 Set up CANopen communication speed to 1 M (parameter Pr.09-37= 0). It does not

matter if the drive is defined as a Master or a Slave, communication speed is set by

Pr.09-37 in both case.

Step 4: Coding

Real-time corresponding action: the data can be Read/Write directly to the corresponding

special “D” register.

Non Real-time corresponding action:

Read: Reading is made by CANRX command. When reading process is complete,

M1066=1. If reading succeeded, M1067 =1; if reading failed, M1067= 0.

Write: Writing is made by CANTX command. When writing process is complete, M1066

=1. If writing succeeded, M1067=1; if reading failed, M1067 =0.

Update: Updating the data is made by CANFLS command. (If special D register is defined

as RW type, Master will write the value into the slave. If special D register is

defined as RO type, then the data in the Slave will be read and write into the

Master.) When updating process is complete, M1066 will be 1. If updating

succeeded, M1067=1; if updating failed, M1067=0.

NOTE

When executing CANRX, CANTX and CANFLS commands, the device will wait till M1066 is completed before

the next CANRX, CANT or CANFLS begins. When the commands completed, download the program to the

drive. (Note: The factory setting of PLC communication protocol is ASCII 7N2 9600 and station number is 2.

Please change WPL setting at setting> communication setting)

Step 5: Set Slave station number and communication speed.

Slave No.1: Pr.09-37 = 0(speed 1M), Pr.09-36=10 (station number 10)

Slave No.2: Pr. 09-37 = 0(speed 1M), Pr.09-36=10 (station number 11)

Step 6: Hardware connection

The terminating resistor must be installed at the two farthest ends as shown in the figure

below:

Step 7: Activate PLC Control Function

Download the program after coding is complete and switch PLC mode to Run status. Then

reboots the power for Slave and Master. Please refer to CAN Master Test 1 vs. 2 driver.dvp.
