Inter-drive communication command(RAM

Write)
This command is for using frequency command values in % (1 = 0.01%), instead of in Hz, and is for
synchronous-proportional operation in inter-drive communication
synchronous-proportional operation in inter-drive communication
.
This command can also be used
in ordinary computer link communications.
When writing in the frequency command (FA01) is enabled and a parameter other than it is specified,
a communication number error will result.
When writing in the frequency command (FA01) is enabled and a parameter other than it is specified,
a communication number error will result.
Data is written in the RAMs only and at this time the data
check such as an upper limit and lower limit checking is not carried out.
Data is not returned from the inverters while this command is used. This command can be used
only in the binary mode.
For the details of the format, see “6.2 Transmission format for inter-drive communication.”
Use (%) as the unit for frequency command values specified by the command S, instead of (Hz), and
the receiving side converts units for frequency values to “Hz” in accordance with the point conversion
parameter. The conversion formula is shown below.

When Command “s” (lowercase letter) is received, the slave side judges that the master side is
tripped and operates in accordance with the inter-drive communication parameter ().

- Examples: 50% frequency command
(If maximum frequency = Frequency for operation at 80Hz = 40Hz: 50% = 5000d = 1388H)
(If maximum frequency = Frequency for operation at 80Hz = 40Hz: 50% = 5000d = 1388H)

(Block Communication Command)
Data selected in the block communication write parameters (,) is written in the
RAMs. When returning data, data selected in block communication read parameters ( to
RAMs. When returning data, data selected in block communication read parameters ( to
