1.2.2 DC-bus Sharing: Connecting the DC-bus of the AC Motor Drives
in Parallel
1.
This function is not for 115V models.
2.
The AC motor drives can absorb mutual voltage that generated to DC bus when
deceleration.
3.
Enhance brake function and stabilize the voltage of the DC bus.
4.
The brake module can be added to enhance brake function after connecting in parallel.
5.
Only the same power system can be connected in parallel.
6.
It is recommended to connect 5 AC motor drives in parallel (no limit in horsepower).
