*1 When Pr.541 Frequency command sign selection = 1, the setting value has either + or -. When the setting value is negative, the
command is inversed from starting command.
Set how many fault records in past to be read. Back to ten fault records in past can be read (lower
8 bits is H00).
Upper 8 bits: H00 (latest fault) to H09 (ten faults in past)
When H0A to HFF is set to the upper 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
*2
Setting range: "0 to 100.00%"
Set the PID deviation.
Setting range: "-100.00% to 100.00%"
When Pr.544 = "14 or 18" and Pr.804 = "3 or 5" during torque control (Real sensorless vector
control), torque command values can be specified. The value is written to the inverter by RYD or
RYE. Pr.805 and Pr.806 are also updated at the same time. The setting range and the setting
increment depend on the Pr.804 setting. If the data outside the range is set, the previous setting is
retained.
When Pr.544 = "14, 18", Pr.804 = "3 or 5", and Pr.810 Torque limit input method selection = "2"
during speed control (Real sensorless vector control / PM sensorless vector control), torque limit
values are specified. The value is written to the inverter by RYD or RYE. Pr.805 and Pr.806 are
also updated at the same time. The setting range and the setting increment depend on the Pr.804
setting (absolute value). If the data outside the range is set, the previous setting is retained.
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 8 bits are link parameter extended setting.
Example) When reading Pr.160, instruction code is H0200.
Set the data specified by the instruction code of RWw10, 12, 14, 16, and 18. (when required)
RWw10 and 11, 12 and 13, 14 and 15, 16 and 17, and 18 and 19 correspond each other.
Set "1" in RYF after setting the instruction codes (RWw10, 12, 14, 16, and 18) and the
corresponding register.
Set "0" when the write code is not required.
Description
• Input a value 100 times greater than the value to be set
For example, input "10000" when setting 100.00%.
• For the details of PID control, refer to the FR-E800
Instruction Manual (Function).
