MICROMASTER has an extensive range of monitoring functions / messages which
can be used for open-loop process control. The control can either be implemented
in the drive inverter or also using an external control (e.g. PLC). The interlocking
functions in the drive inverter (refer to Section 3.1.2.3) as well as the output of
signals (refer to Section 3.6.2 or 3.7) for external control are implemented using
BICO technology.
The status of the individual monitoring functions / messages are emulated in the
following CO/BO parameters:
r0019 CO/BO: BOP control word
r0052 CO/BO: Status word 1
r0053 CO/BO: Status word 2
r0054 CO/BO: Control word 1
r0055 CO/BO: Supplementary (additional) control word
r0056 CO/BO: Status word – motor control
r0722 CO/BO: Status, digital inputs
r0747 CO/BO: Status, digital outputs
r2197 CO/BO: Messages 1
Frequently used monitoring functions / messages including parameter number and
bit are shown in the following Table.
