Servotorq I
Servotorq is the underlying hardware and firmware technology at the heart of Overview's Integrated Servo Drives.
Servotorq optimises drive motion to ensure smooth, accurate and rapid movements.
Servotorq's comprehensive SDK allows access to a wide range of performance parameters and control inputs, enabling customers to achieve maximum performance across a broad range of applications.
Servotorq I uses a single-stage PID control loop to deliver precise velocity and both absolute and relative move control.
For enhanced performance, Miranda and Atlas feature a dynamic trajectory generator, further refining fit to the ideal S-curve motion.
Integrated Servo Drives powered by Servotorq I offer torques ranging from 40mNm to 2Nm and provide speeds up to 720°/s.
Servotorq II
Servotorq II is the latest evolution of Servotorq technology, delivering a much tighter control loop and significantly faster reaction times.
Servotorq II maintains the Servotorq I core command set, allowing seamless integration whilst interconnected PID controllers and additional motion filtering capability, allows customers to extract every ounce of performance from each drive across a wide variety of applications.
The fully interruptible third order trajectory generator within Servotorq II make equipped Drives ideal for highly dynamic applications. Versatility and application potential are further expanded by the introduction of CAN control and Helios’ on-drive inertial stabilisation.
The Servotorq II Drives offer torque of up to 4Nm and speeds up to 1000°/s.

Best in Class Performance
Integrated Servo Drives are not traditional motors! They are intelligent precision solutions for pointing challenges. Created by Overview in the UK, from the ground up, to provide market leading performance in a broad range of applications where the following key features are valuable
Precision
Servotorq drives offer direct-drive precision, delivering accuracy and repeatability levels of up to 0.055° (96 x 10-6 rad).
Silence
The silent operation of Integrated Servo Drives brings significant benefits in situations where covert or unobtrusive operation is required.
Compact
By reducing the number of drive components, Servotorq technology presents a compact footprint without compromising speed and agility.
Intelligent
Overview’s advanced Servotorq trajectory generator dynamically controls motion in real time by integrating load, drive, and demand, delivering optimised performance and ease of use.
Zero Backlash
Integrated Servo Drives directly drive payloads with no intermediate belts or gears, delivering true zero backlash, resulting in higher accuracy, lower cost and enhanced reliability.

Frequently asked questions
Here are some common questions relating to our Integrated Servo Drives.
Can’t find the answer you’re looking for?
Each Integrated Servo Drive includes a 2-year standard warranty. Extended warranty periods are available dependent on application.
Select “Ask an expert” for further information.
Yes, the control commands are almost identical across all our drives. All drives support I2C control interfaces. Helios also supports CAN.
You can therefore mix and match the drives across motion axes of your application, safe in the knowledge the control software being used will work effectively on all Drives.
Motors are for hair dryers!
Generally, motors run open loop with no positional control. Drives are precision engineered solutions to meet the challenges of the very precise pointing and control of payloads.
Overview’s unique Integrated Servo Drives contain in-house designed precision BLDC (Brushless Direct Current) motors that are highly optimised for torque, pointing precision and ultrasmooth motion. An Integrated Servo Drive contains these highly specialised motors, the drive electronics to power these, a precision position encoder and a sophisticated digital servo in a single integrated package.
Overview’s unique Integrated Servo Drives have been designed from the ground up, in the UK, to meet the exacting needs of accurate and agile pointing challenges such as the pointing of sensors.
Integrated Servo Drives are direct drive. The payload is mounted directly to the drive with no intervening belts or gears resulting in true zero backlash motion and significant reliability benefits.
“Integrated” refers to the inclusion and integration within the Drive of four key elements:
- A specialised, custom designed brushless DC motor optimised for precise positioning
- High performance drive electronics for this motor
- A custom developed, high precision optical rotary encoder providing real time position feedback
- An advanced “Servotorq” digital servo
all in a small, convenient, cost effective and easy to use product.
The supply voltage needed by Overview’s Integrated Servo Drives varies from across the range of Drives offered but is between 12 and 48V DC. Specific supply voltage information for each Drive can be found at the top of each product page.
Quick Start Guides and comprehensive Technical Manuals are available for all our Drives, providing the key information needed to get our Drives moving quickly.
Yes. Overview offers a Drive Development Kit that allows a PC/laptop to connect easily to our drives which includes product specific interconnecting cables. Using the Drive Development Kit new users can be up and running in minutes. The Servotorq Accelerator software included in the Drive Development Kit provides an open SDK to allow users to set up and control the powerful features of the Drives in their own software. A full Control Manual is also available for all Servotorq enabled Drives providing a detailed breakdown of all Servotorq commands and parameters.
