1. Outline
The LE-30CTN tension controller receives signal from the LX-TD or LX-TD-909 tension detector to
automatically control the tension of the long material at the unwinder, feed reel, and winder. This controller
therefore generates a control voltage of 0 to 24 V to control the powder clutch/brake and the hysteresis clutch/
brake, or generates the torque command voltage of 0 to 5 V to send to the servo amplifier
1.1

Features

1) The menu function enables storage and reading of 8 types of operation data.
2) The optional memory cassette enables reading of operation data and writing of data in the other LE-
30CTN tension controller.
3) The controller has a weak excitation function for the powder clutch/brake. This function will improve the
torque rising operation in low-speed operation mode or during the initial start-up of machine.
4) The controller automatically judges the polarity of the detector signal, therefore, wiring is performed with
ignoring the specification (compression or tension).
5) The dot matrix type liquid crystal display is adopted for this controller, it has the capability of displaying
Chinese characters.

use
The external units shown in the above figure can be connected to the input/output terminals of this
tension controller. The tension detector, actuator, and some command input switches (white-black
inverted characters) should always be connected. However, connection of other units is not always
necessary.
