Mitsubishi digital tension controller ld-30FTA
* MITSUBISHI DIGITAL TENSION CONTROLLER LD-30FTA
* INPUT VOLTAGE: 85V-240V 50/60Hz
the type LD-30FTA tension control unit is an open loop type semi-automatic tension control unit adopting
the reel diameter calculation control called "integrated thickness detection method".
In the integrated thickness detection method, the initial diameter and the material thickness are preliminarily
set in the control unit, and the current reel diameter is calculated by subtracting (for unwinding) or adding
(for winding) the material thickness multiplied by the number of rotations of the reel bobbin shaft from/to the
initial diameter. (A proximity sensor is provided in the reel shaft so that the number of rotations can be detected.)
The calculation result is used to generate the voltage output of 0 to 24 V for a powder clutch/brake or hysteresis
clutch/brake functioning as an actuator or generate the command voltage of 0 to 5 V for an amplifier
The tension control is possible by an easy adjustment and the operation.
Automatic control is possible only by the tension setting and setting a thickness of the material and an
The input power supply is wide range of 100 to 240VAC.
A material thickness and an initial diameter can be widely set.
The reel diameter can be memorized even if the power supply is turned off.
Many kinds of actuator which is the AC servo etc.
Advanced mode which supports various situations.
Inertia compensation function at accelerating and decelerating mode.
Compensation function for non-linear torque of powder clutch/brake.
Mechanical loss compensation function .
English/Japanese display and pictograph display
Numeric setting by dial operation
Pleasant operativeness by eight kinds of material memories
The drive constant (thickness of the material, initial diameter, and taper rate, etc.) can be memorized
Adoption of locking key to prohibit miss-operation prevention and display of invalid function.
The ultrasonic sensor and the touch lever can be used.
The use of the ultrasonic sensor and the touch lever becomes possible by installing analog input board
As a result, the operator becomes possible the automatic operative method only because of the tension
setting according to an analog volume.
It is the best for such a control.
Machine which does not need tension accuracy so much.
Machine which moves slightly though the material is not heavy.
