What is 6SN1145-1BA02-0CA1 and where is it used?
The 6SN1145-1BA02-0CA1 is a SIEMENS SIMODRIVE 611 power supply/regenerative module. Siemens describes it as a regulated 36/47 kW module with internal cooling and a mains contactor with normally closed auxiliary contact. Within the drive system, the module is responsible for supplying power to the DC link and feeding regenerative braking energy back into the mains supply. It is used in SIMODRIVE 611 configurations where multiple drive modules are connected to a common DC link. Typical applications include CNC machines and industrial production systems where system availability, stable DC-link voltage and reliable control cabinet integration are critical. For maintenance and purchasing departments, the exact article number is especially important because power rating, cooling concept and installation conditions must match the existing system precisely.
Overview of the key technical data and what they mean
The 36/47 kW rating identifies the module size within the SIMODRIVE 611 regulated power supply/regenerative module family. Siemens documentation lists the 36 kW I/R module with a module width of 200 mm. For the internally cooled version, Siemens specifies a weight of approximately 15.5 kg, a rated current of 60.5 A at 400 V, and power losses of approximately 585 W. The EICHLER product page lists a net weight of 16 kg. In practice, this means that the module requires sufficient control cabinet space, adequate cooling and a correctly dimensioned power supply. The mains supply is adapted to local network conditions via selector switch settings; Siemens specifies settings for 400 V, 415 V and 480 V systems, as well as operation on grounded TN systems.
Product status, life-cycle status and obsolescence
For 6SN1145-1BA02-0CA1, the EICHLER product page lists an EOP (End of Production) date of 09 May 2007. Siemens also documents an official substitution due to a component modification: old part number 6SN1145-1BA02-0CA1, new part number 6SN1145-1BA02-0CA2. At system level, Siemens removed SIMODRIVE 611 from active marketing as of 01 April 2014 and transferred it to lifecycle status PM410 / Type Discontinuation from 01 April 2015 onward. For operators, this means that long-term support is now typically achieved through spare-part sourcing, exchange units, used equipment and repair strategies. Where migration to a newer platform is not immediately possible, maintaining tested spare inventory and working with a qualified service partner becomes essential for minimising unplanned downtime.
Available EICHLER services and when they are relevant
EICHLER offers several practical service and procurement options for this module. Repair is particularly attractive when the existing module is fundamentally repairable and the original installation should remain unchanged; the stated turnaround time is 7–10 days. According to EICHLER, the repair process includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. Exchange service is especially valuable in the event of critical downtime, with an indicated lead time of 1–3 days. In addition, tested used units are available with 1–3 day delivery times, while new units are offered on request. The optional load test for power supply/regenerative modules is particularly relevant when the module must be validated under realistic operating conditions and when an extended warranty is required.
| Fault description | Possible solution |
|---|---|
| Why is my SIMODRIVE 611 regenerative power supply module not ready for operation? | If the module is not ready for operation, first check the enable signals at T.63, T.64 and T.48, the electronics power supply and the contactor control circuit. Siemens explicitly associates this condition with missing enable signals. During commissioning, an incomplete or inconsistent parameterisation or an incorrect archive can produce the same effect. Therefore, it is advisable to verify the power supply, enable chain and project status before prematurely replacing the module. |
| Why does my SIMODRIVE 611 report DC-link overvoltage? | A common cause is regenerative energy flowing back into the DC link during braking while the regenerative function is disabled or ineffective. In the SPS forum, particular attention is drawn to the S1.3 switch position: if line regeneration is disabled, DC-link overvoltage can occur during deceleration. Siemens also identifies mains supplies that do not reliably meet the required planning conditions as an application for an overvoltage limiting module. Therefore, check the regenerative function, mains quality, braking profiles and, where applicable, the overvoltage limiting module. |
| Why does the 6SN1145-1BA02-0CA1 not provide 600 V DC in the DC link? | Siemens support information recommends a step-by-step approach when DC-link voltage is missing: switch the axes on individually, check motors and power cables for insulation faults and observe the behaviour of the regenerative module with no connected load. In addition, the chain line filter > choke > I/R module and the wiring of pulse enable, drive enable and contactor enable should be checked. Only when these points have been verified should the fault be attributed primarily to the power supply/regenerative module itself. |
| Why do SIMODRIVE 611 power supply modules fail repeatedly? | Siemens has specifically pointed out that increased failure rates can occur in I/R modules when third-party line chokes are used. In addition, Siemens requires a grounded TN system or a suitable transformer with an appropriate secondary side when other network configurations are present. In the event of recurring failures, not only the module and cooling fan should be checked, but also the line choke, filter, mains configuration and grounding system. |
| Why does the module indicate a 5 V fault or an electronics power supply fault? | In the LED descriptions for the power supply module, Siemens separately identifies “5V voltage level faulty” and “power supply electronics faulty” conditions. If these indications occur, first check the external electronics power supply, then inspect connectors, internal supply circuits and the module electronics. If the fault persists, repair is usually more effective than simply restarting the unit, as the root cause is often located in the module's internal power supply electronics. |
Is the 6SN1145-1BA02-0CA1 still available or has it been discontinued?
