Set Up Master Station Number And Communication Speed; Coding - Delta C2000 series User Manual

Example: 1 cycle is 2ms, speed= 1000k, max PDO value is 2*1000/250 = 8. If user
wants to set the cycle time to 2ms, turns off 4 of the C type AC motor drive slave
stations must be turned off (since the pre-defined setting is 8 slaves, half of the
slave station would be 4). The slave station can be turned off by setting the
D2000+n*100 of the unused slaves to 0.
Number of control station ≤ 8.
Controlling 8 slave stations at once can only be done by asynchronous control where
to Read/Write the slave is done by CANRX and CANTX command. This is similar to
the Read/Write action of Modbus protocol.
The slave complies with DS402 standard.
Does not control Slave IO terminal.
If above conditions do not apply, please set up the slave corresponding addresses
manually by open WPL editor > communication> Edit Register Memory (T C D).
Step 3: Set up Master station number and communication speed.
Set up the station number for the Master (the default setting of Pr.09-46=100). Do not
to set the same station number as the Slave.
Set up CANopen communication parameter Pr.09-37. 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
Editor setting at Setting> Communication Setting)
Step 5: Setting the Slave station number, communication speed, operation
source and command source
CANopen communication is supported by Delta C2000 series and EC series AC motor drive.
The corresponding slave and CANopen speed are shown as below:
