Table 11.22 Bit Values for Control Word, PROFIdrive Profile
Explanation of the control bits
Bit 00, OFF 1/ON 1
11 11
Normal ramp stops 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 [31] Relay
123 has been selected in parameter 5-40 Function Relay.
When bit 00=1, the drive is in State 1: Switching on
inhibited.
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 [31] Relay 123 has been selected in
parameter 5-40 Function Relay.
When bit 01=1, the drive is in State 1: on inhibited. Refer
to Table 11.23 at the end of this section.
Bit 02, OFF 3/ON 3
Quick stop using the ramp time of parameter 3-81 Quick
Stop Ramp Time.
When 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
[31] Relay 123 has been selected in parameter 5-40 Function
Relay.
When bit 02=1, the drive is in State 1: Switching on
inhibited.
Bit 03, Coasting/No coasting
Coasting stop bit 03=0 leads to a stop.

VLT® AutomationDrive FC 361
When bit 03=1, the drive can start if the other start
conditions are satisfied.
NOTICE
The selection in parameter 8-50 Coasting Select
determines how bit 03 is linked with the corresponding
function of the digital inputs.

Stop Ramp Time.
No coasting
When bit 04=0, a quick stop occurs.

function again; operation 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 [31] Relay 123
has been selected in parameter 5-40 Function Relay.
Bit 06=0 leads to a stop.
When bit 06=1, the drive can start if the other start
conditions are fulfilled.
NOTICE
The selection in parameter 8-53 Start Select determines
how bit 06 is linked with the corresponding function of
the digital inputs.
Bit 07, No function/Reset
Reset after switching off.
Acknowledges event in fault buffer.
When bit 07=0, no reset occurs.
When there is a slope change of bit 07 to 1, a reset occurs
after switching off.
Bit 08, Jog 1 OFF/ON
Activates the pre-programmed speed in parameter 8-90 Bus
Jog 1 Speed. JOG 1 is only possible if bit 04=0 and bit 00–
03=1.
Bit 09, Jog 2 OFF/ON
Activates the pre-programmed speed in parameter 8-91 Bus
Jog 2 Speed. JOG 2 is only possible if bit 04=0 and bit 00–
03=1.
Bit 10, Data invalid/valid
Tells the drive whether the control word should be used or
ignored.
