What is 6SN1145-1BA02-0CA2 and where is it used?
6SN1145-1BA02-0CA2 is a SIEMENS SIMODRIVE 611 infeed/regenerative feedback module. Siemens lists the assembly as a spare part and describes it as a controlled module with 36/47 kW, internal heat dissipation, and a line contactor with normally closed contact. Within a SIMODRIVE 611 drive system, the module is responsible for supplying the drive group from the mains and feeding braking energy back into the power supply. This is particularly relevant in machine tools, CNC systems, machining centres, and machines with dynamic feed or spindle drives where a stable DC-link supply and controlled energy regeneration are important. For maintenance personnel, the module is often a critical spare part when downtime must be minimised and existing systems need to remain operational.
Overview of the most important technical data and what it means
The key specifications are particularly useful for identification, compatibility checks, and control cabinet planning. Siemens specifies 6SN1145-1BA02-0CA2 as a 36/47 kW module with a net weight of 14.0 kg, country of origin Germany, and customs tariff number 85044095. Within the SIMODRIVE 611 environment, the system operates with a nominal DC-link voltage of 600 V; the electronics shut down below 350 V. For the 36 kW infeed/regenerative module size, the configuration manual also specifies a module width of 200 mm and a replaceable fan. For purchasing and engineering teams, this means that the module is identified not only by its part number but also by its power rating, mechanical design, and electrical integration within the existing drive system.
Product status, life-cycle status, and obsolescence
From a procurement perspective, the status is clear: Siemens lists 6SN1145-1BA02-0CA2 as a spare part with PLM status PM410 Product Cancellation, effective from 01/04/2015. The EICHLER product page also shows the status EOP: 2015-04-01. Siemens additionally identifies the product as non-RoHS compliant. This makes it clear that the module should already be considered part of an active obsolescence and spare-parts management strategy in many facilities. No currently marketed direct successor could be verified in the available Siemens documentation. However, Siemens does document a substitution from 6SN1145-1BA02-0CA1 to 6SN1145-1BA02-0CA2 due to a component change. For existing installations, precise MLFB verification therefore remains particularly important.
Available EICHLER services and when they are relevant in practice
For operators of older SIMODRIVE 611 systems, several service options are important. EICHLER offers repair for this module with a turnaround time of 7–10 days, including technical cleaning, preventive maintenance, comprehensive functional testing, and a minimum 24-month warranty. Exchange units and used units are both available with a lead time of 1–3 days, and an optional load test for infeed/regenerative modules is also offered. New units are available on request. Repair is particularly attractive when the existing module is to remain in service. For purchasing and production departments, an exchange unit is usually the better option when downtime costs exceed the additional procurement cost. The load test is especially valuable when faults occur only under real operating loads or during regenerative operation.
| Fault description | Possible solution |
|---|---|
| Why does the SIMODRIVE 611 infeed/regenerative module report “Infeed module not ready for operation”? | First check the module enable chain. Siemens identifies missing enable signals at terminal 63, 64 or 48 as a typical cause. In addition, FR+ / FR-, the reset signal at terminal R/19, DC-link precharging and the PLC-side ready-for-operation logic should be checked. The 111–213 feedback contact of the internal line contactor and the status of the LEDs are also relevant. If the ready signal remains absent although the supply voltage is present, the line contactor, wiring and enable signals should be checked systematically. |
| Why does the infeed/regenerative module indicate “DC-link overvoltage”? | Siemens lists several possible causes: regenerative operation disabled, setup mode, mains fault, excessive mains voltage, dynamic overload or an incorrectly installed line filter between the infeed/regenerative module and the commutating reactor. If a mains fault is displayed at the same time or the yellow LED is not illuminated, the overvoltage limiting module should also be checked. Siemens describes a functional test by disconnecting the module and connecting X181 directly to the infeed module. If the module then operates correctly, the overvoltage limiting module should be replaced. |
| Why does the ready status drop out or why does the fault message appear immediately after power-up? | According to Siemens, the cause may be a faulty electronics power supply, an incorrect 5 V supply level, problems with the mains connection, the equipment bus or the DC-link connection. During troubleshooting, not only the power connections but also the auxiliary supply and plug connections should be checked. The module LEDs help with fault isolation, distinguishing between conditions such as “Device ready”, “DC-link overvoltage” and “Electronics power supply fault”. If start-up problems occur repeatedly, it should also be verified that the precharging sequence is completed correctly. |
| Why does the module no longer regenerate braking energy even though the axes initially continue running? | Siemens describes this behaviour when LED 5 is illuminated red. In this condition, pulse suppression is active only for the infeed/regenerative module, meaning regenerative operation is no longer possible, although the axes may continue running temporarily and the ready relay drops out. In this case, overload conditions, mains faults, overvoltage events and the module enable conditions should be checked. If the fault repeatedly occurs under load, a comprehensive functional test or replacement is often the quickest way to prevent consequential damage within the drive system. |
Is 6SN1145-1BA02-0CA2 still an active Siemens product?
No. Siemens lists the module as a spare part and classifies it with PLM PM410 Product Cancellation. The effective date is 01/04/2015. For operators, this means the module should no longer be considered a current production product but rather part of an obsolescence management, spare-parts stocking, repair, and exchange strategy.
Which information should I provide when requesting a quotation, placing an order, or submitting a repair request?
For fast identification, the most important details are the complete MLFB 6SN1145-1BA02-0CA2, the EAN 4019169393379, the EICHLER article number K0202623, and the module type SIMODRIVE 611 infeed/regenerative module. It is also helpful to provide the fault description, LED status, machine or system type, and information on whether the fault occurs only under load or already during power-up. This significantly reduces the risk of confusion with similar SIMODRIVE 611 infeed/regenerative modules.
Can 6SN1145-1BA02-0CA2 still be obtained at short notice?
Yes. Short-term procurement is generally realistic through the secondary market and specialist service providers. According to the EICHLER product page, exchange units and used units are available with a lead time of 1–3 days, while repair is typically specified as 7–10 days. Market listings for this MLFB also show that other suppliers continue to offer stock or refurbished units. For critical applications, the decisive factor is often not only the price but also the available delivery model.
When is repair more sensible than exchange?
Repair is usually the better option when the existing module has been clearly identified, immediate recommissioning within 24 to 72 hours is not required, and retaining the original unit is preferred. Exchange is generally the better solution when production downtime is costly and a tested replacement unit is needed as quickly as possible. This distinction is clearly reflected in the EICHLER service offering: repair requires more time, whereas exchange is available significantly faster.
Is there a Siemens-designated direct successor for 6SN1145-1BA02-0CA2?
A currently designated direct successor from Siemens could not be verified in the available manufacturer documentation. However, a substitution within the same module family is documented: Siemens specifies the change from 6SN1145-1BA02-0CA1 to 6SN1145-1BA02-0CA2 due to a component modification. For spare-parts procurement, this distinction is important because a substitution is not automatically the same as a modern successor product.
Is the module RoHS compliant?
According to Siemens product data, 6SN1145-1BA02-0CA2 is not RoHS compliant. This information is particularly relevant for international procurement, life-cycle management documentation, and internal compliance reviews. For retrofit projects, export applications, or audit-related activities, this point should therefore be clarified at an early stage.
