MAGPOWR Dancer / Follower Arm Control

MAGPOWR Dancer / Follower Arm Control

Need control of a dancer, follower arm or both? No problem, as MAGPOWR’s DFC-90 and DFC-A low-cost tension controls can handle either operation mode.

Dancer Mode: The DFC-90 and DFC-A are full PID closed-loop dancer controls, controlling web tension by sensing the position of the dancer arm through a DFP or DFP-2 Position Sensor and adjusting the clutch, brake or motor control torque accordingly to maintain the dancer position set point.

Follower Arm Mode: 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 Sensor and a follower arm. An optional Stop Multiplier provides additional stopping torque to help stop large unwind rolls.
