Fieldbus control with embedded fieldbus
262
DCU communication profile
Because the DCU profile extends the control and status interface to 32 bits, two
different signals are needed for both the control (0301 and 0302) and status (0303
and 0304) words.
The following tables describe the Control Word content for the DCU profile.
DCU Profile Control Word (parameter 0301)
Bit
Name
Value
Information
0
STOP
1
Stop according to either the stop mode parameter (
) or the stop mode requests
(bits 7 and 8).
Note:
Simultaneous STOP and START commands result in a stop command.
0
No operation
1
START
1
Start
Note:
Simultaneous STOP and START commands result in a stop command.
0
No operation
2
REVERSE
1
Reverse direction. The direction is defined by using the XOR operation on bit 2 and 31
(=sign of the reference) values.
0
Forward direction.
3
LOCAL
1
Enter local control mode.
0
Enter external control mode.
4
RESET
-> 1
Reset.
other
No operation
5
EXT2
1
Switch to external control EXT2.
0
Switch to external control EXT1.
6
RUN_DISABLE
1
Activate Run Disable.
0
Activate Run Enable.
7
STPMODE_R
1
Stop along currently active deceleration ramp (bit 10). Bit 0 value must be 1 (=STOP).
0
No operation
8
STPMODE_EM
1
Emergency stop. Bit 0 value must be 1 (=STOP).
0
No operation
9
STPMODE_C
1
Coast to stop. Bit 0 value must be 1 (=STOP).
0
No operation
10
RAMP_2
1
Use acceleration/deceleration ramp pair 2 (defined by parameters
...
).
0
Use acceleration/deceleration ramp pair 1 (defined by parameters
...
).
11
RAMP_OUT_0
1
Force ramp output to zero.
0
No operation
12
RAMP_HOLD
1
Halt ramping (Ramp Function Generator output held).
0
No operation
13
RAMP_IN_0
1
Force ramp input to zero.
0
No operation
14
REQ_LOCALLOC
1
Enable local lock. Entering the local control mode is disabled (LOC/REM key of the
panel).
0
No operation
15
TORQLIM2
1
Use minimum/maximum torque limit 2 (defined by parameters
and
).
0
Use minimum/maximum torque limit 1 (defined by parameters
and
).
