Driving power supply module is used for connecting each drive unit and high voltage power supply system, main power transform for the DC voltage on the DC bus. All cooling parts, for example, can be introduced into the air module to reduce the module temperature of the discrete fan or / and heat sink, also included in the module supply range. The width of 200 mm (7.87 in) module, whether internal or external cooling method, the standard components should include cooling components required, such as an independent fan / or a heat conduction cover to air flow through the module cooling. For the size of 300 mm (11.81 in) please comply with the relevant matters needing attention. Shielding terminal board can be provided to meet the electromagnetic compatibility (EMC) of the power cable wiring requirements for the power cable with shielding, shielding connectors should be used in order to achieve the requirements of electromagnetic compatibility. An over voltage limiting module used to meet the IEC requirements of the inverter or grid. When the drive power supply module needs to meet the UL standard, it must use the voltage limiting module. Driving power supply module use 400V / 3 phase AC + 10%, 50 / 60 Hz, 415 V / 3 phase AC + 10% 50 / 60 Hz or 480 V / 3 phase AC + 6% to 10% of the 50 / 60 Hz mains voltage generated DC connection requires the direct driving voltage. In addition, the drive module (by the power module 6SN1123, closed loop control module 6SN1118, composition) provides power supply (+/-24V, +/-15V, 5V, etc.).

If the drive power supply module and to a non - TN form of grid connected or with a without the use of direct current sensitive to residual current protection device of grid connected, we need from the selection list in accordance with Yyn0 vector group selection for an isolation transformer. For regulating type of drive power / regenerative feedback module, if there is a transformer at its entrance, the same need to install high frequency rectifier reactor. Similarly, when the grid voltage is 200 V / 220 V / 240 V / 400 V / 500 V / 575 V / 10% / 50 Hz / 60 Hz, the need to use a suitable transformer to carry out the voltage matching.

Non regulated drive power module

Application range

Rarely - even if the brake braking or braking but the cycle time is very short and very low braking energy machine

In the grid work environment in SKmains: /P nUl = 30 (SK mains: short circuit of the main power supply power: P nUI: UI module power rating)

Dynamic - driven requirements have certain limitations, especially for spindle drive.

The output power of the non regulated drive power supply is relatively low. The maximum power of these modules is 10KW, including a rectifier reactor and a

Pulse resistor for driving module braking energy into heat. If the pulse resistor is used in its maximum capacity (>200W), a heat transfer should be used.

The guiding cover is separated from the heat and not to the module.

For the 28KW non regulated drive power supply module, the rectifier reactor and pulse resistance device must be ordered and installed separately. Non regulated drive power module

Has contained the control of the pulse resistor.
