7.2.4

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

C00007

:

• "30:

CAN

" for the connection to the system bus (CAN)

• "40:

MCI

" 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 (

C00011

)

Word 3 -

Not preconfigured

Word 4 -

Not preconfigured

Words 5 ... 16 -

Not preconfigured

• Only available in control mode "40: MCI".

Control word

Name

Function

Bit 0 SwitchOn

1 ≡ Change to the "

SwitchedOn

" device status

• This bit must be set in the CAN/MCI control word to ensure

that the device changes to the

SwitchedOn

" 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

LS_ParFix

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 ModeSpecific_2
Bit 6 ModeSpecific_3
Bit 7 ResetFault

1 ≡ Reset fault (trip reset)

• Acknowledge error message (if the error cause has been

eliminated).

Reset error ( 82)

Bit 8 SetHalt

1 ≡ Activate stop function

• Stop drive via stopping ramp (in preparation).

Bit 9 reserved_1

Reserved (currently not assigned)

Bit 10 reserved_2
Bit 11 SetDCBrake

1 ≡ Activate DC-injection braking

Manual DC-injection braking (DCB) ( 212)

Bit 12 JogSpeed1

Activation of fixed speed 1 ... 3

Bit 13 JogSpeed2
