How to Program
NOTE
The selection in par. 8-50 Coasting Select determines how bit 0 3 links with the
corresponding function of the digital inputs.
B
it 04, Quick stop/Ramp
Quick stop uses the ramp time of par. 3-81. Bit 04 = "0": A quick stop occurs. Bit 04 = "1":
The adjustable frequency drive starts if the other start conditions are met.
NOTE
The selection in par. 5-51 Quick Stop Select determ ines how bit 04 links with the
corresponding function of the digital inputs.
B
it 05, Hold frequency output/ Use ramp
Bit 0 5 = "0": Maintains the current output frequency even if the reference value is modified.
Bit05="1": Theadjustablefrequencydriveperforms its regulating function again. Operation
occurs ac cording to the respective reference value.
B
it 06, Ramp stop/Start
Normal ramp stop uses the sel ecte d ramp times of the current ramp. In addition, activation of the output
relay 01 or 04 if the output frequency is 0 Hz if relay 123 is selected in par. 5-40. Bit 06 = "0": Leads to a
stop. B it 06 = "1": The adjustable frequency drive starts if the other start con
ditions are met.
NOTE
The selection in par. 8-53 determines how bit 06 links with the corresp onding
function of the digital inputs.
B
it 07, No function/Reset
Reset after switching off. Acknowled ge s event in fault buffer. B
it 07 = "0": No reset occurs. A
reset occurs after switching off, when there is a slope change of b it 07 to "1".
B
it 08, Jog 1 OFF/ ON
Activation of the pre-programmed speed in par. 8-90 Bus Jog 1 Speed .Jog1isonly
possible if bit 04 = "0" and bit 00 - 03 = "1".
B
it 09, Jog 2 OFF/ ON
Activation of the pre-programmed speed in par. 8-91 Bus Jog 2 Speed. Jog 2 is only possible
ifbit04="0"andbit00-03="1". IfbothJog1andJog2areactivated(bit08and09=
"1"), Jog 3 is selected. Thus, the speed (set in pa
r. 8 - 9 2 ) i s u s e d .
B
it 10, Data invalid/valid
Notifiestheadjustablefrequencydriveifthe process data channel (PCD) should respond
to modifications by the master (bit 10 = 1) or not.
B
it 11, No function/Slow-down
Reduces the speed reference value by the amo
untgiveninpar. 3-12Catch up/Slow-down V alue.Bit11
= "0 " : The reference value is not mod ified. Bit 11 = "1": The refe r ence value is reduced.
B
it 12, No function/Catch u p
Increases the speed reference value by the amount given in par. 3-12 Catch up/Slow-down
Value. Bit 12 = "0": The reference valu
e is not modified. Bit 12 = "1": The reference value is
increased. If both slowing down and acc elerating are activated (bit 11 and 12 = "1"), slowing
down has priority. Thus, the speed reference value is reduced.
