Description
When "1" is set in the error reset request flag (RY3A) at an inverter fault, the inverter is
reset, then "0" is set in the error status flag (RX3A). Refer topage 5-633 for operation
conditions of inverter reset.
Description
0 : Other than forward running (during stop or reverse rotation)
1 : Forward running
0 : Other than reverse running (during stop or forward rotation)
1 : Reverse running
Functions assigned to terminals RUN, SU, OL, IPF, FU, ABC1 and ABC2 activate.
Signal names are initial values. Using Pr. 190 to Pr. 196, you can change output
signal functions.
Functions assigned to Pr. 313 to Pr. 315 are activated.
No signal is assigned in the initial setting. Use Pr.313 to Pr.315 to assign signals to
the devices RX10 to RX12.
After "1" is set in the monitor command (RY20), and the monitored value is set in the
remote register RWr26 to RWr2F, "1" is set in this signal. When "0" is set in the monitor
command (RY20), "0" is set in this signal.
After "1" is set in the frequency setting command (RY21) and the set frequency is
written to the inverter RAM, "1" is set in this signal.
When "0" is set in the frequency setting command (RY21), "0" is set in this signal.
After "1" is set in the frequency setting command (RY22) 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 (RY22), "0" is set in this signal.
After "1" is set in the torque command / torque limit (RY23) and the torque command
/ torque limit value is written to the inverter RAM, "1" is set in this signal.
When "0" is set in the torque command / torque limit (RY23), "0" is set in this signal.
After "1" is set in the torque command / torque limit (RY24) and the torque command
/ torque limit value is written to the inverter RAM and EEPROM, "1" is set in this signal.
When "0" is set in the torque command / torque limit (RY24), "0" is set in this signal.
After "1" is set in the instruction code execution request (RY25) and the processes
corresponding to the instruction codes (RWw10, 12, 14, 16, 18 and 1A) are executed,
"1" is set in this signal. When "0" is set in the instruction code execution request
(RY25), "0" is set in this signal.
When an inverter error occurs (protective function is activated), "1" is set in this signal.
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.
