bit 0: "Switch on"/Contactor command
bit 1: "Disable voltage"/Authorization to supply AC power
bit 2: "Quick stop"/Emergency stop
bit 3: "Enable operation"/Run command

bit 4: Reserved (set to 0)
bit 5: Reserved (set to 0)
bit 6: Reserved (set to 0)
bit 7: "Fault reset"/Fault acknowledgment active on 0 V 1 rising edge

bit 8: "Halt"/Halt. Stop according to the 

 

(Stt)

 parameter without leaving the 5 - Operation enabled state.

bit 9: Reserved (set to 0)

bit 10: Reserved (set to 0)
bit 11: Direction of rotation command. Default assignment; this bit can be assigned to another command.

= 0: Forward rotation
= 1: Reverse rotation

bit 12: Can be assigned to a command
bit 13: Can be assigned to a command
bit 14: Can be assigned to a command
bit 15: Can be assigned to a command

For the description of bits 0, 1, 2, 3, 7 and 8, see the "CiA402 profile" section.

The CiA402 standard enables the drive manufacturer to use bits 11 to 15 in a specific way. On the Altivar 61, they can be 
assigned to function commands. Bit 11 is assigned by default to control the direction of rotation, although it can be assigned 
to another command. A new assignment deletes the assignment to the direction of rotation command. Bits 12 to 15 have no 
default assignment. For example, to control DC injection braking using bit 12 of the Modbus control word, simply set the 

 

(dCI)

) parameter to value 

 

(C212)

.

The fast stop command configured by 

 

(FSt)

 is active at 1:

= 0: No stop command
= 1: Stop

The DC injection braking command configured by 

 

(dCI)

 is active at 1:

= 0: No braking command
= 1: Braking

With a fixed assignment (

pp

], 

pp

], 

pp

] or 

pp

]), the fast stop and DC injection braking commands are priority 

stops, even if the channel is not active. If these commands are configured as fixed assignments, the following settings must 
be made in order to start, even if another channel is active:

• Fast stop command = 0
• DC injection braking command = 0

With a switched assignment (

pp

]), the fast stop and DC injection braking commands are only operational if the channel 

is active.

The freewheel stop 

 

(nSt)

 command cannot be assigned in CiA402 profile.
