SD1 AC Inverter Drives
The SD1 range is the ultimate variable speed drive for you! Easy to set up, and comprehensively specified for use in virtually any application, the SD1 is IMO’s first complete range of variable speed drives which offer STO (SIL2 / SIL3) dependent upon model, along with a huge range of enhanced features, normally found on much more expensive inverter drives.
A range of EMC filter options makes the SD1 suitable for virtually every industrial, commercial or domestic application.

Safety As Standard
The SD1 is the first entry-level range of variable speed drives from IMO which include Safe Torque OFF (STO) as standard. STO is a hugely important safety feature that could prevent industrial accidents and even save lives. But what exactly is STO?
The STO feature ensures that no torque-generating energy is put through the equipment. STO is used to bring the drive to a complete standstill, and also prevents any unexpected or unintentional starting of the motor or drive. It, therefore, enables safe working when for example, the protective door or cover is open or removed.
The advantage of an integrated STO functionality compared with standard safety solutions using electromechanical switchgear is initially the elimination of multiple components and associated part failure and maintenance, but is also considerably quicker due to a shorter switching time than a conventional solution.
STO Benefits:
• Eliminates requirement for conventional
solutions such as power cutting relay or
contactor
• Reduces time and costs associated with
wiring and maintenance
High Performance At Low Speeds
The SD1 range offers torque vector control across all models in the range. IMO is renowned for manufacturing market-leading variable speed drives and the Jaguar range has been long established with high-end features such as torque vector control, however, the SD1 range heralds a new era in feature rich inverter drives due to the sheer array of standard features you would normally expect to find in considerably more expensive models.
The SD1 range delivers stable torque output even at low speeds, allowing the SD1 to be used in an even wider range of applications including lifts and conveyor systems, and high-inertia loads that demand a higher starting torque.
Enhanced Control Functionality
As you would expect, a drive from IMO isn’t your average run-of-the-mill product. We produce solutions which tick every box, every time, and the SD1 is no different.
From offering motor auto-tune which minimises power losses, to PID control which allows motor operation whilst controlling temperature, pressure and flow rate without the use of an external device or controller, together with the inclusion of programmable logic functionality, the SD1 is so packed with features that you wouldn’t believe they fit inside its compact and user-friendly form.
Connected For Communications
Every model in the SD1 range offers communcation capability. The connection is completed by way of twisted-pair to the dedicated RS-485 terminals found on the control terminal block.
Communications are carried out using the Modbus-RTU protocol.
SD1 Application Examples
With the array of advanced features and filter options, the SD1 is suited for use in virtually any application, whether it be industrial, commercial or domestic.
The following are examples of, but not limited to, the type of application where the SD1 can be employed:
