RS-485 Installation and Set...
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 by means of the
digital inputs (5-10 Terminal 18 Digital Input to
5-15 Terminal 33 Digital Input) programmed to Speed up
and Slow down.
NOTE
If Freeze output is active, the frequency converter 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 frequency converter to start the
11 11
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, i.e.
when changing from logic '0' to logic '1'.
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 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, you can turn off the
268
FC 300 Design Guide
control word if you do not want to use it 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 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 provided that Control word bit 12 is chosen in
5-40 Function Relay.
Bit 13/14, Selection of set-up:
Use bits 13 and 14 to choose from the four menu set-ups
according to the shown table: .
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. communi-
cation, Logic or or Logic and is selected.
