DIFFERENCES IN FLOW AT MACHINE
STARTUP ADJUSTMENT
This section describes the differences in flow at machine startup adjustment.

Differences in Operation Flow

An operation flowchart is shown below. There is no difference in the basic operation flow till the test operation among LE-
40MTA, B(-E), LE-30CTN(A), and LE7-40GU-L.

Difference in Operation Mode

LE7-40GU-L has the following operation modes.
Mode Explanation
Initial setting mode Initial setting mode at startup of equipment
Adjustment Mode Parameter detail setting mode
Operation mode Yes
Initial setting mode
• The LE7-40GU-L has an initial setting mode and is set in the initial setting mode from the factory shipment until the initial
setting completion operation is executed. In the initial setting mode, the setting items that are indispensable for the
operation of the tension controller are set in order. The LE-30CTN(A) does not have a function corresponding to the initial
setting mode.
• The items that can be set in the initial setting mode differ between LE-40MTA, B(-E) and LE7-40GU-L. The parameters that
can be set in the initial setting mode are compared below. The parameters that can not be set should be changed in
adjustment mode.
