Use Of External Analog Signals; Varies Set Tension; Enters Reel Diameter Data - Mitsubishi LE-40MTA-E Instruction Manual

8. Use of external analog signals

When entering settings externally by analog voltage, prohibit the settings change from the panel. This
makes the setting value change only by the external analog input (controller installed externally) valid.
Regarding the tension setting , stall setting, new reel presetting and taper ratio setting , the
setting through the panel or the setting by external analog input , whichever is greater , takes
precedence in shipping -setting condition . By prohibiting change of the setting value from the
panel on the "Setting prohibited " screen, only the external analog input (controller installed
externally ) is made valid.
If prohibited to change setting value from the panel , the setting value from the panel will be fixed
at the value immediately before the prohibition .
1. Setting
To set setting prohibition, use the "INH.ENT." screen within "OTHERS" on the engineer screen.

8.1 Varies set tension

1. Connection
• Instead of setting the tension from the panel, input signal of
0 to 5V can be used for the tension setting.
When the input of 0 to 5V is given the tension setting value
becomes 0 to 100%.
• Connect the signal to the terminal A11 as per the figure at
right.
The tension setting from the panel or the tension setting by
the external input, whichever is greater, becomes valid. See
the notes above.

8.2 Enters reel diameter data

Refer to page 30 Section 7.4 "External reel diameter taper control".

If "Stall set" prohibition has made valid, the stall setting change
from the panel will be prohibited . The setting value will be fixed
at the value immediately before the prohibition .
If the external analog input is valid , message "EXT." appears on
the "Tension set" screen as shown below. If "EXT." is gone, the
key setting is greater and is therefore valid .
