Cautions during Use

• Follow instructions in ‘Cautions during Use’.
  Otherwise, it may cause unexpected accidents.

• Keep away from high voltage lines or power lines to prevent inductive noise.

Communication Interface

RS485

• It is not allowed to change parameter related to THD communication under the communication with high order system.
  (THD and upper system are available to change the address at communication status.)

• Match the parameter of THD communication to be same as the high order system.

• It is not allowed to set overlapping communication address at the same communication line.
  Use twisted pair wire which is appropriate communication cable for RS485 communication.

RS485 Communication

Ordering of communication control

• The communication method is Mod bus RTU.

• After 2.0 sec supplying the power into master system, it is able to start communication.

• The initial communication is started by master system. When a command comes out from the master system, THD will respond.
  

• A → Min. 2.0 sec after supplying power

• B → (Communication Speed × 10) × within 10 times e.g. (1 s / 9600 bit × 10 bit) = 1.04 ms × within 10 times

• C → (Communication Speed × 10) × over 4 times

Communication speed setting

1. Turn off the power of the unit.
2. Set SW1 to 0 and supply the power.
3. Operation indicator LED is flashing.
4. Set a communication speed after choosing SW1 within the range 1 to 8, and hold it for 3 sec.
5. After 3 sec and operation indicator is ON, turn OFF the power.

Communication address setting

1. Set upper address setting terminal and setting switch (SW1) to the desired address and supply the power.
2. The communication address is changed automatically.
   Address| Upper address setting terminal| SW1| Adress| Upper address setting terminal| SW1
   ---|---|---|---|---|---
