RS-485 Installation and Set...
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 frequency converter immediately "lets go"
of the motor (the output transistors are "shut off") and it
coasts to a standstill.
Bit 03='1': The frequency converter 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, only the following conditions
can stop the frequency converter:
•
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 frequency converter 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 leading
edge of the signal, that is, when changing from logic '0' to
logic '1'.

Design Guide
Bit 08, Jog
Bit 08='1': The output frequency depends on3-19 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 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. 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 Control word bit 11 is
chosen in 5-40 Function Relay.
Bit 12, Relay 04
Bit 12="0": Relay 04 is not activated.
Bit 12="1": Relay 04 is activated if Control word bit 12 is
chosen in 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 7.30.
Set-up
Table 7.30 Selection of Set-Up
The function is only possible when 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 Reversing Select. Bit 15 causes reversing
only when Ser. communication, Logic, or Logic and is
selected.
