The compact design of the drive can reduce mounting space up to 32%. The drive is backward compatible, for a seamless conversion of customers' existing Altivar 18 AC drives. An RS485 MODBUS serial link built into ALTIVAR 28 AC drives provides interconnection with network systems such as MODBUS Plus, Ethernet TCP/IP and DeviceNet. Motor performance feedback allows increased uptime and efficient production, while versatile programmability eliminates the need for additional programming expense. The drive's simplified design, with fewer parts and fewer internal electrical connections, leads to optimum reliability. Convenient fault resets simplify operation and maintenance.
