Process speed command and feedback signal from regulator card.

Generate PWM trigger pulse for drive power thyristor.

Realize current loop and speed loop compound control.

Implement drive fault detection,over-current and over-voltage protection.

Output fault alarm signal when abnormal operating condition occurs.

Installation

Power off the whole drive cabinet and cut main power supply.

Insert 0-49025 board into designated Cardpak slot.

Fasten front panel fixing screws.

Connect edge connector and terminal wiring according to PCB marking.

Check wiring terminal tightness.

Power on system,set drive parameters and perform commissioning.

Test motor running and verify protection function.

Interface

Cardpak edge connector,screw terminal strip,fault status LED indicators.

Feature

RELIANCE 0-49025,Cardpak series DC drive main control PCB assembly.

Integrated thyristor firing circuit and multi-loop control logic.

Built-in hardware protection circuit against over-current,overvoltage.

Clear terminal marking for convenient field troubleshooting.

Discontinued obsolete board,supply only for old drive equipment spare replacement.

Suitable for metallurgy,paper-making and heavy-duty DC drive renovation.

Diagnostic

Drive cannot start:check board power supply and edge connector contact;

Motor speed out of control:trigger circuit damage or parameter drift;

Drive frequently trips:protection circuit activation,check overcurrent fault;

No pulse output:main board circuit component aging.
