What an AC servo drive is
An AC servo drive, or servo amplifier, powers and controls a servo motor from mains supply. It rectifies the AC input to a DC bus, then uses an inverter of power transistors switched by PWM to produce controlled three-phase current in the motor. Nested current, velocity and position loops use encoder feedback to follow commands from pulse and direction, analogue or industrial Ethernet. Modern drives add auto-tuning, vibration suppression and safety functions such as safe torque off.
When engineers choose an AC servo drive
Choose an AC servo drive for mains-powered machines with servo axes from tens of watts to many kilowatts, such as packaging, machine tools and robotics. It gives precise, dynamic control with standard industrial interfaces. The trade-offs are cabinet space, wiring, EMC measures and the need to match motor and feedback. For low-voltage or mobile machines, a DC drive is more suitable; for many axes in one cabinet, a multi-axis drive may save space.
How to specify the SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters
Send these with your enquiry and an engineer can confirm the right MOVIDRIVE system / technology single-axis application inverters variant or an equivalent:
- Supply voltage and phases (V AC)
- Continuous and peak output current (A rms)
- Motor and feedback compatibility
- Command interface: pulse, analogue, EtherCAT, PROFINET and so on
- Safety functions, such as STO, and their rating (SIL, PL)
- Braking resistor and regenerative energy (W, J)
- Ambient temperature, mounting and cooling
Common mistakes to avoid
- Sizing on motor rated current without the drive's peak duration
- Ignoring regenerative energy on fast decelerations or vertical axes
- Leaving out EMC filtering and screened motor cables
- Mixing motor and encoder types the drive does not support
SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters: frequently asked questions
What is the SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters?
Single-axis application inverters for 200-240 V or 380-500 V three-phase supplies from 0.55 to 315 kW, with 200 % overload, built-in STO and fieldbus versions for PROFINET, EtherNet/IP, Modbus TCP or EtherCAT. Published series figures include power 550 W, power 315,000 W. It is made by SEW-EURODRIVE GmbH & Co KG; Specify Motion can help source it or propose an equivalent.
Who makes the SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters?
The SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters is made by SEW-EURODRIVE (SEW-EURODRIVE GmbH & Co KG) and is listed here for engineers comparing options. Specify Motion is not affiliated with SEW-EURODRIVE GmbH & Co KG; brand names are used only to identify the product.
What is the power of the SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters?
The published series minimum power is 550 W. Individual models and sizes in the MOVIDRIVE system / technology single-axis application inverters range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the SEW-EURODRIVE MOVIDRIVE system / technology single-axis application inverters?
Yes. Our engineers can propose an equivalent built around your load, speed and environment. An engineer confirms the fit against your application before recommending anything.
Does a servo drive need a braking resistor?
When a servo motor decelerates, it acts as a generator and returns energy to the drive's DC bus. If the bus capacitors cannot absorb it, the voltage rises and the drive trips. A braking resistor dissipates the energy as heat. Fast decelerations, high inertia and vertical axes usually need one.
What is safe torque off on a servo drive?
Safe torque off, or STO, is a safety function that removes power that could produce torque at the motor, without disconnecting the drive supply. It is defined in IEC 61800-5-2 and used as part of a machine's safety system. Check the safety level achieved and wiring requirements.
