Integrated Motion Controller

High-precision positioning and synchronization with reduced costs and system complexity

To optimize performance, many applications across all industry sectors have a need for precise positioning and synchronization. These applications include:

• rotary tables 
• packaging machines
• labelling machines 
• conveyors 
• extruders
• palletizers

To date, positioning and synchronization operations have been performed using servo drives. However, servo equipment is expensive; it is difficult to commission and requires additional cabling. And, as servo drives do not work with open loop control systems, there is a high failure rate. Many applications do not require the high dynamic performance offered by a servo drive. An alternative was to use an AC drive. But, until now, an additional internal or external module or an encoder on the motor was required.

Danfoss Drives has developed an innovative alternative to servo control. The Integrated Motion Controller (IMC) is functionality that enables an AC drive to perform high-precision positioning and synchronization operations without the need for additional modules or hardware. IMC is now configurable in the software of the VLT® AutomationDrive FC 302.

IMC has many advantages. It works with all conventional motor technologies, with closed loop or open loop control, and offers sensor less homing with torque detection. Drives are adapted to the applications through simple parameterization. This means that knowledge of servo technology or programming languages is not required. As no encoder or additional cables are needed, engineering, installation and commissioning time and costs can be reduced.
