Signal
Description
RY20
Monitor command
When "1" is set in the monitor command (RY20), the monitored value is set in the remote register RWr26 to
RWr2F, and "1" is set in the monitoring (RX20). While "1" is set in the monitor command (RY20), the
monitored data is always updated.
RY21
Frequency setting
command (RAM)
When "1" is set in the frequency setting command (RY21), the set frequency (RWw0) is written to RAM of the
inverter. While "1" is set, the set frequency (RWw0) is always applied.
After the writing completes, "1" is set in the frequency setting completion (RX21).
RY22
Frequency setting
command
(RAM, EEPROM)
When "1" is set in the frequency setting command (RY22), the set frequency (RWw0) is written to RAM and
EEPROM of the inverter. After the writing completes, "1" is set in the frequency setting completion (RX22).
To change the frequency consecutively, be sure to write data only to the inverter RAM.
RY23
Torque command /
torque limit (RAM)
When "1" is set in the torque command / torque limit (RY23), the set torque command / torque limit (RWw2) is
written to RAM of the inverter.
After the writing completes, "1" is set in the torque command / torque limit setting completion (RX23).
The following value is written to RAM.
• During torque control
: Torque command value
• During speed control / position control: Torque limit value
RY24
Torque command /
torque limit
(RAM, EEPROM)
When "1" is set in the torque command / torque limit (RY24), the set torque command / torque limit (RWw2) is
written to RAM and EEPROM of the inverter.
After the writing completes, "1" is set in the torque command / torque limit setting completion (RX24).
The following value is written to RAM and EEPROM.
• During torque control
: Torque command value
• During speed control / position control: Torque limit value
To change the torque command or the torque limit consecutively, be sure to write data to the inverter RAM.
RY25
Instruction code
execution request
When "1" is set in the instruction code execution request (RY25), processes corresponding to the instruction
codes set to RWw10, 12, 14, 16, 18 and 1A are executed. "1" is set in the instruction code execution request
(RX25) after completion of instruction codes. When an instruction code execution error occurs, a value other
than "0" is set in the reply code (RWr10, 12, 14, 16, 18 and 1A).
RY3A
Error reset request
flag
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 to
for operation conditions of inverter reset.
