Characteristics of servo control card repair:
Repair of the servo control card at Neethsel HK involves a comprehensive failure analysis, identification of problems in the circuitry and replacement of damaged electronic components. The process begins with the disassembly of the card, which allows a detailed check of the condition of its components, such as integrated circuits, capacitors, transistors or resistors. If damage to power or communication circuits is detected, the relevant components are replaced with new ones that meet quality standards. Servo control card repair also includes special attention to the regeneration of control circuits and components responsible for input and output signals.
We conduct detailed functional tests of control cards:
Repair of the servo control card at Neethsel HK concludes with functional testing on specially prepared test stands. These test benches are designed to simulate the actual operating conditions of the devices so that their performance and functions can be thoroughly checked. Tests include verifying communication with the drive, controlling the response to control signals, and monitoring the stability of operation over various operating ranges. In addition, each control board is tested for safety compliance and energy efficiency.
Servo control cards are used in many industries, including:
