1.1 Outline of unit

The tension controller LE-40MTB-E automatically controls the tension of a long material during unwinding,
use of the feed reel and winding, and is used together with the fine displacement tension detector.
The applicable actuators are powder clutch/brake, hysteresis clutch/brake, servo motor (torque mode), and
air clutch/brake.
• The operator can make various settings including the operating constants such as for tension and man-
ual torque, and the mechanical constants for reel diameters in a similar manner to operate a volume
controller with the pulser dial on the panel.
• Functions such as auto-zero adjustment and span adjustment of the tension detector and the automatic
adjustment of control gains for automatic control are also available.
• The operation data can be read or write using the optional memory cassette.
• Menu selection from "0" through "7" on the panel allows the operator to select and use eight kinds of
operation data.
• The tension controller can be connected to the CC-Link interface unit, and also equipped with a paralled
link function with FX2 siries programmable controller.
• If connected to the optional LE-40MD reel diameter calculation unit, it performs precise taper control to
prevent the material from being wond too tight.
