Control / Reference Value - BONFIGLIOLI ACTIVE Manual

9
A control gives its control commands (control word) to the frequency inverter via the
object 0x6040/0 control word and receives the information about its status (status
word) back via the object 0x6041/0 status word.
A control gives its reference speed to the frequency inverter (mapped onto the
reference line value) via the object 0x6042/0 target velocity and receives the actual
speed via the object 0x6044/0 control effort.
Note:
The control of the frequency inverter can be done with three operation modes. They
are set via the data set change-over capable parameter
No.
412 Local/Remote
For operation on the CANopen, only the settings 0, 1 and 2 are relevant. The further
settings relate to the possibilities of control via the KP500 control unit.
Control word STW and state word ZSW have differing contents as a function of the
operation mode. In each case, all or only some of the bits in the control word are
relevant and also only certain feedbacks are possible via the status word. These are
then explained in the descriptions of the three possible operation modes.
Control and state word have been created according to DRIVECOM. In this way, there
is compatibility to CANopen DS402.
Note:
The data set change-over can be done locally at the frequency inverter via contact
inputs or via the bus. For the data set change-over via the bus, the parameter

Control / reference value

The objects 0x6040/0 control word, 0x6041/0 status word, 0x6042/0
target velocity and 0x6044/0 control effort are contents of the available
Rx/TxPDO's. Detailed information is to be found in the previous chapters.
In the following explanations and descriptions, the standardized
designations control word and status word are used.

The parameter
switching over between various operation modes via the data set
selection is possible. For example, it is possible to control an frequency
inverter via the bus and to activate a local emergency operation if the bus
master breaks down. This switch-over is also visible via the state word
(Bit Remote).
414 is used.
