The Gen2 Regenerative Drive is designed to be compatible with both MCSS-type and TCBC-type controllers. As a result, two of the fundamental operating modes of the drive are MCSS mode and CAN mode. The setting of the service tool parameter Interface Type specifies which controller is to be used and determines the fundamental operating mode. The mode determines the source of the motion commands and other functionality of the drive. Additionally, there are sub-modes, each of which is described below.
