What is 6SN1123-1AB00-0BA1 and where is it used?
The 6SN1123-1AB00-0BA1 is a SIMODRIVE 611 power module from Siemens in a 2-axis configuration. Siemens classifies the unit as a 25 A power module with internal heat dissipation; the associated motor rated currents are 9 A for feed axes and 8 A for the main spindle. The module is used within SIMODRIVE 611 and SINUMERIK environments, typically in CNC machines, machine tools and other applications where controlled feed and spindle drives must operate reliably. Within the system, the power module works together with the power supply module, control module, motor and encoder system. For maintenance engineers, the exact part number is therefore essential for clearly identifying a defective module and avoiding ordering errors when arranging repair, exchange or replacement.
Important technical data and what it means
The key specifications are directly relevant for selection and installation. The 2-axis design means that the module controls two drives within the SIMODRIVE 611 system. The 25 A rating defines the module’s power class, whilst the associated motor rated currents of 9 A for feed axes and 8 A for the main spindle are important for matching the correct motor. Internal heat dissipation means that the generated heat must be properly considered within the control cabinet design and removed effectively. For procurement purposes, additional reference data is useful: EICHLER lists an EAN of 4025515019527 and a net weight of 6 kg. Other market sources specify approximately 5.5 kg, placing the unit in the category of a compact but installation- and transport-sensitive power module.
Product status, life cycle and obsolescence
For operators of legacy systems, the life-cycle status of this module is particularly important. EICHLER lists the product with an EOP (End of Production) date of 30/09/2010. Siemens also officially discontinued the SIMODRIVE 611 drive system with effect from 31/03/2014. As a result, availability today is no longer comparable to that of an active production product and must instead be managed through repair services, exchange programmes, stock holdings and secure spare-parts channels. One positive aspect is that Siemens provides a documented substitution path. In the Siemens substitution list, 6SN1123-1AB00-0BA1 is superseded by 6SN1123-1AB00-0BA2. The BA2 version is described with the same key specifications: 2-axis power module, 25 A, internal heat dissipation, 9 A feed axis current and 8 A spindle current.
Available EICHLER services for 6SN1123-1AB00-0BA1
EICHLER offers repair, exchange, refurbished units and new units on request for this module. In the event of an unexpected machine failure, an exchange unit or a tested refurbished module is usually the fastest solution, with EICHLER indicating a delivery time of 1–3 days. If the original module is to be retained or the machine is particularly sensitive to hardware variations, repair is often the preferred option, with a typical turnaround time of 7–10 days. According to EICHLER, the repair service includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. A SIMODRIVE LT inverter test report is also available. This is particularly valuable when maintenance, purchasing and quality assurance departments require documented proof of functionality and release for operation.
| Fault description | Possible solution |
|---|---|
| Why does my SINUMERIK report alarm 300101 “Bus start-up failed” with 6SN1123-1AB00-0BA1? | This alarm indicates that the NC is already running but the first drive module has not been detected. First check whether the first module is actually receiving power and whether the LED indicators respond plausibly. Then inspect the ribbon cable between the E/R unit or monitoring module and the first drive module, verify connector seating and check the power supply. Where separate power supplies are used, the NCU and drives should be switched on as simultaneously as possible. Afterwards, switch the system off completely, restart it and acknowledge the alarm with a RESET. |
| Why does SIMODRIVE 611 report alarm 300500 with error code 0012H or 0013H? | These error codes indicate problems within the NC basic clock cycle or disturbances on the drive bus. Check the drive bus cable, all connectors, as well as shielding and earthing connections. If the fault occurs only intermittently, the EMC environment should also be examined. If the error remains after cable and EMC checks, the NC hardware or control module may be responsible. After correcting the issue, perform a complete system restart and review the diagnostics again. |
| Why does alarm 300500 with error code 0022H appear on an axis? | Siemens describes this error as a missing or defective PCU ASIC for the motor measuring system, or as a communication fault on the drive bus. Check the encoder connection, connectors, communication path, shielding and earthing. If the measuring system is mechanically and electrically connected correctly and the fault persists, the control module or motor measuring system should be specifically tested or replaced. |
| Why does the drive fail to start and alarm 300500 display error code 0046H or 0050H? | Error code 0046H indicates that the drive start-up sequence was aborted because the correct software version was not loaded. The appropriate drive software must therefore be reloaded. Error code 0050H additionally indicates that the installed module and the loaded drive software are not compatible. In this case, either the correct software must be loaded for the installed module or the appropriate module must be fitted before attempting the start-up sequence again. |
Is 6SN1123-1AB00-0BA1 still available or has it been discontinued?
From a life-cycle perspective, the module is obsolete. EICHLER lists an EOP (End of Production) date of 30 September 2010, and Siemens discontinued the SIMODRIVE 611 drive system with effect from 31 March 2014. For operators, this does not automatically mean that replacements are no longer available. However, supply is now typically maintained through repair services, exchange units, tested refurbished modules and remaining stock, rather than through normal series production as with active product lines.
Is 6SN1123-1AB00-0BA2 a compatible successor?
Yes. Siemens identifies 6SN1123-1AB00-0BA2 as the substitution for 6SN1123-1AB00-0BA1. Siemens also specifies the BA2 version with the same key characteristics: 2 axes, 25 A, internal heat dissipation, 9 A feed-axis motor current and 8 A main spindle motor current. Before final approval, the complete machine environment should still be checked, including drive parameters, axis configuration, software version and the thermal design of the control cabinet. In existing machines, this detailed verification determines whether a nominally compatible successor can be used without introducing additional risks.
Should I repair or replace the module in the event of machine downtime?
If downtime is the primary concern, replacement is usually the better option, as EICHLER specifies a delivery time of 1–3 days. Repair becomes more attractive when the original module should remain in the system or when you wish to have the existing unit professionally refurbished and returned with documented test results; EICHLER specifies 7–10 days for this service. According to EICHLER, the repair process includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. In practical terms, replacement minimises downtime, while repair helps preserve asset value and long-term spare-parts availability.
Can I still buy 6SN1123-1AB00-0BA1 as a new part?
New units are no longer readily available through standard supply channels. EICHLER lists new condition only as an enquiry item, while some market sources occasionally offer new or sealed remaining stock. For an EOP product, such availability usually comes from surplus inventory or secondary-market suppliers rather than from active manufacturer stock. For many companies, refurbished modules or exchange units are therefore the more realistic and predictable option, especially when delivery time, testability and documented functionality are more important than obtaining an unused part.
Why is a test report useful for this module?
A test report is particularly valuable when the technical release of a repaired or replacement module needs to be documented internally. EICHLER specifically offers a SIMODRIVE LT inverter test report as an option for this module. This provides maintenance, purchasing and quality departments with reliable evidence of the module’s tested condition. For obsolete CNC drive components in particular, a documented test status helps reduce disputes during recommissioning, shift handovers, audits or any later warranty and complaint assessments.
