Use Of Cut Torque; Reduction Of Variation In Tension Readout - Mitsubishi LE-40MTA-E Instruction Manual

7.10 Use of cut torque

In the automatic paper-jointing control, this func-
tion facilitates the material cutting while the cut-
ter is in operation by fixing material tension at a
greater value.
When the MC5 or MC6 contact input is ON, the
control output is fixed and maintained at a con-
stant level.
The lower limit of the control output is limited to
the cut torque setting value.
When the reel change signal is entered, the val-
ue changes to the new reel preset value.
The reel change signal takes precedence over
the cut torque. However, turn off the cut torque
before the new reel preset timer times up.
1. Connection
• Use a micro signal switch commensurate with DC8V 4 mA as the
input contacts.
• Connect the cut torque to the terminal MC5 or MC6 set as follows.
2. Setting
• Use the "MC5" or "MC6" setting screen within "SWITCH" on the initial setting screen or the engineer
screen to set or change the cut torque setting.

7.11 Reduction of variation in tension readout

To reduce variation in the tension readout, select "Display filter" within "Tension" on the engineer screen.
Increase the value to make the response slower. This makes the tension reading more stable and com-
fortable when it varies quickly.
