5-4-3 Inputting Control/Frequency
The Inverter’s various control inputs are allocated to the registers shown in the following table. For ex-
ample, to set the frequency reference and begin operation, first set the reference value to the frequency
reference register “0001,” and then write the run command to the Inverter’s run command register
“0000.”
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.
