Siemens power module
- Single axis or dual axis power modules with a wide power range can be used. These modules are classified by current amperage and can provide three different cooling methods. The rated current parameters are related to a series of pre-set parameter values. For higher operating frequencies or pulse frequencies, appropriate reductions should be made (see design guidelines), and accordingly, pre assembled power cables for connecting various motors can also be ordered. Please refer to the section on motors to determine the ordering parameters. In order to meet the requirements of electromagnetic compatibility (EMC) standards, it is necessary to connect a shielded terminal board to the shielded power cable. The driver unit bus cable is included in the power module component and is a part of it. For digital systems, the driver bus cable must be ordered separately.

The drive power module is used to connect various drive units and the high-voltage power supply system, converting the main power supply into DC voltage on the DC bus. All cooling components, such as discrete fans and/or heat dissipation plates that can introduce air into the module to reduce its temperature, are also included in the supply scope of the module. For modules with a width of 200mm (7.87in), whether using internal or external cooling methods, the standard components should include the required cooling components, such as an independent fan/or heat conduction cover to cool the module through air flow. Please follow the relevant precautions for dimensions of 300mm (11.81in).
Shielded terminal boards can be provided to meet the wiring requirements for electromagnetic compatibility (EMC) of power cables. For shielded power cables, shielded connectors should be used to meet EMC requirements. The overvoltage limiting module is used for inverters or power grids that cannot meet IEC requirements. When the driving power module needs to meet UL standards, an overvoltage limiting module must be used.
The driving power module uses a main power supply voltage of 400V/3-phase AC ± 10%, 50/60Hz, 415V/3-phase AC ± 10% 50/60Hz, or 480V/3-phase AC+6% to -10% 50/60Hz to generate the direct driving voltage required for DC connection. In addition, power supply (+/-24V,+/-15V,+5V, etc.) is provided to the drive module (consisting of power module 6SN1123 and closed-loop control insertion module 6SN1118) through the device bus. If the driving power module is connected to a non TN grid or to a grid that does not use direct current sensitive residual current protection devices, an isolation transformer needs to be selected from the selection table according to the Yyn0 vector group. For regulating drive power/regenerative feedback modules, if there is a transformer at its inlet, a high-frequency rectifier reactor also needs to be installed. Similarly, when the grid voltage is 200V/220V/240V/400V/500V/575V ± 10% 50Hz/60Hz, a suitable transformer is required for voltage matching.
Non regulating drive power module
Application scope
Machine tools that rarely brake or even brake but have a short braking cycle time and low braking energy
The working environment of the power grid is: SKmains/PnUl ≥ 30 (SK mains: main power short-circuit power: P nUI: UI module rated power)
The dynamic requirements of the drive have certain limitations, especially for the spindle drive.
The output power of non regulated driving power modules is relatively low. The maximum power of these modules is 10KW, including a rectifier reactor and a pulse resistor that can convert the braking energy of the drive module into heat. If the pulse resistor uses its maximum capacity (>200W), a heat conduction cover should be used to separate the heat from the module above.
For a 28KW non regulating drive power module, rectifier reactors and pulse resistors must be ordered and installed separately. The non regulating drive power module already includes control of the pulse resistor.
Additional functions of non regulating drive power module
Power rectifier for DC connection bus voltage
Use coded switches to control the following optional pulse resistors
1. Built in pulse resistor
2. Connect to the 28KW module using an external pulse resistor
Adjustable drive power supply/regenerative feedback module
Application scope
Machine tools with high dynamic requirements for drive devices
Frequent braking cycles and high braking energy
To reduce operating costs, the control cabinet needs to be optimized by using a regulating drive power supply/regenerative feedback module, which may re feed the excess energy generated by the DC connection coil. For example, braking can be applied
The generated energy is re inputted into the power grid system. This can optimize the cooling effect of the electrical switchgear, while also reducing energy consumption costs for the staff.
The adjustable drive power module allows each drive shaft to operate at a constant DC connection voltage.
It is necessary to use the matching high-frequency rectifier reactor listed in the selection table to connect to the main power supply equipment. To ensure compliance with the electromagnetic compatibility requirements of the European Community, it is necessary to use the corresponding main power filter.
Additional functions of regulating drive power module/regenerative feedback module
For adjustable drive power modules, cooling switches can be used to select different operating functions
Adjust the input of the power grid with a connection voltage of 600V DC or 625V DC, sinusoidal current load, and power factor COS λ>=0.97. The power factor takes into account the sum of all resonant voltages in the power grid.
Modulation operation is performed on the grid input of square wave current load when the connection voltage is 600V DC or 625V DC.
Perform non regulated operation on the grid input with or without regenerative feedback when the connection voltage is 490V DC (400V 3-phase AC).
Direct operation of TN power grid with 480V3 phase AC+6% -10%: equipped with regenerative feedback function and non modulated connection voltage of 680V, frequency of 50HZ/60HZ.
