Status Word According To Fc Profile (Stw) - Danfoss VLT Micro Drive FC 51 Design Manual

RS485 Installation and Set-...
Bit 04, Quick stop
Bit 04=0: Makes the motor speed ramp down to stop (set
in parameter 3-81 Quick Stop Ramp Time).
Bit 05, Hold output frequency
Bit 05=0: The present output frequency (in Hz) freezes.
Change the frozen output frequency only with the digital
inputs (parameter 5-10 Terminal 18 Digital Input to
parameter 5-13 Terminal 29 Digital Input) programmed to
[21] Speed up and [22] Slow down.
NOTICE
If freeze output is active, the frequency converter can
only be stopped by the following:
•
Bit 03 coast stop
•
Bit 02 DC brake
•
Digital input (parameter 5-10 Terminal 18 Digital
Input to parameter 5-13 Terminal 29 Digital
Input) programmed to [5] DC-brake inverse, [2]
Coast inverse, or [3] Coast and reset inverse.
Bit 06, Ramp stop/start
Bit 06=0: Causes a stop and makes the motor speed ramp
down to stop via the selected ramp down parameter.
Bit 06=1: Allows the frequency converter to start the motor
if the other starting conditions are met.
Make a selection in parameter 8-53 Start Select to define
how bit 06 Ramp stop/start communicates with the
corresponding function on a digital input.
Bit 07, Reset
Bit 07=0: No reset.
Bit 07=1: Resets a trip. Reset is activated on the signal's
leading edge, that is, when changing from logic 0 to logic
1.
Bit 08, Jog
Bit 08=1: The output frequency is determined by
parameter 3-11 Jog Speed [Hz].
Bit 09, Selection of ramp 1/2
Bit 09=0: Ramp 1 is active (parameter 3-41 Ramp 1 Ramp
Up Time to parameter 3-42 Ramp 1 Ramp Down Time).
Bit 09=1: Ramp 2 (parameter 3-51 Ramp 2 Ramp Up Time to
parameter 3-52 Ramp 2 Ramp Down Time) is active.
Bit 10, Data not valid/Data valid
Tell the frequency converter whether to use or ignore the
control word.
Bit 10=0: The control word is ignored.
Bit 10=1: The control word is used.
This function is relevant because the telegram always
contains the control word, regardless of the telegram type.
Turn off the control word if not wanting to use it when
updating or reading parameters.

Design Guide
Bit 11, Relay 01
Bit 11=0: Relay not activated.
Bit 11=1: Relay 01 activated if [36] Control word bit 11 is
selected in parameter 5-40 Function Relay.
Bit 12, Relay 02
Bit 12=0: Relay 02 is not activated.
Bit 12=1: Relay 02 is activated if [37] Control word bit 12 is
selected in parameter 5-40 Function Relay.
Bit 13, Selection of set-up
Use bit 13 to select from the 2 menu set-ups according to
Table 8.38.
Table 8.38 Set-up Selection
The function is only possible when [9] Multi Set-up is
selected in parameter 0-10 Active Set-up.
Make a selection in parameter 8-55 Set-up Select to define
how bit 13 communicates with the corresponding function
on the digital inputs.
Bit 15 Reverse
Bit 15=0: No reversing.
Bit 15=1: Reversing. In the default setting, reversing is set
to digital in parameter 8-54 Reversing Select. Bit 15 causes
reversing only when 1 of the following options is selected:
[1] Bus, [2] Logic AND, [3] Logic OR.
8.11.2 Status Word According to FC Profile
