9.6.5. Control Word according to PROFIdrive Profile (CTW)
The Control word is used to send commands
from a master (e.g. a PC) to a slave.
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
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 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
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 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.
Bit 04, Quick stop/Ramp
Function relay
NB!
The selection in par. 8-50 Coasting select determines how bit 03 is linked with the
corresponding function of the digital inputs.
