3 TRANSITION FROM LE-30CTN(A) TO LE7-40GU-L
3.2 Comparison of I/O Terminal Blocks
Terminal specifications
Since the terminal type changes from a screw type terminal to a spring clamp type terminal, stranded wires and bar type crimp
terminals are used for wiring. Therefore, when using a round terminal and Y terminal, terminal processing of the wiring is
necessary.
Tension control output for powder clutch/brake
After replacement from LE-30CTN(A), the same function as before replacement can be used by selecting the LE-30CT mode
in the initial setting (operation mode selection).
Control output signal
After replacement from the control output of the LE-30CTN(A), set the motor tension control output to 0 to 5 V and use it. For
LE7-40GU-L, it can also be set to output as for motor control.

detector
Input GRL Left Connect the lead wires GR=green (blue) and
WH=white of the tension detector inputs.
When only the detector on one side is used, it is
necessary to make a short circuit between GR and
WH on the other side.
The compression/tensile load is determined
automatically.

• Input range switchable
(1) -150 to +150 mV DC (LX tension detector)
resolution: Approx. 7.90 V
(2) -15 to -15 mV DC (strain gauge) resolution:
Approx. 0.790 V
