FR-A800 5 - 813
Parameters Ethernet communication (FR-A800-E)
The display can be changed to rotations per minute according to the Pr. 37, Pr. 144, and Pr. 811
settings. ( (Refer to page 5-341).
When Pr. 541 "Frequency command sign selection" = "1", the setting value has or -. When
the setting value is negative, the command is the inverse from the command.
Setting range: -327.68 Hz to 327.67 Hz (-327.68 to 327.67) 0.01 Hz increments. (Refer to page 5-804.)
When Pr.128 = "50, 51, 60, 61", they are valid.
If the data outside the range is set, the previous setting is retained. (Refer to page 5-543.)

Torque limit level
(1st quadrant to 4th quadrant)?
When Pr. 544 = "24 or 28" and Pr. 810 = "2" during speed control or position control
(Real sensorless vector control / vector control / PM sensorless vector control), torque
limit values can be specified for each of the 1st to the 4th quadrants.
(Setting range: 0 to 40000 (0 to 400%), setting increment: 0.01%)
The value is written to the inverter by RYD. (EEPROM write by RYE is disabled.)
When "HFFFF" is set in RWwD to RWwF, the RWwC setting is applied to the operation
in the target quadrant.
When a value within the setting range of Pr. 805 or Pr. 806 is entered in RWwC while
Pr. 804 = "3 or 5", the Pr. 805/Pr. 806 setting is updated. If the data outside the range is
set, the previous setting is retained.

Link parameter extended setting/
Instruction code
Set an instruction code (refer to page 5-816) for an operation such as operation mode
switching, parameter read/write, 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.)
Set the link parameter extended setting in the upper eight bits.
Example:
When reading Pr.160, instruction code is H0200.

Write data
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, 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.
