7-9 Programming Examples
– Register and Command
7-9-1 Access Drive Function Setting
– Write Operation
Write a single register to access drive function setting:
Ex: Set function F_031 (primary speed) = 30 Hz
a. Register address: 001FH ( 31 (decimal) = 001FH (hex) )
b. Speed =
：
0BB8H ( 30Hz

30.00Hz(resolution: 0.01Hz)

30.00
÷
0.01 = 3000 (decimal) = 0BB8H (hex)
Code to write to drive register from the host (CRC exclusive)

7-9-2 Host Control to Drive
– Write Operation
When the host control by Modbus communication, user can simply create
an icon or active key/button to activate the drive. The following examples
shows how to program the communication control.
1. Start the drive:
a. Create an icon or active button/key on the host for
―Drive Start‖
b. Program the host with the following code for
―Drive Start‖
c. The drive register to be written for start operation: 2000H
d. The register data for start operation: 0002H
Address OP Code

2. Forward rotation command:
a. Create an icon or active button/key on the host for
―Forward‖
b. Program the host with following code for
―Forward‖ rotation control
c. The drive register to be written for forward command: 2000H
d. The register data for forward command: 0010H
Address OP Code

3. Speed Setting (frequency command)
– without using drive function
setting:
Set the speed to be 30.05Hz (resolution: 0.01Hz)
a. The drive register to be written for Speed setting(frequency
command): 2001H
b. Convert 30.05Hz to hexadecimal value:
30.05 x 100 (by the resolution) = 3005 (decimal) = 0BBDH

4.Primary Acceleration/Deceleration Time Setting:
Set the acceleration/deceleration time = 1.5 seconds (resolution: 0.1
seconds)
a. Set F_019 (Primary accel time) = 1.5 seconds
