Tension detector input
The tension detector that has been used with the LE-30CTN(A) can be used as it is. A strain gauge type load sensor can also
be used with the LE7-40GU-L.
Analog input
When it is used for general-purpose input, function assignment is required (same as the LE-30CTN(A)). The voltage range
can also be switched in the LE-40GU.
For details of function assignment in each operation mode, refer to the following.
LE7-40GU-L APPLICATION MANUAL
Analog output
When the LE-30CT mode is selected in the initial setting mode, function assignment is performed as follows: the AO1 terminal
is assigned to the tension monitor and the AO2 terminal is assigned to the tension setting monitor. When the LE7-40GU-L
mode is used as it is, the AO1 terminal is assigned to the tension monitor and the AO2 terminal is unassigned.
For details of function assignment in each operation mode, refer to the following.
LE7-40GU-L APPLICATION MANUAL
Contact input
Since LE7-40GU-L has the sink/source switching function, it is recommended to use sink wiring when replacing from LE-
30CTN(A). Note that stall memory and output gain operation are different.

LE7-40GU-L APPLICATION MANUAL
Contact output
The LE-30CTN(A) uses a relay output, but the LE7-40GU-L has been changed to an open collector transistor output. When
ZT (zero tension detection output) is used, pay attention to the power supply (AC, DC) and current direction after replacing to
the LE7-40GU-L.
