7-7 Register Number Allocations in Detail
The following description provides information on register numbers allocated
to the Inverter and the meanings of the registers. As for the register numbers
of the parameters (n01 through n79), refer to Section 10 List of Parameters
and the description of each of these parameters wherever explained in this
manual.
7-7-1 I/O Function
Communications with a Single Slave with Addresses 01 to 32 (01 to 20 Hex)
Read/Write
Note 1. The V/f gain is a rate to be multiplied by the output voltage obtained from
V/f operation. If 1000 (03E8 Hex) is set, the multiplication rate will be 1.
2. When the above registers are read, values that are set through
communications will be read. For example, when the RUN command
(register 0001) is read, the control input in the register that was previously
set through communications will be returned. This is not a value monitored
through the input signal terminal. To monitor the actual status of the
Inverter, use the monitor functions (refer to
7-7-2 Monitor Functions
.
RUN Command (Register 0001 Hex)
Note There is an OR relationship between input from the control terminals and
input through communications, except for the RUN command and forward/
reverse rotation command.
Inverter Output (Register 0009 Hex)
Note The settings will be enabled if multi-function output n40 is set to 18 for
communications output. Then the output terminals (MA to MC) will be turned
ON and OFF through communications.
Register No. (Hex) Function Description
0000 Not used. ---
0001 RUN command Refer to the table below.
0002 Frequency reference Set the frequency reference in the unit according to the set
value in n69.

200.0% (20 to 2000). (See note 1.)
