V560 Series High Performance Closed-Loop Vector Inverter User Manual
master frequency command * [FA.2.26] of the salve machine.
1: Analog input Al1
If AI1 is selected for the fine adjustment source for linkage proportion coefficient, then: Slave frequency
command = master frequency command * [FA.2.26] of the salve machine *AI1/AI1 maximum.
2: Analog input Al2
If AI2 is selected for the fine adjustment source for linkage proportion coefficient, then: Slave frequency
command = master frequency command * [FA.2.26] of the salve machine *AI2/AI2 maximum.
3: Analog input Al3
If AI3 is selected for the fine adjustment source for linkage proportion coefficient, then: Slave frequency
command = master frequency command * [FA.2.26] of the salve machine *AI3/AI3 maximum.
FA.2.28 Slave machine offset
frequency/revolution
Setting range: 0, 1, 2 Factory default: 0
This parameter of the master inverter does not function, and it is used to select the auxiliary frequency of the
slave machine:
Actual output frequency of the salve machine=master machine frequency command * slave machine linkage
proportion (including fine adjustment) + offset frequency
0: No offset
No offset frequency/revolution; the frequency set value of the slave machine is determined by the frequency
command of the master device and the setting of FA.2.26 and FA.2.27.
1: Determined by frequency setting source 1
The frequency set value of the slave machine frequency setting source 1 is regarded as the offset
frequency/revolution of the slave machine.
2: Determined by frequency setting source 2
The frequency set value of the slave machine frequency setting source 2 is regarded as the offset
frequency/revolution of the slave machine.
FA.2.29 Coupling balance function Setting range: 0~4 Factory default: 0
0: Void
1: Current balance
With reference to the load current of the master device, each slave device will automatically conduct fine
adjustment to the output of local device so as to keep consistency with the master device’s current.
2: Torque balance
With reference to the torque of the master device, each slave device will automatically
7.
3: Power balance
Each slave motor refers to the main motor power，automatic self-adjustment it’s output to ensure the
relatively consistent with the main motor power。
4: position synchronous balance
In the multi-motor linkage system with PG close loop vector control, to use the position synchronous balance
is able to eliminate the accrued displacement deviation caused by the minor deviation of driver rotate speed.
This method requires the motor that runs with linkage has the same parameter in the PG speed detector .
Position synchronous balance can only revise the minor rotate speed deviation. Adjust the synchronous
rotate speed function before use the function.
