FC 300 Profibus
Bit 03, Coasting/No coasting
Coasting stop Bit 03 = "0" leads to a stop. When bit 03 = "1", the frequency converter can start if the other
start conditions are satisfied.
NB!:
The selection in par. 8-50 Coasting select determines how bit 03 is linked with the corresponding
function of the digital inputs.
Bit 04, Quick stop/Ramp
Quick stop using the ramp time of par. 3-81 Quick stop ramp time.
When bit 04 = "0", a quick stop occurs.
When bit 04 = "1", the frequency converter can start if the other start conditions are satisfied.
NB!:
The selection in par. 8-51 Quick stop select determines how bit 04 is linked with the corresponding
function of the digital inputs.
Bit 05, Hold frequency output/Use ramp
When bit 05 = "0", the current output frequency is being maintained even if the reference value is modified.
When bit 05 = "1", the frequency converter can perform its regulating function again; operation occurs
according to the respective reference value.
Bit 06, Ramp stop/Start
Normal ramp stop using the ramp times of the actual ramp as selected. In addition, activation of the
output relay 01 or 04 if the output frequency is 0 Hz if Relay 123 has been selected in par. 5-40 Function
relay. Bit 06 = "0" leads to a stop. When bit 06 = "1", the frequency converter can start if the other
start conditions are satisfied.
NB!:
The selection in par. 8-53 Start select determines how bit 06 is linked with the corresponding
function of the digital inputs.
Bit 07, No function/Reset
Reset after switching off.
Acknowledges event in fault buffer.
When bit 07 = "0", no reset occurs.
When there is a slope change of bit 07 to "1", a reset occurs after switching off.
Bit 08, Jog 1 OFF/ON
Activation of the pre-programmed speed in par. 8-90 Bus Jog 1 speed. JOG 1 is only possible if bit 04
= "0" and bit 00 - 03 = "1".
Bit 09, Jog 2 OFF/ON
Activation of the pre-programmed speed in par. 8-91 Bus Jog 2 speed. JOG 2 is only possible if bit 04
= "0" and bit 00 - 03 = "1".
Bit 10, Data invalid/valid
Is used to tell the frequency converter whether the control word is to be used or ignored. Bit 10 = "0"
causes the control word to be ignored, Bit 10 = "1" causes the control word to be used. This function
is relevant, because the control word is always contained in the telegram, regardless of which type of
telegram is used, i.e. it is possible to turn off the control word if you do not wish to use it in connection
with updating or reading parameters.
Bit 11, No function/Slow down
Is used to reduce the speed reference value by the amount given in par. 3-12 Catch up/slow down value.
When bit 11 = "0", no modification of the reference value occurs. When bit 11 = "1", the reference value
is reduced.
