Process data assignment for fieldbus communication
The fieldbus communication is connected (preconfigured) to the previously selected technology
application by selecting the corresponding control mode in
• "30:
" for the connection to the system bus (CAN)
• "40:
" for the connection to a plugged-on communication module (e.g. PROFIBUS)
The assignment of the process data words depends only on the application, not on the bus system
used:
Input words
Name
Assignment
Word 1 DriveControl
Control word
• For bit assignment see the table below.
Word 2 MainSetValue
Speed setpoint
• Scaling: 16384 ≡ 100 % reference speed (
)

• Only available in control mode "40: MCI".
Control word
Name
Function
Bit 0 SwitchOn
1 ≡ Change to the "
" device status
• This bit must be set in the CAN/MCI control word to ensure
that the device changes to the "
" device status
after mains connection without the need for a master control
specifying this bit via fieldbus.
• If control via a bus system is not wanted (e.g. in the case of
control via terminals), the wDriveCtrl output signal of the
system block can be connected to the control word
inputs.
Bit 1 DisableVoltage
1 ≡ Inhibit inverter control (pulse inhibit)
Bit 2 SetQuickStop
1 ≡ Activate quick stop (QSP).
Activate/deactivate quick stop ( 81)
Bit 3 EnableOperation
1 ≡ Enable controller (RFR)
• If control via terminals is performed, this bit must be set both
in the CAN control word and in the MCI control word.
Otherwise, the controller is inhibited.
Enable/Inhibit controller ( 80)
Bit 4 ModeSpecific_1
Reserved (currently not assigned)
Bit 5 JogCtrlInputSel1
Binary coded selection of the switch-off position 1 ... 3
• Activation of the signal pairs
bJogCtrlSlowDown1/bJogCtrlStop1,
bJogCtrlSlowDown2/bJogCtrlStop2 or
bJogCtrlSlowDown3/bJogCtrlStop3 according to the
table for activating the pre-switch off
.
Bit 6 JogCtrlInputSel2
Bit 7 ResetFault
1 ≡ Reset fault (trip reset)
• Acknowledge error message (if the error cause has been
eliminated).
Bit 8 bJogCtrlRfgIn
Ramping down of the setpoint generator in the
