3.1.3 Setting of Integrated Low-cut Power
[Procedure]
(1) Write an integrated low-cut power value to the two D registers in the table below. The
data type is 4-byte floating point.
(2) After writing that value, write 1 to the setup change status register, D0207.

Description
Integrated low-cut power
(float, lower 2 bytes)
Integrated low-cut power
(float, upper 2 bytes)
Setup change status
(D0201 to D0206 are validated)
Effective Range
0.05 to 20.00
Unit: %
If other than 1: Invalid
If 1: Writing is executed
Initial value of integrated low-cut power: 0.05% (4-byte floating-point data: 3D4CCCCD)
[Example]
To set the integrated low-cut power value to 10.0%:
For station number 01, use PC link communication (without checksum) and the random
write command as shown below:
If 10.0 is converted into a 4-byte floating-point value, the value is 4120 0000.