The 6SN1145-1BA02-0CA1 is clearly positioned in the obsolescence phase of its lifecycle. The EICHLER product page lists an EOP (End of Production) date of 09 May 2007. Siemens also announced that the SIMODRIVE 611 platform was withdrawn from active marketing on 01 April 2014 and entered Type Discontinuation status on 01 April 2015. For purchasing departments, this does not automatically mean that the module is unavailable; however, procurement today is typically handled through spare-parts channels, exchange units, used stock or repair services rather than through regular series production.
Is the 6SN1145-1BA02-0CA2 a compatible successor to the 6SN1145-1BA02-0CA1?
Yes. Siemens officially documents a part-number change due to a component modification: old part number 6SN1145-1BA02-0CA1, new part number 6SN1145-1BA02-0CA2. This makes the 6SN1145-1BA02-0CA2 the manufacturer-designated successor. This is particularly important when the original part number is no longer readily available. Nevertheless, before replacement, the installation conditions, existing peripherals and the specific machine project should be reviewed to ensure that the substitution is implemented correctly within the existing system.
What does the 36/47 kW rating mean for this module?
The rating identifies the power class of the regulated power supply/regenerative module within the SIMODRIVE 611 range. Siemens classifies the unit as a 36/47 kW module; technical data for the 36 kW regenerative power supply size include a 200 mm module width, 60.5 A rated current at 400 V and the corresponding internal cooling characteristics. In practice, this figure is not merely a marketing specification—it is directly relevant to system sizing, mains connection requirements, cooling, installation space and compatibility with the existing drive group. When sourcing a replacement, it is therefore essential to search using the complete article number rather than simply looking for a “SIMODRIVE 611 regenerative module”.
When is repair preferable to exchange or purchasing a replacement?
Repair is particularly worthwhile when the original module should remain in the control cabinet, the unit is fundamentally repairable and no design changes to the machine are desired. Exchange service is generally the best option during an acute production outage, as EICHLER specifies a delivery time of 1–3 days and indicates the availability of multiple units. Purchasing a new unit may be appropriate when a like-new condition is required for audits, acceptance procedures or long-term lifecycle planning, although it is typically the most expensive option. For operators of older systems, the most economical solution is often a combination of rapid exchange to minimise downtime followed by repair of the original unit for future spare stock.
Which mains conditions are important for this module?
Siemens describes the power supply modules as adaptable to different mains conditions using the selector switches S1.1 and S1.4. Depending on the setting, the module supports 400 V, 415 V and 480 V mains systems. The system is designed for grounded TN networks; for other network configurations, Siemens recommends using an upstream transformer with a suitable secondary side. For maintenance and retrofit projects, this is particularly important because incorrectly set mains switches or unsuitable network configurations can lead to unstable operation, fault messages or premature module failure.
What is the benefit of the optional load test for a regenerative module?
The optional load test offered by EICHLER is particularly valuable when not only basic electrical functionality but also performance under realistic operating conditions must be verified. This is especially relevant for power supply and regenerative modules because they directly influence DC-link stability, regenerative energy handling and overall system availability. For both purchasing and engineering departments, a documented load test reduces the risk of installing a module that appears functional during basic testing but becomes unstable under actual operating loads in a critical production environment.
