Function Code Parameter Name Setting Range Default
A8-02
Selection of action of
the slave in point-point
communication
0: No
1: Yes
011
Units positiion: whether to follow
master's command
Tens position: whether to send
fault information to master when
a fault occurs
Hundreds position digit: whether
to alarm when it becomes ofine
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
the master when a fault occurs, and whether it alarms when it becomes ofine.
Function Code Parameter Name Setting Range Default
A8-03
The slave received data 0: Output frequency
1: Frequency reference
0
● A8-03 = 0: If F8-15 ≠ 0, the master sends its frequency after droop control to the
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.
● 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. When A0-00 = 0, they correct
frequency reference. When A0-00 = 0, they correct torque reference.
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.
