Inovance MD380 Series

Description of Function Codes
MD380 User Manual
- 240 -
In the master and slave control mode, set this function code of both the master and slave to
0. The master and salve communicate according to the master and slave control frame.
In the droop control mode, set this function code of both the master and slave to 1. The
master and salve communicate according to the droop control frame.
Function Code Parameter Name Setting Range Default
A8-04 Zero offset of received data (torque) -100.00%–100.00% 0.00%
A8-05 Gain of received data (torque) -10.00–10.00 1.00
These two parameters are used to adjust data received from the master and define the
torque reference relationship between the master and the slave.
If "b" expresses the zero offset of received data, "k" expresses the gain, and "y" expresses
the actually used data. The actually used data can be obtained based on the formula:
\ N[E
The value y ranges from -100.00% to 100.00%.
Function Code Parameter Name Setting Range Default
A8-06
Point-point communication interruption
detection time
0.0–10.0s 1.0s
It is used to set the point-point communication interruption time at which this fault is
detected. If it is set to 0, it indicates no detection.
Function Code Parameter Name Setting Range Default
A8-07
Master data sending cycle at
point-point communication
0.001–10.000s
0.001s
It is used to set the data sending cycle of the master in point-point communication.
Function Code Parameter Name Setting Range Default
A8-08 Zero offset of received data (frequency) -100.00%–100.00% 0.00%
A8-09 Gain of received data (frequency) -10.00–10.00 1.00
These two parameters are used to adjust data received from the master and define the
frequency reference relationship between the master and the slave.
If "b" expresses the zero offset of received data, "k" expresses the gain, and "y" expresses
the actually used data. The actually used data can be obtained based on the formula:
\ N[E
The value y ranges from -100.00% to 100.00%.
Function Code Parameter Name Setting Range Default
A8-11 :LQGRZZLGWK 0.20–10.00 Hz 0.5 Hz
This parameter is valid only for the master and slave control mode. Modify the setting to
ensure synchronization of the master and slave speed within the window width.
