| | | APPLICATIONS DFC-90: Dancer or Follower Arm Control of magnetic particle clutch or brake FEATURES/BENEFITS Superior control performance at an affordable price Enhanced dancer algorithm and tuning method for performance Non-interactive Core and Full Roll adjustments DFC-90: Current regulate 90 vdc output in four selectable ranges DFC-A: Switch selectable 0 to 10 vdc or 4 to 20 ma output Compact enclosure requires minimal space Simplicity of DIN rail mounting The DFC-90 and DFC-A are low cost tension controls with two operating modes. They can be used in Dancer or Follower Arm tension control applications. In dancer control applications, the DFC-90 and DFC-A are closed loop dancer controls. They control web tension by sensing the position of the dancer arm through a DFP or DFP-2 Position sensor manufacturers and adjusting the clutch, brake or motor control torque accordingly to maintain the dancer position set point. An advanced control algorithm provides optimum control and ease of use. In follower arm applications, the DFC-90 and DFC-A control web tension by compensating for measured changes in the roll diameter. Roll diameter changes are measured through the DFP or DFP-2 Position Detection and a follower arm. An optional Stop Multiplier provides additional stopping torque to help stop large unwind rolls. Setup adjustments are made using easily accessible potentiometers, and all adjustments are intuitive and clearly marked. The DFC-90 and DFC-A Dancer/Follower Arm Controls meet all CE and UL requirements for safety and electrical noise immunity. | | PARTSANDORDERINGINFORMATION PartNumber Description DFC-90 Dancer / Follower Arm Control DFC-A Dancer / Follower Arm Control DFP Dancer / Follower Arm Position Sensor DFP-2 Dancer / Follower Arm Position Sensor 9A13-1RPL Analog output meter (0-100%) | | |
