DETAILS OF INPUT AND OUTPUT SIGNALS
Set the monitor code to be monitored. By setting "1" in RYC after setting, the specified monitored
data is stored in RWr4 to 7.
Set how many fault records in past to be read. Back to eight fault records in past can be read. (lower
8 bits is H00)
Upper 8 bits: H00 (latest fault) to H07 (eight faults in past)
When H08 to HFF is set to the lower 8 bits, the fault record becomes an undetermined value.
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%"
When performing torque control under Real sensorless vector control or vector control with Pr.544
CC-Link extended setting = "14, 18" and Pr.804 Torque command source selection = "3, 5",
specify a torque command value. The value is written to the inverter either by RYD or RYE. Pr.805
Torque command value (RAM) and Pr.806 Torque command value (RAM,EEPROM) are also
updated at the same time. The setting range and setting increments depend on the Pr.804 setting.
Set the instruction code (Refer to
error reference, error clear, etc. The instructions are executed in the following order by setting "1" in
RYF after completing the register setting: RWw2, 10, 12, 14, 16, then 18. After completing the
execution up to RWw18, "1" is set in RXF. Set HFFFF to disable an instruction by RWw10 to 18.
(RWw2 is always executed.)
The first 8bits are link parameter extended setting.
Example) When reading Pr.160, instruction code is H0200.
Description
• 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.
