CANopen and CANlink Communication
‑52‑
Baud Rate: Upon computer setting (the baud rate of CAN communication for PLC
initialization must be the same as that of the AC drive)
3. Click
and then click ""AAdddd CCAANN CCoonnffiigg"". Next, double‑click
""CCAANNlliinnkk CCoonnffiigg"" and click ""NNeexxtt"" on the page displayed, and then set the
parameters as follows on the page displayed next.
a. Set the slave type to MD (AC drive).
b. Set the slave station number to the value of Fd‑02 of the AC drive.
c. Set 7000 and 6000 for the status register and start/stop element.
d. Click ""AAdddd"" and then ""FFiinniisshh"".
In this way, a slave is added. If the AC drive has multiple axes, click ""AAdddd"" and then
repeat the preceding steps.
4. Write operation: After a slave is added, select PLC to set the configuration to be
written to the D element of the AC drive.
As shown in the preceding figure, assign the D2 value to the control word address
of the AC drive whose station number is 1, and assign the D102 value to the control
word address of the AC drive whose station number is 2. Write the register address
as needed. Ensure that the address of the receiving register is correct and writable.
5. Read operation: Select the station (AC drive) to read and enter the page of
configuration for reading AC drive D element.
To read station 1, click 1 to configure. To read station 2, click 2. If the station
number is incorrect, the required value cannot be read.
As shown in the preceding figure, send the bus voltage, output voltage, and output
frequency of the AC drive to D300, D302, and D304 of the PLC. Correctly configure
the sending register address and D element as needed. After finishing all write and
read configurations, click ""OOKK"" continuously to go back to the programming page.
