Page 14 OVERVIEW Functions and Features The tension controller LE7-40GU-L is a control device that is used together with a tension detector to perform feedback control on the material tension for the unwinding, intermediate shafts, and winding of a long material. Actuators, such as a powder clutch/brake, servo motor (torque mode), and air clutch/brake, are available, and a power amplifier for a 24VDC system clutch/brake and auxiliary power supply are incorporated.
Page 15 Tension signal Torque control signal Tension controller LE7-40GU-L Features • An exact tension against the target value can be obtained (a tension detector required). • Control not affected by the torque characteristics of the actuator (linearity, temperature characteristic) can be performed.
Page 16 LE7-DCA Torque control signal Proximity switch Tension controller LE7-40GU-L Features • A tension detector is not required. (The actual material tension cannot be grasped.) • Stable control can be performed (not excessively impacted by sudden disturbance). • This control method can also be used by a device that cannot use a tension detector.

Page 91 Tension Input To perform feedback control with the LE7-40GU-L, the tension full scale must be set and the current material tension must be input. For how to input tension for the LE7-40GU-L, four methods are available: LX type tension detector input, strain gauge type tension detector input, analog input, and communication input.
Page 92 The button is flashing while zero adjustment is being executed, and the indication on the button changes to "Zero adjustment being executed". Zero adjustment will be completed automatically. When zero adjustment is completed, the button stops flashing, and the indication on the button returns to "Zero adjustment execution". The parameters total tension, left tension, and right tension become 0N.
Page 93 <Setting method> Hang a weight whose load (N) is known on the detection roller. Apply a static load as close to the full scale tension value as possible. For accuracy, 1/3 or larger of the tension full scale is recommended. Hang a predetermined weight.
Page 94 Precautions • If an abnormal load is obviously put on the tension detector as a result of span adjustment execution (the output voltage of the tension detector is abnormal), an alarm is displayed. Even if an alarm is displayed in span adjustment, the calibration value when span adjustment is executed is stored.
Page 95 ■Manual zero correction If the zero point deviates after machine operation, it can be corrected manually. This correction helps manually adjust the zero point for the tension. <Setting method> Ensure that no load is applied to the detection roller. Using the monitoring of the current tension displayed on the right side of the following screen as reference, set the manual right and left zero corrections.
Page 96 ■Manual span correction During automatic span adjustment, if automatic span operation is not completed due to an error display such as "overload", "underload", and "load imbalance", span correction can be performed manually. <Setting method> Hang a weight for span adjustment on the detection roller. Hang a predetermined weight.
Page 97 Tension detector input voltage monitor The input voltage value from the tension detector is displayed in real number. A tension sensor error or a problem with the mechanical condition of installation may be detected by monitoring voltage applied to the tension detector input terminals ([GRL] and [WHL], [GRR] and [WHR]). For the sensor input type H (LX type), the value is displayed as a number with one decimal place, and for the sensor input type L (strain gauge type tension detector), the value is displayed as a number with two decimal places.
Page 98 Tension filter Set a filter for tension data to be used for each calculation. Set a large value for this setting to make tension change slowly and set a small value to make tension change quickly. If the setting value is too small, fine tension fluctuations will occur. The operation speed suitable for the machine state must be set.

Correct the tension full scale or the tension detector. Check if the load generated by tension is sufficiently applied to the detection roller.
Page 225 Figure C Alarm "Span adjustment excessive load" is displayed. Check if the rated load of the tension detector is excessively large for tension full scale. Correct the tension full scale or the tension detector. The angle of the material wound around the detection roller is excessively large.
Page 226 Figure D Alarm "Span adjustment load imbalance" is displayed. Check if only one tension detector is connected. The alarm displayed is for confirmation, not an error. Left and right polarities differ on the sensor input voltage monitor. Match the polarity of the left and right tension detectors.
