Product description

Siemens 6FC5357-0BA32-0AE0 is a central NCU module for the SINUMERIK 840D powerline platform, providing NC and PLC processing in machine tools and retrofit projects using SIMODRIVE 611 digital. Official Siemens documentation assigns the module to the NCU-57x family as an MMC103NCU or NCU 573.2. It supports up to 5 axes and 8 spindles. Documented memory includes 32 MB DRAM, 2.0 MB PCMCIA and 4 MB Flash EPROM. NC user memory is 1.5 MB, while PLC user memory is 64 KB and can be expanded to 192 KB. This configuration makes the module relevant to installed 840D powerline systems whose existing machine software and drive architecture are to remain in service without a platform migration. Siemens specifies control-cabinet installation and recommends 100 mm of clearance above and below the drive unit for air circulation. Siemens 6FC5357-0BA32-0AE0 is offered as a used spare part for maintenance and same-platform replacement in established SINUMERIK-840D infrastructure. Before installation, compare the complete order number, Version B, memory configuration, machine data, PLC and NC backups, software release, drive bus and hardware environment. The unit relies on air cooling and natural circulation, so the documented cabinet clearance must be maintained during installation. The complete Siemens 6FC5357-0BA32-0AE0 identification remains decisive for same-platform replacement.

Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
