7.2.1
Remote register (master module to inverter (FR-A8NCE))
Remote register definition
Device No.
Signal
Description
RWw0
Set frequency
• 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.
Torque command
value
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
.)
Torque limit value
RWw4
PID set point
Set the PID set point
Setting range: "0 to 100.00%"
• Input a value 100 times greater than the value to
be set.
For example, input "10000" when setting 100.00%.
• Refer to the Instruction Manual (Detailed) of the
inverter for details of PID control.
RWw5
PID measured value
Set the PID measured value
Setting range: "0 to 100.00%"
RWw6
PID deviation
Set the PID deviation.
Setting range: "-100.00% to 100.00%"

Instruction code
Set an instruction code (refer to
) 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.
