7.4.3 Interface description
7.4.3.1 wDriveControl control word
In the control mode "40: Network (MCI/CAN)", the controller is controlled by a master control (e.g.
IPC) via the wDriveControl control word.
• The process data word received from the master control is provided to the application via the
upstream port block LP_Network_In at the wDriveControl input.
• Display parameter: C00136/1
• The bit assignment of the control word can be obtained from the following table:

All input and output interfaces are described in the subchapter entitled " Interface
description " of the "speed actuating drive" application. ( 206)
Bit 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 ( 65)
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 ( 65)
Bit 4 ModeSpecific_1 Reserved (currently not assigned)
Bit 5 InputSel1 Binary coded selection of the switch-off position 1 ... 3
• Activation of the signal pairs bSlowDown1/bStop1, bSlowDown2/bStop2 or
bSlowDown3/bStop3 according to the Truth table for activating the pre-
switch off .
Bit 6 InputSel2
Bit 7 ResetFault 1 ≡ Reset fault (trip reset)
• Acknowledge error message (if the error cause has been eliminated).
 Reset error ( 66)
Bit 8 Rfg0 Ramping down the setpoint generator in the downstream FB L_NSet_1
according to the Truth table for activating the pre-switch off
Bit 9 reserved_1 Reserved (currently not assigned)
Bit 10 reserved_2
Bit 11 LenzeSpecific_1
Bit 12 JogSpeed1
Binary coded selection of the fixed setpoints (JOG setpoints)
Bit 13 JogSpeed2
Bit 14 SetFail
1 ≡ Set error (trip set)
Bit 15 LenzeSpecific_4 Reserved (currently not assigned)
