Product Introduction
SDCS-CON-4 3ADT313900R1501 board is equipped with FlashPROM, which contains the firmware plus the stored parameters. Parameters handled by the DCS800 panel or DWL, PCtool, or by the Serial communication parameter service are stored immediately in the FlashPROM. Parameters handled by cyclic serial communication (dataset table Group 90 - 92) are not stored in the Flash PROM. They must be stored by means of ParApplSave (16.6) service. The faultlogger entries are stored in the FlashPROM during power down (auxiliary power supply OFF).

Product Details
The control board SDCS-CON-4 3ADT313900R1501 has an internal watchdog. The watchdog controls the running of the control board program. If the watchdog trips, it has the following effects:
• Writing to FPROM is disabled.
• Thyristor firing control is reset and disabled.
• Digital outputs are forced low.
• Programmable analogue outputs are reset to zero, 0V.
Seven-segment display:
A seven-segment display is located on the control board SDCS-CON-4, and it shows the state of the drive.
Terminal description:
X37: Connector is used for the supply of SDCS-CON-4 from SDCS-POW-1, SDCS-POW-4, and SDCS-PIN-4 supply voltage can be measured to ground. X37:3= 48V
X37:5=24V
X37:7=15V
X37:11=-15V
X37:13=5V encoder
X37:23=5V CPU
Supply voltage monitoring CPU is monitored by 4.75 V and forces the CPU to reset. In parallel, the CPU monitors the Powerfail signal from the power supply (SDCS-PIN-4 or SDCS-POW-1).
Connecting a pulse encoder to the DCS800 converter:
The connection diagram for a pulse encoder to the electronics of a DCS converter is quite similar if the SDCS-CON-4 or the SDCS-IOB-3 is used. The basic difference between these 2 boards is the galvanically isolated circuit and pulse receivers via a pto coupler on the SDCS-IOB-3 board.
Power supply for the incremental encoder: The
SDCS-CON-4 and SDCS-IOB-3 boards have jumpers to select a supply voltage. V17 LED on SDCS-IOB-3 indicates supply is OK.
