Description
Additional information

The Siemens SIMODRIVE 610 series is a modular AC servo drive system designed for high-performance motion control applications. The 6SC6100-0NA21 is a power supply module within the SIMODRIVE 610 family, providing regulated DC bus voltage to connected axis modules. This unit belongs to Siemens' established SIMODRIVE 610 platform, which was widely deployed across CNC machine tool and industrial automation environments.

The 6SC6100-0NA21 power supply module features a regulated DC link bus output, enabling multiple axis drive modules to be powered from a single supply unit within a modular drive cabinet configuration. The module incorporates regenerative feedback capability, allowing braking energy to be returned to the AC supply network, improving overall system energy efficiency. It is designed to interface with the SIMODRIVE 610 axis modules via a shared DC bus, and includes monitoring functions for overvoltage, undervoltage, and overcurrent conditions on the DC link. The unit is built to industrial standards with robust thermal management suited for continuous duty operation.

The SIMODRIVE 610 power supply module is primarily used in CNC machine tool applications, including milling machines, lathes, grinding machines, and machining centers where coordinated multi-axis servo control is required. It is also found in general industrial automation systems requiring precise motion control. The modular architecture of the SIMODRIVE 610 system makes it well suited for machine builders who require scalable, multi-axis drive solutions within a compact cabinet footprint.

Common Fault Codes

F01: DC link overvoltage detected on the power supply module
Check incoming AC supply voltage for overvoltage conditions. Verify regenerative feedback circuit is functioning correctly. Inspect braking resistor if fitted.
F02: DC link undervoltage — DC bus voltage has dropped below the minimum threshold
Check AC input supply voltage and connections. Verify input fuses and contactor. Check for excessive load on the DC bus.
F03: Overcurrent on DC link bus
Identify which axis module is drawing excessive current. Check motor windings for short circuit or ground fault. Inspect power cables between drive and motor.
F04: Power supply module overtemperature
Check cooling fan operation and airflow through the cabinet. Clean air filters. Verify ambient temperature is within specification. Reduce duty cycle if necessary.
F05: Phase failure on AC input supply
Check all three phases of the incoming AC supply. Inspect input fuses, contactors, and wiring connections to the power supply module.
F06: Ready signal fault — power supply module has not reached ready state
Check DC link pre-charge circuit. Verify all axis modules are correctly seated and connected. Review system startup sequence and interlock conditions.
F07: Internal power supply fault within the module
Inspect internal fuses within the power supply module. If fuses are intact, the module may require repair or replacement of internal power supply boards.

Frequently Asked Questions

What is the function of the 6SC6100-0NA21 within the SIMODRIVE 610 system?

The 6SC6100-0NA21 is a power supply module that provides regulated DC link bus voltage to the axis drive modules in a SIMODRIVE 610 multi-axis servo system. It acts as the central power source for the modular drive configuration.

Is the SIMODRIVE 610 power supply module compatible with regenerative braking?

Yes, the SIMODRIVE 610 power supply modules support regenerative feedback, allowing braking energy from the axis modules to be returned to the AC supply network rather than dissipated as heat.

What input voltage does the 6SC6100-0NA21 require?

The module is designed for a 3-phase 400 V AC input supply, which is standard for European industrial installations.

Can the 6SC6100-0NA21 be used with SIMODRIVE 611 axis modules?

The SIMODRIVE 610 and SIMODRIVE 611 are separate product families with different DC bus and mechanical configurations. The 6SC6100-0NA21 is intended for use within the SIMODRIVE 610 system and is not directly interchangeable with SIMODRIVE 611 components.

What cooling method does the SIMODRIVE 610 power supply module use?

The module uses forced air cooling and must be installed in a cabinet with adequate ventilation and airflow to maintain operating temperatures within specification.

Troubleshooting

DC link does not charge on system power-up

Check AC input supply voltage at the module terminals. Verify input fuses and main contactor operation. Inspect the pre-charge resistor circuit for open circuit.

Replace blown input fuses with correct rated types. If the pre-charge circuit is faulty, inspect and replace the pre-charge resistor or associated relay. Verify contactor coil voltage and operation.

Power supply module trips immediately after enabling

Check for short circuits or ground faults on the DC bus. Disconnect axis modules one at a time to isolate the faulty module. Measure insulation resistance of motor cables.

Repair or replace the axis module or motor cable causing the fault. Ensure all DC bus connections are secure and correctly rated. Re-enable the system after isolating the fault.

Overtemperature fault occurring during normal operation

Measure ambient temperature inside the cabinet. Check cooling fan operation and direction of airflow. Inspect air filters for blockage.

Clean or replace blocked air filters. Repair or replace faulty cooling fans. If ambient temperature exceeds 45 °C, improve cabinet ventilation or add supplementary cooling.

Intermittent ready signal loss during operation

Check DC link voltage stability using a DC voltmeter or oscilloscope. Inspect all DC bus connections and module seating. Review event logs on the CNC controller for associated fault codes.

Tighten any loose DC bus connections. Re-seat axis modules to ensure good electrical contact. If DC link voltage is unstable, inspect the power supply module capacitors for degradation and arrange module repair.

No output on DC bus despite AC supply being present

Verify AC input voltage at all three phases. Check internal fuses within the power supply module. Inspect the rectifier bridge for open-circuit diodes.

Replace blown internal fuses with correct rated types. If the rectifier bridge is faulty, the module requires workshop repair or replacement of the rectifier assembly.
