This slide shows a block diagram for an AC-servo amplifier and inverter. For IPM driver couplers, TLP104, TLP2404 and TLP714 cover 1 Mbit/s speed, and the TLP2355, TLP2358, TLP2405, TLP2408 and TLP715 cover 5 Mbit/s. The 1 Mbit/s couplers have a supply current spec of less than 1.6 mA, which can help to reduce system power consumption. The 5 Mbit/s couplers are lower input type, having a threshold input current specification of less than 1.6 mA.
