SIEB & MEYER Powermodul 26.50.65

Module Feature

SIEB & MEYER Powermodul 26.50.65 is a high-power digital servo power module. It adopts IGBT power topology, works with matching axis control boards to realize three-phase servo motor driving. Supports position, speed and torque control modes. Built-in comprehensive protection functions including overvoltage, undervoltage, overcurrent, short circuit, overheat and motor overload protection. Rack-mounted compact design, excellent EMC anti-interference performance. Widely used in CNC machine tools, semiconductor automation and high-precision production line multi-axis motion control systems.

Working principle

The module converts the input AC mains power into DC bus voltage. According to the control signals sent by the upper controller board, the IGBT power unit outputs variable-frequency three-phase AC power to drive the servo motor. It collects current and temperature signals in real time and performs closed-loop adjustment. Once any fault condition is detected, the module will immediately block power output and send fault alarm signal to protect the whole drive system and mechanical equipment.

Onboard components

IGBT power stack, DC bus capacitor bank, current sampling sensors, gate drive circuit, temperature detection sensor, fault logic circuit, power terminal block, status interface connector.

LED indicators
