When "100" is set in Pr.52 Operation panel main monitor selection, set frequency is monitored during a stop and output frequency is
monitored during running.

When position control is selected, the number of pulses is monitored when Pr.430 ≠ "9999".

Displayed increments differ according to the combination of Pr.37, Pr.144, and Pr.811. For the details, refer to the Instruction Manual (Detailed)
of the inverter.

Write data is in hexadecimal, and only two digits are valid. (The upper two digits are ignored.)

Differs according to capacities.

Setting from remote registers (RWw0) can be made.

Turning OFF the power supply while clearing parameters with H5A5A or H55AA sets back the communication parameter settings back to the
initial values.

Reading or writing is available when the link parameter extended setting = "1 or 9".

Gain frequencies can be written using Pr. 125 (instruction code H99) and Pr. 126 (instruction code H9A) also.
NOTE
• When the 32-bit parameter setting or monitor description are read and the read value exceeds HFFFF, the reply data will be
HFFFF.
 Monitor codes
Information about the inverter can be monitored by setting the special monitor selection No. of the instruction code and
monitor code using the remote registers, RWw26 to 2F.
NOTE
• The monitor codes (monitor items) are the same as those of the RS-485 communication dedicated monitor.
For the details of the monitor code and monitor description, refer to the section of the monitor display in the Instruction
Manual (Detailed) of the inverter.
• 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.

All parameters return to the initial values.
Whether communication parameters are also cleared or not depends on the data.
(: Cleared, : Not cleared)
Refer to the Instruction Manual (Detailed) of the inverter for Parameter clear, All

Parameter clear
All parameter clear
When clear is executed with H9696 or H9966, communication parameters also return
to the initial values. When resuming operation, set the parameters again.
Executing clear will clear the instruction code HEC, HF3, and HFF settings.
HFD H9696: Resets the inverter.
Read or write of bias and gain parameters (instruction codes H5E to H61 and HDE to
