Description

8–16
8.4 Modbus Memory Map
The data stored in the MM3 Motor Manager 3 is grouped into two areas: setpoints and
actual values. Setpoints can be read and written by a master computer. Actual values can
be read only. All setpoints and actual values are stored as two-byte values. That is, each
register address is the address of a two byte value. Addresses are listed in hexadecimal.
Data values (setpoint ranges, increments, factory values) are in decimal.
