Signal
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.
