CANopen and CANlink Communication
‑59‑
Assign a value for the D element corresponding to the control word of the required
station number to enable the AC drive to run forward or backward or stop. The
control word is defined as follows:
1: Forward run 2: Reverse run 3: Forward jog 4: Reverse jog 5: Coast to stop 6:
Decelerate to stop 7: Fault reset
The procedure is as follows:
The control word corresponds to the PLC soft element address D7000. When the
D7000 value is set to 1, the AC drive runs forward. To decelerate to stop, set D7000
to 6.
3. Read bus voltage
Read the bus voltage (a) and then divide (a) by 10 to get the actual bus voltage.
Based on the communication configuration, the D element address of the bus
voltage is D7425. Therefore, convert D7425 to a floating‑point number and then
divide the conversion result by 10.
The procedure is as follows:
4. Read output voltage
Based on the communication configuration, you can move or not move the D7408
value to another D element.
The procedure is as follows:
5. Read output current
Based on the conversion rule, divide the reading by 100 to get the actual output
current.
The procedure is as follows:
