Siemens 6SE7031-2EF60 – SIMOVERT MASTERDRIVES Vector Control Frequency Converter

The Siemens 6SE7031-2EF60 is a frequency converter from the SIMOVERT MASTERDRIVES Vector Control series, designed in a chassis format for controlling the speed and torque of electric motors in industrial applications.

The converter receives a three-phase supply ranging from 380 to 480 V AC and generates an output with variable voltage and frequency for the motor, controlling drive operation according to the configured parameters.

Thanks to its Vector Control technology, the 6SE7031-2EF60 enables precise management of the motor’s main operating variables and is suitable for applications requiring stability, high dynamic performance and operational continuity.

Vector control allows accurate regulation of motor speed and torque, even when the load varies during the production cycle.

The Siemens 6SE7031-2EF60 has a rated current of 124 A and a typical power rating of 55 kW. The chassis design with IP00 protection is intended for installation inside a suitably sized and protected electrical cabinet.

The air-cooling system helps dissipate the heat generated during operation. To ensure drive reliability, the ventilation paths must be kept clean and the condition of the fans and components subject to wear must be checked periodically.

Before installation or replacement, the complete product part number, any options indicated after the letter “Z”, the hardware configuration, control board, firmware and drive parameters must be checked.

The product belongs to the established SIMOVERT MASTERDRIVES range and has been discontinued. Repair and regeneration help extend the service life of existing systems, reducing the risks and costs associated with obsolescence and the limited availability of spare parts.

❓ Frequently asked questions – Siemens 6SE7031-2EF60

Can I send my faulty Siemens 6SE7031-2EF60 for repair?

✔️ Yes. After completing the request form, E-Repair Customer Care will provide all the necessary instructions for shipping the converter to the laboratory.

Can I receive a 6SE7031-2EF60 in advance?

✔️ Yes. If a new or regenerated product is available in stock, it can be shipped in advance to help reduce plant downtime.

Is the converter tested before it is returned?

✔️ Yes. Every repaired or regenerated Siemens 6SE7031-2EF60 undergoes electronic inspections and functional testing on a dedicated test bench before delivery.

Can the 6SE7031-2EF60 be connected directly to the three-phase mains supply?

✔️ Yes. The 6SE7031-2EF60 is a frequency converter powered by a three-phase mains supply ranging from 380 to 480 V AC, at 50 or 60 Hz. The connection must be carried out by qualified personnel in compliance with the required protection devices, cable sizing and technical specifications for the installation.

What is the difference between the 6SE7031-2EF60 and the 6SE7031-2TF60?

✔️ The 6SE7031-2EF60 is a frequency converter powered directly by a three-phase mains supply at 380–480 V AC. The 6SE7031-2TF60 is instead an inverter powered by the DC link at 510–650 V DC. The two products must therefore not be considered equivalent without a thorough technical assessment.

Does the replacement product need to be reparameterised?

✔️ Yes. Before replacement, it is advisable to back up the parameters where technically possible. The motor data, control mode, firmware, control board and any installed optional modules must be checked on the replacement unit.

What faults may indicate a malfunction of the 6SE7031-2EF60?

✔️ A malfunction may prevent the motor from being activated, cause sudden drive shutdowns, overcurrents, overheating, irregular speed or torque regulation, or generate fault indications.

The diagnosis must also include the motor, power and control connections, cables, fans, temperature sensors, control board and parameter configuration.

Why is it important to check the cooling system?

✔️ Dust accumulation, fan deterioration or reduced airflow may cause the internal temperature to rise and compromise the reliability of the power electronic components.

Preventive maintenance of the ventilation system helps reduce the risk of sudden shutdowns and extend the converter’s service life.

Why is it important to check the options indicated after the letter “Z”?

✔️ The options indicated after the letter “Z” may identify specific hardware configurations, electronic boards or equipment fitted to the converter. Before repair or replacement, the complete part number shown on the product nameplate must therefore be provided.
