The increment is 0.001 and the data format is E2 or A2 when the following conditions are met: Pr.37 = "0.01 to 9998," Pr.144 = "2 to 10," and the
instruction code HFF = "01."
Code
H9696: resets the drive unit.
 As the drive unit is reset at start of communication by the computer, the
drive unit cannot send reply data back to the computer.
HFD
H9966: resets the drive unit.
 When data is sent normally, ACK is returned to the computer and then
the drive unit is reset.
HF4 H9696: clears the faults history as a batch.
All parameters return to the initial values.
Whether to clear communication parameters or not can be selected
according to data.
(: Clear, : Not clear)
Refer to page 52 for parameter clear, all clear, and communication
parameters.
Clear Type
Parameter clear
HFC
All parameter clear
When clear is executed for H9696 or H9966, communication-related
parameter settings 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. In the password locked status, only H9966 and H55AA (all
parameter clear) are valid.

Turning OFF the power supply while clearing parameters with H5A5A or H55AA
also clears the communication parameter settings back to the initial settings.
parameter values as required.
When setting Pr.100 and later, link parameter extended setting must be set.
Data format of Pr.37 read and write is E2 and A2
H7F
Parameter description is changed according to the H00 to H09 setting.
For details of the settings, refer to the parameter instruction code (Refer to
page 52).
HFF
Setting calibration parameter (Refer to the list of calibration parameters on
H6C
the next page for calibration parameters.)
H00: Speed (The gain speed can also be written using Pr.125 (instruction
code: H99) or Pr.126 (instruction code: H9A).)
HEC
H01: Parameter-set analog value
H02: Analog value input from terminal
Available for writing 2 commands, and monitoring 2 items for reading data
HF0
(Refer to page 221 for detail)
Reading drive unit type in ASCII code.
"H20" (blank code) is set for blank area
