FC 300 Design Guide
• Bit 02 DC braking
• Digital input (par. 5-10 to 5-15) programmed to DC braking, Coasting stop, or Re-
set 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
par. Bit 06 = '1': Permits the frequency converter to start the motor, if the other starting conditions are
met.
NB!
Make a selection in par. 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 par. 3-19 Jog Speed.
Bit 09, Selection of ramp 1/2:
Bit 09 = "0": Ramp 1 is active (par. 3-40 to 3-47). Bit 09 = "1": Ramp 2 (par. 3-50 to 3-57) 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 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 par. 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 par. 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 par. 0-10 Active Set-Up
Bit 15 Reverse:
Bit 15 = '0': No reversing. Bit 15 = '1': Reversing. In the default setting, reversing is set to digital in par.
8-54 Reversing Select. Bit 15 causes reversing only when Ser. communication, Logic or or Logic and is
selected.
