Siemens C98043‑A1047‑L1 Drive Control Board Unit

Module Feature

C98043‑A1047‑L1 is Siemens SIMOREG series DC speed regulator control board. It is the core control component of the early DC drive unit, responsible for current loop and speed loop closed‑loop calculation. It matches the power thyristor board, widely used for traditional DC motor speed regulation in industrial equipment.

Working principle

The board receives speed setpoint and motor feedback signal. Internal circuit calculates trigger angle for thyristor, adjusts DC output voltage to control motor speed, realizes closed‑loop regulation.

Onboard components

Control logic circuit, trigger pulse generating unit, signal acquisition circuit, terminal connector, status indicator, PCB substrate.

LED indicators

Onboard LEDs display power, running and fault status.

Hardware self‑diagnosis

Detect signal loss, trigger pulse abnormality, measure feedback signal, judge hardware fault through drive fault code.

Programming software

Parameter setting through drive panel or matching SIMOREG commissioning tool.
