The FR-A800-R2R Series of Variable Frequency Drives (VFD) from Mitsubishi Electric Automation is ideal for end users and machine designers looking for an optimized control solution for continuous roll-to-roll processing. The drive builds on the performance and functionality of the standard FR-A800 Series VFD, with enhanced firmware engineered for unwinding and rewinding processes such as coating, laminating, slitting, drawing and extruding.
The drive is equipped with dedicated functions, such as tension sensorless torque control and tension sensor feedback speed control. Variable tension is applied to the material to maintain constant flow on the winding and unwinding sides, helping to eliminate imperfections such as wrinkles or deformation.
