2. Drive Frequency Output Readout:
Example: If the drive frequency outputs = 40.65Hz, read the data output
from the drive and display 40.05Hz in the host.
a. The host sends the below codes to access the drive register
to read out the frequency output data (read only one register
data)
-Drive register: 2103H
-Number of register to read: 1

0001H
Message Code (Host to Drive)

b. The drive returns the frequency output readouts to the host
-Output frequency readouts from the drive (2103H register
data):

c. Program the host to convert register data 0FE1H (Hex value)
= 4065 (Decimal value)
d. Display the output frequency (resolution = 0.01): 4065/100 =
40.65 (unit in Hz)
