Chapter 1 Introduction | 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).
power should be applied at the same time (only the same power system can be connected in parallel) Power 208/220/230/380/440/480 (depend on models) For frame A and B, terminal + (-) is connected to the terminal + (-) of the braking module.
