System Integration
NOTICE!
Make a selection in 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 2-01 DC Brake Current and 2-02 DC Braking
Time.
Bit 02=1 leads to ramping.
Bit 03, Coasting
Bit 03=0: The adjustable frequency drive immediately
releases the motor (the output transistors are shut off), and
it coasts to a standstill.
Bit 03=1: The adjustable frequency drive starts the motor if
the other starting conditions are met.
Make a selection in 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 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 (5-10 Terminal 18 Digital Input to 5-15 Terminal 33
Digital Input) programmed to Speed up and Slow-down.
NOTICE!
If freeze output is active, the adjustable frequency drive
can only be stopped by the following:
•
Bit 03 coasting stop
•
Bit 02 DC braking
•
Digital input (5-10 Terminal 18 Digital Input to
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: Permits the adjustable frequency drive to start
the motor if the other starting conditions are met.
Make a selection in 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 signal's
leading edge, for example, when changing from logic 0 to
logic 1.

Design Guide
Bit 08, Jog
Bit 08=1: The output frequency is determined by 3-19 Jog
Speed [RPM].
Bit 09, Selection of ramp 1/2
Bit 09=0: Ramp 1 is active (3-41 Ramp 1 Ramp-up Time to
3-42 Ramp 1 Ramp-down Time).
Bit 09=1: Ramp 2 (3-51 Ramp 2 Ramp-up Time to 3-52 Ramp
2 Ramp-down Time) is active.
Bit 10, Data not valid/Data valid
Tell the adjustable frequency 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 message always contains the control word,
regardless of the message type. Turn off the control word
if it should not be used when updating or reading
parameters.
Bit 11, Relay 01
Bit 11=0: Relay not activated.
Bit 11=1: Relay 01 activated provided that Control word bit
11 is selected in 5-40 Function Relay.
Bit 12, Relay 04
Bit 12=0: Relay 04 is not activated.
Bit 12=1: Relay 04 is activated provided that Control word
bit 12 is selected in 5-40 Function Relay.
Bit 13/14, Selection of set-up
Use bits 13 and 14 to select from the four menu set-ups
according to Table 3.45.
Set-up
Table 3.45 Specification of Menu Set-ups
The function is only possible when [9] Multi Set-Ups is
selected in 0-10 Active Set-up.
Make a selection in 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 digital in 8-54 Reverse Select. Bit 15 causes reversing only
when Ser. communication, Logic or or Logic and is selected.
