Explanation of the Control Bits
Bit 00, OFF 1/ON 1
Normal ramp stop using the ramp times of the actual selected ramp.
Bit 00 = "0" leads to the stop and activation of the output relay 1 or 2 if the output frequency is 0 Hz and if [Relay 123] has been selected in
par. 5-40 Function Relay
When bit 00 = "1", the frequency converter is in State 1: "Switching on inhibited".
Please refer to the PROFIdrive State Transition Diagram, at the end of this section.
Bit 01, OFF 2/ON 2
Coasting stop
When bit 01 = "0", a coasting stop and activation of the output relay 1 or 2 occurs if the output frequency is 0 Hz and if [Relay 123] has been selected
Function Relay
in par. 5-40

When bit 01 = "1", the frequency converter is in State 1: "Switching on inhibited". Please refer to the PROFIdrive State Transition Diagram, at the end
of this section.
Bit 02, OFF 3/ON 3
Quick stop using the ramp time of par. 3-81
the output frequency is 0 Hz and if [Relay 123] has been selected in par. 5-40
When bit 02 = "1", the frequency converter is in State 1: "Switching on inhibited".
Please refer to the PROFIdrive State Transition Diagram, at the end of this section.
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!

inputs.
Bit 04, Quick stop/Ramp
Quick stop using the ramp time of par. 3-81
When bit 04 = "0", a quick stop occurs.
When bit 04 = "1", the frequency converter can start if the other start conditions are satisfied.
