Introduction
2.4 Universal Registers
Lenze-AC Tech manufactures several drive families. Currently the QC, MC, MCH, SC, TC, smd, Tmd and
SMV Series drives support Modbus based communications. Since each drive family has different parameters
and size ranges, the parameter (register) definitions are in many cases quite different. In order to facilitate
communication in a network with a mix of drive types, certain Lenze-AC Tech Register locations have been
made universal among Lenze-AC Tech drives. While their locations are consistent, their contents may vary
as defined in Table 2.
