request (RYF) and the processes
corresponding to the instruction codes (RWw2, 10, 12, 14, 16, and 18) are executed,
"1" is set in this signal. When "0" is set in the instruction code execution request (RYF),
"0" is set in this signal.
RX1A Error status flag When an inverter error occurs (protective function is activated), "1" is set in this signal.
RX1B Remote station ready
When the inverter goes into the ready status upon completion of initial setting after
power-ON or hardware reset, "1" is set in this signal. When an inverter error occurs
(protective function is activated), "0" is set in this signal. The signal is used as an
interlock signal during the write to/read from the master module.
