10-4-1 Inputting Control/Frequency
The Inverter's various control inputs are allocated to the registers shown in the following table. For
example, to set the frequency reference and begin operation, first set the reference value to the fre-
quency reference register “0002,” and then write the run command to the Inverter's run command
register “0001."
Note 1. Set values are retained until changed by the next writing operation.
Note 2. The following registers are in RAM, so they are all cleared to zero when the Inverter's power
supply is turned OFF.
Note 3. When the remote I/O function is being used, the run command and frequency reference are
overwritten at regular intervals.
Note 1. The V/f gain is the setting for the percentage of the V/f calculation result with respect to the
output voltage. A setting of 1000 decimal (03E8 hex) corresponds to a multiplication factor
of 1.
Note 2. When these registers are read, the values set in communications will be read. For example,
when an operation command (register number 0001) is read, the control input previously set
in communications will be returned. It is not a monitor for the actual terminal block input sig-
nals.
