Bit 00, OFF 1/ON 1:
Normal ramp stop uses the ramp times of the actual selected ramp. Bit 00 = "0": Stops and activates
the output relay 1 or 2, if the output frequency is 0 Hz and if Relay 123 is selected in par. 5-40. Bit
00 = "1": The frequency converter starts if the other start conditions are met.
Bit 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. 5-40. Bit 01 = "1": The frequency
converter starts if the other start conditions are met.
Bit 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": The frequency converter starts if the other start conditions are met.
Bit 03, Coasting/No coasting
Bit 03 = "0": Leads to a stop. Bit 03 = "1": The frequency converter starts if the other start conditions are met.
NB!:
The selection in par. 8-50 Coasting Select determines how bit 03 links with the
