Group 7: Control words
It is possible to write on all signals in this group - except UsedMCW (7.04) - my means of DWL, DCS Control
Panel, AP or overriding control.
7.01 MainCtrlWord (main control word, MCW)
The main control word contains all drive depending commands and can be written to by AP or overriding control:
Bit
Name
Value Comment
B0
On (Off1N)
1
Command to RdyRun state.
With MainContCtrlMode (21.16) = On: Closes contactors, starts field exciter and fans.
With MainContCtrlMode (21.16) = On&Run:
RdyRun flag in MainStatWord (8.01) is forced to 1
0
Command to Off state. Stopping via Off1Mode (21.02).
B1
Off2N
1
No Off2 (Emergency Off / Coast Stop)
0
Command to OnInhibit state. Stop by coasting. The firing pulses are immediately set to 150
degrees to decrease the armature current. When the armature current is zero the firing pulses
are blocked, the contactors are opened, field exciter and fans are stopped.
Off2N has priority over OffN3 and On.
B2
Off3N
1
No Off3 (E-stop)
0
Command to OnInhibit state. Stopping via E StopMode (21.04).
Off3N has priority over On.
B3
Run
1
Command to RdyRef state. The firing pulses are released and the drive is running with the
selected speed reference.
0
Command to RdyRun state. Stop via StopMode (21.03).

no action
0
speed ramp output is forced to zero
B5
RampHold
1
no action
0
freeze (hold) speed ramp
B6
RampInZero 1
no action
0
speed ramp input is forced to zero
B7
