Commissioning guidelines
-102-
Commissioning method:
Set P28.00 to 1 for the master, set P28.00 to 2 for the slave, and set the ones place of P28.02 to 4
both for the master and slave to select master/slave mode 4.
If there is a transmission ratio between the slave and master, set the P28.07, P28.08 and P28.09.
When the pulse difference between the slave and master is greater than P28.09, a fault is reported
directly. When the pulse difference between the slave and master is less than P28.08, speed
correction is not performed. When the pulse difference between the slave and master is greater than
P28.08 but less than P28.09, speed correction is performed, and adjust P28.12, P28.13, and P28.14
when necessary. In addition, you can set P28.10.
The master sends the running command, speed, and position pulse to the slave through CAN
communication. The slave performs speed correction by comparing the local position pulse with the
position pulse sent from the master.
Note: Open-loop vector control is applicable only to master/slave modes 0
–3, while
closed-loop vector control is applicable to all the master/slave modes.

Ones place: Master/slave running mode
selection
0: Master/slave mode 0
The master and slave use speed control, with
power balanced through droop control.
1: Master/slave mode 1
(The master and slave must be in the same
type of vector control. When the master is in
speed control, the slave is forced into torque
control.)
2: Combined mode (Master/slave mode 2)
The slave switches from speed mode
(master/slave mode 0) to torque mode
(master/slave mode 1) at a frequency point.
3: Master/slave mode 3 (Reserved)
(Both the master and slave adopt speed
control, and the slave performs power balance
