FC 300 Design Guide
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
When bit 00 = "1", the adjustable frequency drive 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 in par. 5-40
When bit 01 = "1", the adjustable frequency drive 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
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 in par. 5-40
When bit 02 = "1", the adjustable frequency drive 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 adjustable frequency drive can
start if the other start conditions are satisfied.
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 adjustable frequency drive can start if the other start conditions are sat-
isfied.
Bit 05, Hold frequency output/Use ramp
When bit 05 = "0", the current output frequency is maintained even if the reference value is
modified.
When bit 05 = "1", the adjustable frequency drive can perform its regulating function again; op-
eration occurs according to the respective reference value.
Bit 06, Ramp stop/Start
Normal ramp stop using the ramp times of the actual ramp as selected. In addition, activation of
the output relay 01 or 04 if the output frequency is 0 Hz if Relay 123 has been selected in par.
