More Information

Overview Manuals DC Link Energy Resistor Connection I/O and Busbars Thermal Limits

Features:

  • The booksize module diverts excess DC-link energy to an external braking resistor.
  • A 770 V threshold controls the braking path across the 510 to 720 V DC operating range.
  • Separate 24 V electronics, digital I/O and high-current busbars coordinate the module with the S120 drive.
Regenerative motor energy raises the voltage of the connected SINAMICS S120 DC link.

The braking module detects the threshold and switches the external resistor into the energy path.

The resistor converts the diverted energy into heat while digital status returns the module condition to the drive system.

The Siemens 6SL3100-1AE31-0AB1 SINAMICS S120 Braking Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Moving regenerative energy from the DC link to the resistor

  • Operating range: The module works on a 510 to 720 V DC link.
  • Activation: The braking path switches at the 770 V threshold.
  • Peak path: Up to 100 kW is handled for two seconds.
  • Continuous path: The documented rated braking power is 1.5 kW.

Keeping the external dissipation path within its wiring limit

  • External resistor: Electrical braking energy is converted into heat outside the module.
  • Cable boundary: The route to the braking resistor is limited to 10 m.
  • Conductor layout: The resistor cable remains separate from low-voltage signal wiring.
  • Thermal path: Resistor placement must allow the converted heat to leave the installation.

Separating control signals from power-current paths

  • Digital inputs: Two inputs accept the documented -3 to 30 V signal range.
  • Digital outputs: Two 24 V outputs carry up to 100 mA per channel.
  • Control busbar: The 24 V busbar carries up to 20 A.
  • DC link busbar: The high-voltage busbar path is rated for 100 A.

Relating power loss, airflow and booksize mounting

  • Module loss: The braking module contributes 20 W of power loss.
  • Cooling: Natural convection moves heat away from the enclosure.
  • Mounting width: The 50 mm booksize width fixes the occupied drive-stack space.
  • Air path: The 380 mm height and 270 mm depth remain clear for the documented installation.
Description
Siemens 6SL3100-1AE31-0AB1 is a SINAMICS S120 booksize braking module. It monitors the drive DC link and routes excess regenerative energy to an external braking resistor so that the resistor can convert that electrical energy into heat.

Across its 510 to 720 V DC link range, 6SL3100-1AE31-0AB1 activates the braking path at 770 V. The 24 V electronics supply powers the monitoring and switching circuits independently of the high-voltage busbars.

The braking path of 6SL3100-1AE31-0AB1 is rated at 1.5 kW with a maximum of 100 kW for two seconds. A braking-resistor cable no longer than 10 m connects the module output to the external resistor, tying peak power, conductor routing and resistor placement to the same installation.

Two digital inputs and two 24 V digital outputs let 6SL3100-1AE31-0AB1 exchange enable and status signals with the surrounding drive system. The 24 V and DC-link busbars carry different current levels, while natural convection removes the module heat inside the booksize assembly.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does Siemens 6SL3100-1AE31-0AB1 activate during motor deceleration?
Siemens 6SL3100-1AE31-0AB1 monitors the DC link and switches the external braking resistor when regenerative energy raises the link to its 770 V threshold.
Which braking resistor cable limit applies to 6SL3100-1AE31-0AB1?
The connection from 6SL3100-1AE31-0AB1 to the external braking resistor must remain within the documented 10 m maximum.
Can Siemens 6SL3100-1AE31-0AB1 dissipate 100 kW continuously?
No. Siemens 6SL3100-1AE31-0AB1 is rated for 1.5 kW braking power and a 100 kW maximum lasting two seconds.
What should be checked if 6SL3100-1AE31-0AB1 reports no braking action?
For 6SL3100-1AE31-0AB1, verify the 24 V electronics supply, DC-link voltage, resistor continuity, cable length, digital control state and busbar connections.
How are control signals separated from the power path on Siemens 6SL3100-1AE31-0AB1?
Siemens 6SL3100-1AE31-0AB1 uses two digital inputs and two 24 V outputs for control while separate busbars carry 24 V and DC-link current.
Why does cabinet airflow matter for 6SL3100-1AE31-0AB1?
Natural convection removes the 20 W module loss from 6SL3100-1AE31-0AB1, while the external resistor has its own larger heat-dissipation requirement.
