Basic Wiring; Wiring Of Tension Detector - Mitsubishi LE-30CTN Instruction Manual

2. Installation and Wiring
2.2.2

Basic wiring

• To control the tension using the LE-30CTN tension controller, perform at least the following wiring.
[1] Connect the AC power supply line of 100 ~ 240 VAC and 50 / 60 Hz between terminals L and N.
When maximum output between PP and PN is readed, the power consumption will be 400 VA.
• Do not connect any 380-VAC power line to the power supply terminals [L] and [N]. The product
may be seriously damaged.
[2] Perform grounding (grounding resistance 100Ω or less) to the grounding terminal and the metal plate.
[3] Connect the tension detector.
[4] If the powder clutch/brake or the hysteresis clutch/brake is used, connect the actuator between
terminals [PP] and [PN]. If the rated current of the powder clutch/brake is 3 A or more, connect the
[TOUT] - [AOC] signal line to the input terminal of the power amplifier that is optimum for the rated
current of the powder clutch/brake, and connect the powder clutch/brake to the output terminal of the
power amplifier.
If the torque controllable servomotor is used, connect the [TOUT] - [AOC] signal line to the torque
command terminal of the servo amplifier.
[5] Connect the start/stop signal line to the [RUN] and [MIC] terminals.
Caution:To perform automatic operation, be sure to turn the [RUN] input signal OFF and
• To use various functions, refer to Sec. 5 and subsequent sections.

Wiring of tension detector

[1] While ignoring the loading direction (compression or pulling), connect the cable of the tension
detector as shown in the above figure. The loading direction will be automatically detected.
[2] If only one tension detector is used, short-circuit the unused line between the input terminals ( [GRR]
and [WHR] or between [GRL] and [HWL] ).

ON according to the machine operation status (run or stop).
If this signal is kept at the ON status, restarting the operation of the stopped
machine may apply extremely strong tension to the material, and the material may
fracture.
