INVEOR line of drive controllers

The INVEOR M is a drive controller with a modular configuration, which aligns itself ideally to the customer’s requirements and the application in hand. Thanks to its smart motor adaptation concept and particularly robust design, the INVEOR M meets the special request made by customers for a motor-mounted device. In terms of integration in the customer’s application, the INVEOR M can be perfectly adapted to the most important interfaces with the customer application. For us, this means: Smart connections on five levels. 


Five sizes covering motor ratings from 0.25 to 22 kW, each available in the motor-mounted, wall-mounted and cold plate variants. The INVEOR drive controllers can also be fitted with the Safe Torque Off function (STO = functional safety).

INVEOR M product family

The motor-mounted INVEOR M product family comes in five sizes and covers the power range between 0.25 kW and 22 kW in single and three-phase variants, motor-mounted or wall-mounted. You select the size to suit your motor rating in the configuration.

Decentralised drive controller concept

Being installed directly on the motor minimises wiring and installation work and therefore also project planning and installation costs for systems covering large areas. The application section can be extended with ease as no additional space is needed for control cabinets. The individual units can be fully pre-wired, pre-tested and standardised. This makes project planning and commissioning faster than with comparable projects where several drive controllers are fitted in the control cabinet. Shielded motor cables are very short if they are needed at all.

Input/output configuration

The number of inputs/outputs and the model with and without functional safety (STO) can be configured through the choice of integrated application PCB.

Energy efficiency

INVEOR drive controllers satisfy the most stringent requirement of the ECO design directive EN-50598

2. Communication

Through CANopen, EtherCAT, Modbus, Profibus, Profinet and Sercos, the INVEOR is compatible with almost all common control environments. Customers can select the bus system relevant to their needs and thereby ideally integrate the INVEOR into the control environment of their application.

Extensive communication interfaces

The choice of the preferred field bus usually depends on the controller manufacturer used in the system, the geographic region, the functional requirements in terms of speed and network spread and availability of suitable field devices. The INVEOR product family offers a large number of communication options, allowing it to be easily integrated in existing automation processes without having to depart from the fieldbus systems used previously in the application. The fieldbus systems can be selected as options.

3. Operation and observation

For operation, a foil keypad, an external and an integrated MMI handheld controller, operation via an external touchscreen and PC software are available depending on requirements.

Integrated foil keypad

Decentralised drive controllers are easy to access in the field and can also be operated locally thanks to the integrated foil keypad. Changes in direction of rotation, parameter changes, changes in the target value and start and stop commands are therefore possible. What's more, the integrated potentiometer allows target values to be specified with ease. The foil keypad can be selected as an option in the INVEOR configuration.

MMI handheld controller

For commissioning, parameter adaptations and service purposes, our flexible MMI handheld controller is available as an alternative to the PC software. You can edit and save parameters and copy parameter sets from one device to another (clone devices). You can also specify target values and display actual values. The MMI handheld controller is available as an accessory to the INVEOR.

MMI option

The full functionality of the handheld controller, combined with 5 freely selectable status screens, enables parameterization and operation on the drive controller itself. Everything complies with the IP device protection class. The MMI functionality can be selected as an option in the INVEOR configuration.

Touch operating terminal

You can conveniently automate several INVEOR drive controllers without a fieldbus using the touch operating terminal.

INVEOR PC software

The user will get to grips with intuitive PC software interface with virtually no assistance. Commissioning can be easily undertaken by oscilloscope as well as parameter adaptation and the cloning of drive axes. Automatic motor identification, parameter presettings and customer-specific actual value displays automate and speed up application commissioning.

Soft PLC according to IEC 61131-3

The INVEOR provides a freely programmable soft PLC solution with complete access to the device parameters and status data. Programming and depiction can take place in a function block diagram (FBD), structured text (ST) and a list of instructions (AWL). There are 20 technology parameters, which you can use for your specific functions in your application.

Each INVEOR is equipped with the soft PLC solution as standard.

4. Motor adaptation

Thanks to its innovative adaptation concept with a wide range of standard and motor-specific adapter plates, the INVEOR can be used with virtually any motor on the market.

Motor adapter plate

In order to mechanically install the drive controller on the motor, the INVEOR adapter plate (ADP) is used in place of the terminal box. The INVEOR can then be attached directly to this (plug-and-play). Thanks to the large number of adapter plates available, virtually any motor can be adapted. You will find suitable adapter plates in the accessories area.

Mounting adapter plate on wall

If the application does not permit installation on the motor, installation close to the motor is possible. As an alternative to the motor adapter plate, KOSTAL provides an adapter plate for wall mounting. You will find wall mounting plates in the accessories area.

Extensive range of adapter plates

The range includes a large number of adapter plates and intermediate adapters for many common motor types. Specific adapter plates are also available for special motors and can be set up to match requirements and quantities. Please get in touch with your KOSTAL contact for more details.

5. Control process

The regulating concept of the INVEOR is conceived of in such a way that all motors, from asynchronous to synchronous machines, can be operated.

Field-oriented sensor-free regulation for asynchronous and synchronous motors

Compared with controlled processes such as voltage/frequency control, the INVEOR attains improved start-up torques, better efficiency and optimised control quality. Expensive rotary encoder feedback can be dispensed with.


The INVEOR supports asynchronous and synchronous motors of energy efficiency classes IE1 to IE4 according to IEC/EN-60034-30-1

Automatic motor identification

To speed up the process of commissioning the drive controller in combination with external motors, the INVEOR family provides automatic motor identification. Only the type plate data has to be entered to start the identification process.
