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

  • palletizers
  • rotary tables
  • cutting machines
  • packaging machines

In the past, applications requiring positioning and synchronization have typically used servo drives and additional motion controllers. However, such equipment is expensive and complex and requires a high level of effort in relation to engineering, installation and commissioning. As servo drives use closed-loop control, a feedback device is needed. This adds to the complexity and cost and is an additional potential failure source.

Did you know that many of these applications don’t actually require the high dynamic performance offered by a servo drive? An alternative would be to use a standard AC drive but, so far, an additional external motion controller and feedback device on the motor have been required.

To reduce complexity and the need for additional modules or hardware, Danfoss Drives developed the Integrated Motion Controller (IMC) in the VLT® AutomationDrive FC 302. As an innovative alternative to complex motion controllers, IMC offers high-precision position control as well as multiple features for positioning and synchronizing with a standard AC drive. Position control can be achieved with or without a feedback device depending on the required functionality and performance.

Save costs and time

The motion features of IMC have been added to the well-known and highly valued features and properties of the VLT® AutomationDrive FC 302. They offer motion control with all conventional motor technologies, and all features can be configured and adapted to your applications through simple parameterization. This makes complex programming knowledge unnecessary and significantly reduces engineering, installation and commissioning time and costs.

IMC is a great way of fulfilling high-precision positioning and synchronization tasks with reduced costs and system complexity. It’s one of many innovative solutions developed by Danfoss Drives.
