  • Product Detail

Command registers are those used to control the operation of the AC drive either through a network interface (option card) or via serial communication (defined as Modbus built into the drive’s keypad port or terminal strip). These registers are available during an active run command. It should be noted that multi-function digital inputs that are commanded over a communication network are logically OR’d with their physical digital input terminal counterpart.

The “Address” column contains the register address in hexadecimal format. AC drive registers are always referred to in hexadecimal format. The “Function” column contains the register name. The “Bit” and “Description” columns contain the list of available bits for that register and a short description of each. If the “Bit” column is empty, the register contains word data and individual bits have no meaning. Broadcast Registers are those registers used to control the simultaneous operation of multiple devices either through a network interface (option card) or via Modbus RTU communication. These registers are available during drive Run. The “Address” column contains the register address in hexadecimal format. Drive registers are always referenced in hexadecimal format.
