For the FR-F800 series, no function is assigned in the initial setting.
The signal is valid only for the FR-A800 series.
Torque control cannot be performed with a PM motor.
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.
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).
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.
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
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.
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).
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
