8400 StateLine C | Reference manual
Device control (DCTRL)
Internal interfaces | "LS_DriveInterface" system block
104 L Firmware ≤ 11.00 - DMS 8.0 EN - 10/2011
Tip!
If a bus control is not wanted (e.g. in case of control via terminals):
Connect both control word inputs with the wDriveCtrl output signal of the
LS_ParFix
system block. This output signal has the fixed value "9", which
corresponds to the following assignment:
• Bit 0, SwitchOn = 1
• Bit 3, EnableOperation = 1
• All others: 0
4.4.2 wDeviceStatusWord status word
The wDeviceStatusWord status word provided by the control system contains all
information relevant for controlling the controller.
The status word is sent as a process data word to the master control via a port block:
–The LP_CanOut1 port block if "CAN on board" is used or
–the LP_MciOut1 port block if a plugged-in communication module is used (e.g.
PROFIBUS).
Display parameter: C00150
The bit assignment of the wDeviceStatusWord status word can be seen from the table
below.
Bit 14 SetFail 1 ≡ Set error (trip set)
Bit 15 LenzeSpecific_4 Assignment depends on the selected technology application
• See description of the corresponding technology application.
Bit Name Function
Bit Name Status
Bit 0 FreeStatusBit0 Free status bit 0
Bit 1 PowerDisabled 1 ≡ Inverter control inhibited (pulse inhibit is active)
Bit 2 FreeStatusBit2 Free status bit 2 (not assigned, freely assignable)
Bit 3 FreeStatusBit3 Free status bit 3 (not assigned, freely assignable)
Bit 4 FreeStatusBit4 Free status bit 4 (not assigned, freely assignable)
Bit 5 FreeStatusBit5 Free status bit 5 (not assigned, freely assignable)
Bit 6 ActSpeedIsZero During open-loop operation:
1 ≡ Speed setpoint < Comparison value (C00024
)
During closed-loop operation:
1 ≡ Actual speed value < Comparison value (C00024
)
Bit 7 ControllerInhibit 1 ≡ Controller inhibited (controller inhibit is active)
Bit 8 StatusCodeBit0 Bit coded display of the active device status
Device state machine and device statuses
(see table [4-1])
Bit 9 StatusCodeBit1
Bit 10 StatusCodeBit2
Bit 11 StatusCodeBit3
Bit 12 Warning 1 ≡ Controller is in the "Warning
" device status
Bit 13 Trouble 1 ≡ Controller is in the "Trouble
" device status
• E.g. if an overvoltage has occurred.
