9 Control / reference value
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.

et 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 followin
g
explanations and descriptions, the standardized
designations control word and status word are used.
The control of the frequency inverter can be done with three operation modes. They
are set via the data set change-over capable parameter
Local/Remote 412.
Parameter Setting
No. Description Min. Max. Fact. sett.
412 Local/Remote 0 44 44
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.
Operation mode Function
0 -Control via contacts
T
he Start and Stop command as well as the statement
of the direction of rotation are via digital signals.
1 -
Control via
state machine
The Start and Stop command as well as the statement
of the direction of rotation are via the DRIVECOM State
machine of the communication interface.
2 -
Control via
remote contacts
T
he Start and Stop command as well as the statement
of the direction of rotation are via logic signals by the
communication protocol.
Control word STW and state word ZSW have differin
g
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 accordin
g to DRIVECOM. In this way, there
is compatibility to CANopen DS402.
Note:
The parameter
Local/Remote 412 is data set change-over capable. Thus,
switchin
g 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).
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
D
ata
set selection
414 is used.
Parameter Setting
No. Description Min. Max. Fact. sett.
414 Data set selection 0 4 0
With
Data set selection 414 = 0, the data set switch-over via contact inputs is active.
If
Data set selection 414 has been set to 1, 2, 3, or 4, the data set selected in this
way has been activated. The data set switch-over via the contact inputs is then
deactivated.
