Siemens Robicon power unit
The Siemens Robicon LDZ31500082.660 power unit is a power unit in the Siemens Robicon series, mainly used in high-voltage frequency converters, responsible for converting DC power to AC power and outputting it to the load end. It consists of rectifier bridge, filtering capacitor, IGBT module, etc., which can achieve AC-DC-AC voltage type unidirectional output. By controlling the input voltage frequency and amplitude of the motor, precise control of the motor speed can be achieved

Siemens Robbins' products are widely used in industrial automation, power systems, new energy
generation, and other fields. In industrial automation, Robin Kang's power module can accurately
control the operation of motors, improve production efficiency and product quality; In the power
system, achieving precise control and distribution of electrical energy can improve the stability and
reliability of the power grid; In new energy generation, meeting the requirements for grid connection
and improving the efficiency and stability of new energy generation.
Maintenance and troubleshooting
Confirmation of speed and encoder resolution: Ensure that the speed and encoder resolution
meet the system requirements.
Calculation of load torque: including the conversion of load torque on the motor shaft and the
calculation of acceleration and deceleration torque.
Calculation and selection of regenerative resistors: For systems above 2KW, external configuration
of regenerative resistors is required.
Cable selection: Encoder cables require twisted pair shielding. For Japanese products, encoders
have 6 cores, while incremental encoders have 4 cores.
The selection of braking methods: electromagnetic braking, regenerative braking, and dynamic
braking each have their own advantages and disadvantages, and it is necessary to choose the
appropriate braking method according to the specific application scenario
