3.3 Main Circuit Connection Diagram
Refer to diagrams in this section when wiring the main circuit of the drive. Connections may vary based on drive capacity.
The DC power supply for the main circuit also provides power to the control circuit.

u 12-Pulse/18-Pulse Rectification
Operation with 12-pulse/18-pulse rectification requires the user to separately prepare a 3-winding/4-winding transformer for
the power supply. Contact Yaskawa or your nearest sales representative for the transformer specifications.
n Wiring to –M/+M Terminals (2A0011 to 2A0273 and 4A0005 to 4A0302)
Access the –M/+M terminals by cutting off the protection cover on models 2A0011 to 2A0114 and 4A0005 to 4A0096 or by
removing the protection sheet on –M/+M terminals on models 2A0143 to 2A0273 and 4A0124 to 4A0302.
–M/+M are for rectification options only. Do not use for dynamic braking or line-regeneration.
