Danfoss VLT AHF 005 Design Guide

Bit 03, Coasting
Bit 03=0: The drive immediately shuts o the output
transistors and the motor coasts to a standstill.
Bit 03=1: The drive starts the motor if the other starting
conditions are met.
Make a selection in parameter 8-50 Coasting Select to
dene how bit 03 gates with the corresponding function
on a digital input.
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 found in parameter 5-10 Terminal 18 Digital Input –
parameter 5-15 Terminal 33 Digital Input.
NOTICE
If freeze output is active, only the following conditions
can stop the drive:
•
Bit 03 Coasting stop.
•
Bit 02 DC braking.
•
Digital input (parameter 5-10 Terminal 18 Digital
Input – parameter 5-15 Terminal 33 Digital Input)
programmed to DC braking, Coasting stop, or
Reset and Coasting stop.
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 drive to start the motor if the other
starting conditions are met.
Make a selection in parameter 8-53 Start Select to dene
how bit 06 Ramp stop/start gates 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 leading
edge of the signal, that is, when changing from logic 0 to
logic 1.
Bit 08, Jog
Bit 08=1: The output frequency depends on
parameter 3-19 Jog Speed [RPM].
Bit 09, Selection of ramp 1/2
Bit 09=0: Ramp 1 is active (parameter 3-41 Ramp 1 Ramp
Up Time – parameter 3-42 Ramp 1 Ramp Down Time).
Bit 09=1: Ramp 2 (parameter 3-51 Ramp 2 Ramp Up Time –
parameter 3-52 Ramp 2 Ramp Down Time) is active.
Bit 10, Data not valid/Data valid
Tell the drive 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. Thus, it is possible to turn
o the control word if not in use when updating or
reading parameters.
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 04
Bit 12=0: Relay 04 is not activated.
Bit 12=1: Relay 04 is activated if [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 14.21.
Set-up Bit 14 Bit 13
1 0 0
2 0 1
3 1 0
4 1 1
Table 14.21 Selection of Set-Up
The function is only possible when [9] Multi Set-ups is
selected in parameter 0-10 Active Set-up.
Make a selection in parameter 8-55 Set-up Select to dene
how bit 13/14 gates 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 [0] Digital input in parameter 8-54 Reversing Select. Bit 15
causes reversing only when the following is selected:
•
Serial communication
•
Logic or
