How to Program
NOTE
The selection in par. 8-50 Coasting Select determines how bit 03 links w ith the
corresponding function of the digital inputs.
B
it 04, Quick stop/ Ramp
Quick stop uses the ramp time of par. 3-8 1. 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 freq uency output/Use ramp
Bit 05 = "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 selected ramp times of the actual ramp. In addition, activation of the output
relay 01 or 04 if the output fre quency 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 determ ines how bit 06 links wi th the corresponding
function of the digital inputs.
B
it 07, N o function/Reset
Reset after switching off. Acknowledges event in fault buffer. B
it 07 = "0": No reset occurs. A
reset occurs after switching off, when there is a slope change of bit 07 to "1".
B
it 08, Jog 1 OFF/ON
Activation of the pre-p rogrammed speed in par. 8-90 Bus Jog 1 speed. JOG 1 is only
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
if bit 04 = "0" and bit 00 - 03 = "1". If both JOG 1 and JOG 2 are activated (bit 08 and 09 =
"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 cha nnel (PCD) should respond
to modifications by the master (bit 10 = 1) or not.
B
it 11, No function/Slo w down
Reduces the speed reference value by the amo
untgiveninpar. 3-12Catch Up/Slow Down Value.Bit11
= "0": The reference value is not modified. Bit 11 = "1": The r efe r ence value is reduced.
B
it 12, No function/Catch up
Increases the speed refe rence value b y 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 do wn a nd acc elerating are activated (bit 11 and 12 = "1"), slowing
down has priority. Thus, the speed reference value is reduced.
