Appendix
NOTICE
Make a selection in parameter 8-56 Preset Reference Select
to define how bit 00/01 gates with the corresponding
function on the digital inputs.
Bit 02, DC brake
Bit 02=0 leads to DC braking and stop. Set braking current
and duration in parameter 2-01 DC Brake Current and
parameter 2-02 DC Braking Time.
Bit 02=1 leads to ramping.
Bit 03, Coasting
Bit 03=0: The drive immediately shuts off 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
define 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 define
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].

Design Guide
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
off 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 11.21.

Table 11.21 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 define
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:
