Firmware description
Chapter overview
This chapter describes how to control the DCS550 with standard firmware.
Identification of the firmware versions
The DCS550 is controlled by the SCDS-CON-F. Check the firmware version and type from:
−
FirmwareVer (4.01) and
−
FirmwareType (4.02).
Start / stop sequences
General
The drive is controlled by control words [MainCtrlWord (7.01) or UsedMCW (7.04)]. The MainStatWord (8.01)
provides the handshake and interlocking for the overriding control.
The overriding control uses the MainCtrlWord (7.01) or hardware signals to command the drive. The actual
status of the drive is displayed in the MainStatWord (8.01). The marks (e.g.

) describe the order of the
commands according to Profibus standard. Connect the overriding control via:
−
serial communication (e.g. Profibus) or
−
hardware signals - see CommandSel (10.01) = Local I/O
Start the drive
The start sequence given below is only valid for MainContCtrlMode (21.16) = On.
Attention:
Maintain all signals. On- and Run [MainCtrlWord (7.01) bit 0 and 3] commands are only taken over with their
rising edges.
Overriding Control
MainCtrlWord (7.01)
Drive
MainStatWord (8.01)
When the drive is ready to close the main contactor RdyOn
state is set
 
RdyOn = 1; (bit 0)
The overriding control commands On
On = 1; (bit 0)
 
The drive closes the main contactor and the contactors for
converter and motor fans. After the mains voltage and all
acknowledges are checked and the field current is
established, the drive sets state RdyRun.
 
RdyRun = 1; (bit 1)
The overriding control commands Run
Run = 1; (bit 3)
 
The drive releases the ramp, all references, all controllers
and sets state RdyRef
 
RdyRef = 1; (bit 2)
Now the drive follows the speed or torque references
Note:
To give On and Run at the same time set OnOff1 (10.15) = StartStop (10.16).
