1.1 Outline of unit

The tension controller LE-40MTA-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 tension setting and the manual operation torque usually used by the operator can be adjusted
easily using the trimmers provided on the panel.
• The diversified system parameters and operation parameters which must be set by the engineer before
operation can be set using the NUMERIC INPUT (increase/decrease) keys while checking the LCD
display provided on the panel.
• The automatic zero adjustment function and the span adjustment function for the tension detector as
well as the automatic control gain adjustment function for automatic adjustment are offered.
• The operation data can be read and written using the memory cassette FX-EEPROM- 4 (or-8) sold sep-
arately.
