Monitor Registers (Read Only)
The following table lists monitor parameters for the G7 drive. These parameters are used to monitor G7 drive information and cannot be written.
The “U-##” column contains the reference, if it exists, to the “U” monitor, parameter displayed via the operator keypad.
The “Address” column contains the register addresses for that parameter in hexadecimal format. G7 drive registers are always referred
to in hexadecimal format.
The “Function” column contains the register name.
The “Bit” column contains the list of available bits for that register. If the “Bit” column is empty, the register contains word data and
the individual bits are meaningless.
The “Description” column contains a short description of each register or register bit.
Reserved registers and data are meaningless and should be ignored.
