GE DS200LDCCH1ANA Drive Control CPU Board

Configured for executing motor control algorithms and SCR firing angle calculations in GE Mark IV LCI systems, the GE DS200LDCCH1ANA (DS200LDCC Drive Control CPU Board) provides direct physical/electrical execution. This module coordinates drive control functions and executes real-time fault detection logic without relying on external supervisor units.

Brand-Specific Technical Features

The DS200LDCCH1ANA interfaces directly through the proprietary QDII backplane bus communication structure to manage high-speed motor control data exchanges. Firmware flash compatibility and onboard NVRAM maintain deterministic execution loops for SCR firing angles, eliminating communication delays across the backplane bus interface.

Frequently Asked Questions

Q: What is the purpose of the onboard 3.6 V lithium battery?

A: The onboard battery provides backup power to the NVRAM, ensuring that calibrated drive parameters and diagnostic fault logs remain intact during system power shutdowns.

Q: Can the DS200LDCCH1ANA be hot-swapped while the LCI system is operational?

A: No. Power to the rack must be completely isolated before removing or inserting the board to prevent backplane bus disturbance and potential damage to onboard semiconductors.

Field Installation Guidelines

1. Power down the drive cabinet and verify zero-voltage state on the 24 VDC supply before board handling.
2. Wear a grounded wrist strap connected to the enclosure frame to prevent electrostatic discharge damage.
3. Align the board edges with the Mark IV card guide slots and slide in until the rear edge connectors seat into the QDII bus backplane.
4. Tighten the retaining screws on the front panel to ensure solid chassis grounding and mechanical stability.
