Drive unit reset Write HFD
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.

H9966: resets the drive unit
When data is sent normally, ACK is returned to the computer and then the
drive unit is reset.

Parameter clear
All clear
Write HFC
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.
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 (refer to page 145), only H9966 and
H55AA (all parameter clear) are valid.
∗1 Turning OFF the power supply while clearing parameters with H5A5A or H55AA
also clears the communication parameter settings back to the initial values.

Read H00 to H63
Refer to the instruction code (Refer to page 52) and write and/or read
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

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).

Setting calibration parameter (For calibration parameters, refer to the list of
calibration parameters on the next page.)
H00: Speed (The gain speed can also be written using Pr. 125 (instruction
code: H99) or Pr. 126 (instruction code: H9A))
