Overview

The A5E00714563 is a SINAMICS power block drive board from the A5E00714560 series — the family of second-generation IGBT gate driver (IGD2) repair assemblies that Siemens produced for the SINAMICS G120, G120C, G150, and S120 chassis drive platforms.

This series includes the A5E00714560, A5E00714561, A5E00714562, and A5E00714563, each addressing a specific voltage class and current rating combination in the SINAMICS chassis drive product range.

The A5E00714563 is a Siemens-produced repair part intended to restore the inverter power block of SINAMICS chassis drives when the gate driver board or the associated IGBT module has failed.

As with all members of the A5E00714560 series, the assembly integrates the IGD2 gate driver board with the IGBT output module as a matched pair — ensuring that the gate drive characteristics precisely match the switching requirements of the specific IGBT device used.

The A5E00714560-series boards represent a distinct generation from the IGD1-based power blocks used in MICROMASTER drives.

The IGD2 incorporated higher-speed fibre-optic interfaces compatible with the SINAMICS Control Unit (CU320, CU310, and similar), improvements in gate desaturation detection response, and a current measurement architecture matched to SINAMICS vector control's closed-loop current regulation requirements.

Key Specifications

A5E00714560 Series — Power Block Family Overview

The A5E00714560 series comprises multiple boards covering different voltage and current combinations across the SINAMICS chassis drive range. In the 480V voltage class, the series includes boards at 380A and 490A current ratings, each paired with the specific IGBT module matched to that power level.

The A5E00714563 extends the series to address specific configurations within the SINAMICS drive lineup not covered by the immediately adjacent part numbers.

Each board in this series shares the same fundamental IGD2 gate driver architecture: fibre-optic PWM command reception from the SINAMICS Control Unit, six-position gate pulse generation and distribution to the IGBT bridge positions, hardware desaturation detection, and bidirectional current measurement return to the control unit.

The differences between individual part numbers in the series reflect differences in the IGBT module specification (different current ratings, different voltage classes) and in the specific gate drive resistor values and driver current capabilities calibrated for each IGBT device.

IGD2 Gate Driver — Second-Generation Advances

The IGD2 generation introduced several improvements over the IGD1 used in MICROMASTER 440 drives. The fibre-optic interface on the IGD2 supports higher data rates compatible with the SINAMICS platform's faster control cycle times.

Where MICROMASTER 440 uses a relatively conservative PWM control cycle, SINAMICS vector and servo control requires shorter control cycle times — down to 125 microseconds in some configurations — which demands faster gate driver response and higher-fidelity current feedback.

The desaturation detection circuit in the IGD2 also operates with improved speed and sensitivity.

In the event of an IGBT short-circuit fault, the IGD2 detects the failed turn-on within the IGBT's conducting event and initiates soft turn-off — reducing the rate of current fall to avoid overvoltage spikes from stray inductances. This soft turn-off protection is particularly important in the SINAMICS chassis drive power range, where the IGBT currents and the associated di/dt during turn-off generate significant inductive voltage transients.

Drive Power Block Replacement Procedure Context

Replacing an IGD2 power block in a SINAMICS chassis drive requires working inside the drive's power section with the DC bus confirmed discharged and locked out. The SINAMICS platform includes a DC bus indicator LED — this indicator must be confirmed off before any power section work begins. After isolation of the AC supply, a minimum discharge waiting time (typically five minutes) must be observed, followed by direct measurement of the DC bus voltage with a calibrated voltmeter to confirm safe voltage levels before touching any power section components.

The A5E00714563 assembly mounts on the drive heatsink, with the IGBT module base plate in thermal contact with the heatsink surface.

Thermal interface material must be applied to this contact surface during installation. After installation, reconnect the fibre-optic cables to the correct positions — the individual cables are polarity-independent but must connect the correct drive axis to the correct gate driver board position.

FAQ

Q1: How is the correct A5E00714563 confirmed for a specific SINAMICS drive before ordering?

The label on the installed power block board carries the A5E part number that was originally specified for that drive. Check the label on the board that failed — the A5E number on that label is the definitive reference for the replacement.

Also record the drive's complete type designation from the drive's rating plate.

Siemens' spare parts documentation cross-references drive type to power block part number — confirming both the board label and the drive type against this documentation removes any ambiguity before ordering.

Q2: A SINAMICS G120 drive tripped on F30022 (ground fault detected) with no load connected. Could the A5E00714563 power block be generating a false fault?

F30022 is generated when the SINAMICS Control Unit detects a significant imbalance in the three-phase output currents, consistent with a ground fault. The power block's current measurement circuit provides the phase current data used for this detection.

A failed current measurement channel in the IGD2 board produces an apparent current imbalance even with no load connected, triggering F30022. Confirm by checking whether the three output current readings in the drive's diagnostic display show a realistic zero-current condition — a non-zero reading on one channel with the drive in a stopped state confirms a current measurement fault on the power block.

Q3: The drive showed F30021 (IGBT overcurrent) and then the power block was found to have a physically damaged IGBT module. Should the Control Unit or any other boards be checked before installing the replacement A5E00714563?

Yes. An IGBT short-circuit event creates a voltage transient on the DC bus that propagates through the drive's internal wiring. The Control Unit's voltage supply filtering provides some protection, but severe fault events can stress the Control Unit's power supply components.

Before installing the replacement power block, power up the drive with the power block disconnected (if possible) to verify the Control Unit's 24V supply is within specification. Also check the pre-charge circuit, DC bus fuses, and any snubber capacitors that may have been exposed to the fault transient.

Q4: The A5E00714563 is listed as discontinued. Is the A5E36717xxx series a confirmed successor?

The A5E36717xxx series represents the next generation of SINAMICS power block assemblies and serves as the successor family to the A5E00714560 series. Specific successor mapping — which A5E36717xxx number replaces A5E00714563 specifically — should be confirmed against Siemens' spare parts migration documentation for the specific drive type and production state.

The successor incorporates the next-generation IGD2 gate driver board while retaining functional compatibility with the same SINAMICS drive family.

Q5: Can the A5E00714563 be tested before installation to verify it is not damaged?

A basic functional test of an IGD2 power block without the drive chassis is not straightforward, as the board requires the SINAMICS fibre-optic interface and power supplies to operate.

The most reliable approach for an aftermarket board is to procure from a supplier that offers functional test documentation — confirming the board was powered up on a SINAMICS-compatible test rig and all gate channels were verified active.

This provides reasonable assurance before installation in a production drive.
