The GE Drive Control/LAN Communications Board DS200LDCCH1ANA features multiple microprocessors that provide control for the drive, motor, and I/O functions. It also provides control for the LAN network. The GE Drive Control/LAN Communications Board DS200LDCCH1ANA is populated with four microprocessors and each microprocessor is assigned a separate function.

One microprocessor provides drive control processing. One microprocessor provides motor control processing. One microprocessor provides co-motor processing. And one microprocessor provides LAN control processing.

If the board is not functioning properly or seems to be providing less than optimal performance, you might want to perform a soft reset on the board. A hard reset is when electric power is interrupted and the board must restart. When possible, this should be avoided and it should only occur if the drive malfunctions or a trip condition occurs that causes the drive to shutdown unexpectedly. For example, if an overload condition occurs the drive will automatically shutdown to protect the components and the motor.

The better option to restart the board is a soft reset. This is when power remains present in the board and is used to clear faults. One method of performing a reset is to press the Reset button on the board. Only a qualified individual should do this because power is present in the drive and there is a risk for electric shock or burn. It requires the servicer to reach into the board cabinet and press the Reset button. Press the button for about 5 seconds, then release the button.

The DS200LDCCH1ANA is a LAN communications circuit board developed by General Electric. It is used in GE EX2000 Excitation and DC2000 product lines and is an advanced 7-layer circuit board that is essentially the brains of the EX2000 and DC2000. The primary functions provided by the board include operator interface, LAN communications, drive and motor processing and drive resets. It includes several onboard features including a microprocessor controlled LAN (local area networks) communications, controlled drive and motor processing, operator interface and complete drive resets. There are four microprocessors on the board, providing it with a sweeping coverage of I/O and drive control.

The drive control processor is located on the board as position U1 and it provides integrated I/O peripherals, offering abilities like timers and decoders. The second is a motor control processor recognized on the board as U21. Motor control circuitry and I/O (analog and digital) communications are available with this processor. U35 is the location of the co-motor processor. Only used when additional processing is required, this section works to perform advanced mathematics the MCP cannot compute.

The final processor found on the board is the LAN control processor in position U18. Five bus systems (DLAN+, DLAN, Genius, CPL, and C-bus) are accepted by this processor. A user interface system is available with an attached alphanumeric keypad allowing users to view and adjust system settings and diagnostics.
