Bit 00, OFF 1/ON 1:
Normal ramp stop uses the ramp tim es of the currently selected ramp. B it 00 = "0": Stops and activates
the output relay 1 or 2, if the output frequency is 0 Hz and if Relay 123 is sel ected in par. 5-40. Bit
00 = "1": The adjustable frequency drive starts if the other s
tart conditions are met.
B
it 01, OFF 2/ON 2
Bit 01 = "0": Coasting stop and activation of the output relay 1 or 2 occurs if the output
frequency is 0 Hz and if relay 123 is selected in par. 5-4 0. Bit 01 = "1": The adjustable
frequency drive starts if the other start conditions are me
t.
B
it 02, OFF 3/ON 3
A quick stop uses the ramp time of par. 2-12. Bit 02 = "0": A quick stop and activation of the output
relay 1 or 2 occurs if the output frequency is 0 Hz and if relay 123 is selected in par. 5-40. Bit 02 =
"1": Theadjustablefrequencydrivestartsiftheot
her start conditions are met.
B
it 03, Coast i ng/No coasting
