Product Introduction

Siemens Power Board C98043-A7001-L2 is a control board for DC motor speed regulation. It has multiple functions and is suitable for various application scenarios in industrial automation. Here are some of the main functions of the board:
DC Motor Speed ​​Regulation
C98043-A7001-L2 can adjust the speed of DC motors by changing the armature voltage, the excitation winding voltage or the armature circuit resistance. Among them, the most commonly used method is the voltage regulation speed regulation system, that is, the motor speed is adjusted by controlling the armature DC voltage.

Integrated design
The speed regulator is small in size and light in weight. It can be used alone or directly installed on the DC motor to form an integrated DC speed regulation motor with all the functions that a speed regulator should have.

Digital control
With the development of computer technology, analog control systems are gradually replaced by digital control systems. C98043-A7001-L2 is a fully digital DC speed regulation device. With software support, various regulation and control functions can be easily realized without changing the hardware or with only a small amount of modification, which improves the reliability and application flexibility of the system.

Real-time monitoring and diagnosis
The board can monitor the running status of the motor in real time, including parameters such as armature incoming line voltage, excitation incoming line voltage, actual incoming line frequency, etc., and can be clearly displayed on the display screen, which is convenient for operators to observe and adjust1. In addition, it also has a fault diagnosis function, which can detect and report abnormal conditions in the system.

Communication and programming
C98043-A7001-L2 supports configuration and remote programming services through industrial Ethernet, such as uploading and downloading programs, monitoring status, etc. This makes system maintenance and upgrades more convenient.

Working principle
The DC speed regulator is a device that adjusts the speed of a DC motor. Its working principle is as follows:
Connection method: The upper end is connected to the AC power supply and the lower end is connected to the DC motor.
Voltage conversion: Convert AC power into two output DC power supplies, one for the motor armature (rotor) and the other for the excitation stator.
Speed ​​regulation: The speed of the DC motor is adjusted by controlling the armature DC voltage.
Feedback control: The motor speed is judged according to the feedback current, and the armature voltage output is corrected if necessary to adjust the motor speed.
