Function Code Parameter Name Setting Range Default
A8-02
Selection of action of
the slave in point-point
communication
Whether to send fault
information to master
when a fault occurs
0: No
1: Yes
Whether to follow
master command
0: No
1: Yes
Whether to alarm when
it becomes offline
0: No
1: Yes
011
When AC drive is the slave (A8-01 = 1) in serial comms. control (F0-02 = 2), this function
determines whether it follows the master to run/stop, whether it sends fault information to

slave. It is applicable to droop control or speed synchronization control (slave in
speed control). In load sharing control (slave in torque control), the master sends its
output frequency to the slave. In this case, ensure F8-15 = 0.
Ɣ
A8-03 = 1: The master sends its frequency reference to the slave.
Function Code Parameter Name Setting Range Default
A8-04
Zero offset of received data
-100.00 to 100.00
0.00
A8-05
Gain of received data
-10.00 to 10.00
1.00
These two function parameters correct received data.
Function Code Parameter Name Setting Range Default
A8-06
Point-point communication
interruption detection time
0.0s to 10.0s
1.0s
This function parameter sets time required to detect communication interruption of the
master or slave. To disable the detection function, set this parameter to 0.
Function Code Parameter Name Setting Range Default
A8-07
Master data sending
cycle in point-point
communication
0.001s to 10.000s
0.001s
This function parameter sets data sending cycle of the master in point-point
communication.
Function Code Parameter Name Setting Range Default
A8-11
Window width
0.20 to 10.00 Hz
0.5 Hz
This function parameter is effective only for the master and slave control mode. Modify
the setting to ensure synchronization of the master and slave speed within window width.
