Status Word According To Fc Profile (Stw) - Danfoss VLT PROFIBUS DP MCA 101 Programming Manual

Control
NOTICE
If freeze output is active, stop the frequency converter
with
•
Bit 03 coast stop.
•
Bit 02 DC brake.
•
Digital input (parameter 5-10 Terminal 18 Digital
Input to parameter 5-15 Terminal 33 Digital
4 4
Input) programmed to DC braking, coasting stop,
or reset and coasting stop.
Bit 06, ramp stop/start
Bit 06=0 stops the frequency converter and the motor
speed ramps 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 have been fulfilled.
NOTICE
In parameter 8-53 Start Select, define how bit 06 ramp
stop/start gates with the corresponding function on a
digital input.
Bit 07, reset
Bit 07=0 does not cause a 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=0, no function.
Bit 08=1, parameter 3-19 Jog Speed [RPM] determines the
output frequency.
Bit 09, selection of ramp 1/2
Bit 09=0, ramp 1 is active (parameter 3-40 Ramp 1 Type to
parameter 3-47 Ramp 1 S-ramp Ratio at Decel. Start).
Bit 09=1, ramp 2 is active (parameter 3-50 Ramp 2 Type to
parameter 3-57 Ramp 2 S-ramp Ratio at Decel. Start).
Bit 10, data not valid/data valid
Tells the frequency converter to use or ignore the control
word.
Bit 10=0 ignores the control word.
Bit 10=1 uses the control word. This function is relevant,
because the control word is always contained in the
telegram, regardless of which type of telegram is used.
Thus, it is possible to turn off the control word, if it is not
needed when updating or reading parameters.
Bit 11, relay 01
Bit 11=0, relay 01 is not activated.
Bit 11=1, relay 01 is activated, provided control word bit 11
is selected in parameter 5-40 Function Relay.
Bit 12, relay 04
Bit 12=0, relay 04 is not activated.
Bit 12=1, relay 04 is activated, provided [37] Control word
bit 12 is selected in parameter 5-40 Function Relay.

Bit 13/14, selection of set-up
Use bits 13 and 14 to select from the 4 menu set-ups
according to Table 4.10:
The function is only possible when [9] Multi Set-ups is
selected in parameter 0-10 Active Set-up.
Table 4.10 Set-up selection
NOTICE
In parameter 8-55 Set-up Select, define how bit 13/14
gates with the corresponding function on the digital
inputs.
Bit 15 reverse
Bit 15=0 means no reversing.
Bit 15=1 means reversing.
4.5.2 Status Word According to FC Profile
The status word is used to inform the master (for example
a PC) of the operating mode of the slave (frequency
converter).
Refer to chapter 7 Application Examples for an example of a
status word telegram using PPO type 3.
