Overview

The 6SE7016-1EA84-1HF3 is an inverter drive board for Siemens' SIMOVERT Masterdrives series. The SIMOVERT Masterdrives was Siemens' flagship AC drive platform across its production generation — a vector control drive system widely deployed in demanding industrial applications including machine tools, conveyors, hoists, winders, and process drives.

The -1HF3 suffix designates the board variant within the 6SE7016 series, and the board carries UL 94V-0 flammability rating, confirming it meets the required flame-resistance standard for industrial PCB applications.

This board is the internal control or inverter circuit PCB within the SIMOVERT Masterdrives unit it belongs to.

The Masterdrives architecture uses modular internal boards that separate specific electronic functions — control logic, gate driving, current measurement, and power switching coordination — into replaceable board assemblies. 

The 6SE7016-1EA84-1HF3 performs the inverter drive function within its specific drive frame size and rating.

Siemens Masterdrives remain installed across global industrial facilities in large numbers.

Replacement PCB supply keeps these drives operational without requiring complete drive replacement — a significant cost advantage for maintenance operations managing multiple Masterdrive units.

Key Specifications

SIMOVERT Masterdrives — The Platform Context

Siemens designed the SIMOVERT Masterdrives as a modular, high-performance drive system intended for applications where standard variable frequency drives fell short.

Vector control — the core technology of the Masterdrives — allows independent control of a motor's magnetising current and its torque-producing current, giving the drive the ability to regulate torque directly rather than only voltage and frequency.

This torque control capability made the Masterdrives the choice for applications requiring precise speed and torque at all operating conditions: cranes and hoists where load variations are extreme, machine tools where dynamic servo-like response is expected from a standard induction motor drive, winders where tension must be held constant across changing roll diameter, and test benches where controlled loading is the primary requirement.

The board-level architecture supported this versatility. Individual PCBs handled defined functions.

When a board failed, that specific board could be replaced without disturbing the rest of the drive. The 6SE7016-1EA84-1HF3 was one such serviceable board within this architecture.

Inverter Drive Board Function

The inverter board in a variable frequency drive is where DC bus voltage becomes variable-frequency, variable-voltage AC output to the motor. The DC bus — supplied by the drive's rectifier section — provides a fixed DC voltage.

The inverter board controls the IGBT transistors in the power section, switching them in a precisely timed pattern to synthesise the AC waveform the motor requires.

The timing pattern — the PWM scheme — is generated by the inverter board's logic.

The board receives the desired output frequency and voltage from the control section, calculates the correct switching pattern for each half-cycle, and drives the IGBT gate circuits accordingly. 

The accuracy of this switching determines the quality of the motor's current waveform, which directly affects the motor's thermal loading, acoustic noise, and torque smoothness.

When the inverter board develops a fault — a damaged gate driver, a failed current measurement circuit, or corrupted control logic — the inverter output is disrupted.

The drive may show an overcurrent alarm, output asymmetry, or simply fail to produce a motor rotation signal. Replacing the inverter board restores the PWM generation function.

UL 94V-0 Flame Rating

The board carries a UL 94V-0 flammability rating. This is the highest flame resistance classification in the UL 94 standard for plastic materials used in electronic equipment.

A 94V-0 rated board self-extinguishes within 10 seconds after the ignition source is removed, and does not produce burning drips that could spread flame.

In industrial drive applications — where the board is enclosed in a metal cabinet often shared with motor cables carrying significant power — flame resistance of the board material is a relevant safety property.

The 94V-0 rating confirms the board meets this requirement.

FAQ

Q1: The Masterdrive shows an F002 or overcurrent fault that trips immediately on motor start. Could the inverter board be at fault?

An immediate overcurrent trip on motor start with no mechanical overload is consistent with an inverter board fault — specifically, a gate driver that is not correctly controlling the IGBT switching.

The result is an uncontrolled current surge that triggers overcurrent protection. Before replacing the board, verify the motor and cable insulation are good (rule out a motor or cable fault), and confirm the DC bus voltage is correct. 

If both are confirmed normal, the inverter board is the primary suspect.

Q2: The drive outputs to only two of three motor phases. The motor runs hot and vibrates abnormally. Is this an inverter board issue?

Missing phase output is typically caused by a failed IGBT in the power section, or a failed gate driver on the inverter board that is not firing the IGBT for that phase.

Check the gate signals for each phase at the IGBT gate terminals — if one phase's gate signal is absent or distorted, the inverter board's gate driver for that phase has failed. 

If the gate signals are all present but one phase is missing at the output, the IGBT for that phase is the fault.

Q3: After replacement of the 6SE7016-1EA84-1HF3, the drive needs to be re-parameterised. What parameters are specific to the inverter board?

The inverter board itself does not store parameters — drive parameters are held in the control board's memory.

After an inverter board replacement, the drive's existing parameters remain in the control board. 

However, confirm the board's hardware revision is compatible with the installed firmware version.

If a firmware mismatch exists, download the appropriate firmware. Perform a test run at low speed before returning to production.

Q4: The board was exposed to moisture during storage. Can it be used after drying?

Moisture exposure risks depend on the extent of exposure and whether corrosion has occurred.

A board exposed briefly to high humidity and then dried in a warm, clean environment may be undamaged. 

A board that was wet for an extended period should be inspected under magnification for corrosion on the copper traces and component pins before being installed. 

Corroded contacts or traces that appear intact visually can fail under operating conditions.

When in doubt, do not install a moisture-exposed board without thorough professional inspection.

Q5: Are there multiple internal references (A5E numbers) for the 6SE7016-1EA84-1HF3? Does this affect interchangeability?

Yes. The board has been produced in multiple hardware revisions, each carrying a different A5E internal reference.

Minor hardware revisions within the same order number are generally cross-compatible, as Siemens uses revision control to manage design updates while maintaining functional compatibility. 

However, confirm that the board's production revision level matches the expected range for the specific drive firmware installed. 

If the drive uses a later firmware that requires a minimum board revision, an earlier revision board may not function correctly.
