Line speed command input by parameter setting (Pr.361 = "8")
• The value set in Pr.360 Line speed command value is used for the line speed command. (Setting range: 0 to 6553.4 m/
min)
Line speed command input through RS-485/Ethernet or using a
communication option (except for the FR-A8ND)
• Use the read/write procedure for the set frequency to read/write the line speed command value through RS-485 / Ethernet
(CC-Link IE Field Network Basic) or using a communication option (FR-A8NC/FR-A8NCE/FR-A8NP). The frequency set for
normal speed control is used as the line speed command value for dancer feedback speed control. (The setting is used as
the set frequency when the X114 signal is OFF, and used as the line speed command value when the X114 signal is ON.)
• The setting range is H0000 to HFFFE (0 to 6553.4), and the setting increment is 0.1.
NOTE
• For the details of RS-485 communication, refer to the FR-A800 Instruction Manual (Detailed). For the details of CC-Link IE
Field Network Basic, refer to the Ethernet Function Manual. For the details of communication options, refer to the Instruction
Manual of each option.
Line speed command input using the FR-A8ND
• The line speed command value is read/written as follows.
Read/write Reading/writing method for line speed command
• Read the Pr.360 setting.
Read
• Writing through I/O communication (Output instance 127).
Write • Write through message communication.
• Write in Pr.360.
• The line speed command value is written through I/O communication (output instance 127) as follows.

• Output instances 20, 21, and 126 and input instances 70, 71, and 176 are not available for the line speed command.
Setting method
0: The values set in bytes 2 and 3 are used as the
speed/frequency setting value.
1: 0.01 Hz increment
0: The format for 16-bit data is being selected.
(Bytes 2 and 3 are used.)
1: The format for 32-bit data is being selected.
(Bytes 2 to 5 are used.)
The line speed command value is written.

Dancer feedback speed control details
1: The values set in bytes 2 and 3 are used as the
writing data to the attributes specified in bytes 6 and
7, respectively.
0: An unexpected value is written. (The value written
in byte 2 and byte 3 is recognized as a number of
rotations. Then, the value is converted into a
frequency value and written as the line speed
command value.)
According to the setting of bit 7 in byte 1, the format
is selected for 16-bit data or 32-bit data.
