Details of remote register

The following device numbers are those for station 1.
For stations 2 and later, the device numbers are different. (Refer to the master module manual for cor-

Description
Specify the set frequency or rotations per minute (machine speed). At this time,
whether to write to RAM or EEPROM is decided with the RY21 and RY22 settings.
After setting the set frequency in this register, set "1" in RY21 or RY22 to write the
frequency. After writing of frequency is completed, "1" is set in RX21 or RX22 in
response to the input command.
The setting range is 0 to 590.00 Hz (0.01 Hz increments). Write "59000" when
setting 590.00 Hz.
Specify the torque command value / torque limit value. Set Pr. 804 "Torque command
source selection" = "1, 3, 5, or 6" to activate this signal under Real sensorless vector
control, vector control, and PM sensorless vector control. The value is written to the
inverter either by RY23 or RY24. Pr. 805 "Torque command value (RAM)" and Pr. 806
"Torque command value (RAM, EEPROM)" are updated as well. The setting range and
setting increments depend on the Pr.804 setting. (Refer to page 5-759).
Set the PID set point.
Setting range: "0 to 100.00%"
Set the PID measured value.
Setting range: "0 to 100.00%"
Set the PID deviation.
Setting range: "-100.00% to 100.00%"
Set an instruction code (refer to page 5-757) for an operation such as operation mode
switching, parameter read/write, alarm reference, and alarm clear in the lower eight
bits. The instructions are executed in the following order by setting "1" in RY25 after
completing the register setting: RWw10, 12, 14, 16, 18, then 1A. After completing the
execution up to RWw1A, "1" is set in RX25. Set HFFFF to disable an instruction by
RWw10 to 1A. Set the link parameter extended setting in the upper eight bits.
Example:
When reading Pr.160, instruction code is H0200.
Set the data specified by the instruction code of RWw10, 12, 14, 16, 18 and 1A. (when
required) RWw10 and 11, 12 and 13, 14 and 15, 16 and 17, 18 and 19, and 1A and 1B
correspond each other.
Set "1" in RY25 after setting the instruction codes (RWw10, 12, 14, 16, 18 and 1A) and
the corresponding register. Set "0" when the write code is not required.
Set the number of previous faults you want to be able to read in the faults history.
Up to 8 previous faults can be read.
Last two digits: H00 (most recent fault) to H07 (8th most recent fault).
Set H08 to HFF to make the faults history No. to "0."
Set the monitor code to be monitored. By setting "1" in RY20 after setting, the
specified monitored data is stored in RWr26 to RWr2F.
If a monitor code out of the setting range is set, no item is monitored (the monitor
value is fixed to 0).
The monitor codes are the same as those of the RS-485 communication dedicated
monitor. (Refer to page 5-344.)
When the remote registers RWw26 to 2F are used for monitoring, H01 (output
frequency) and H05 (set frequency) always indicate the frequency regardless of the
settings of Pr. 37, Pr. 144, and Pr. 811.
inverter)
Parameters
Input a value 100 times greater than
the value to be set.
For example, input "10000" when
setting 100.00%.

control.
