<in case of ELIO operation mode>
Please note torque value displayed on initial screen of keypad, setting
manual operation speed command as ‘0’.
In order to show torque value on keypad, please set value as “Trq Output”
on E/L_58(Display Sel).
With data estimated above, a line as show below can be made. And with an equation, setting
values can be obtained.

A straight line equation
If expressing a straight line passing through two points above, y=A*x + B can be displayed. In
this case, A is the slope and details of it are as follow.
A=(during up operation, torque capacity – during down operation, torque
capacity)/( during up operation, AI1 value – during down operation, AI1 value)
If calculating y-(during no load down operation, torque capacity) = A*(x – during no load down
operation, AI1 value),
B=(
during no load down operation, torque capacity
) – A*(
during no load
down operation,
AI1 value)
<Calculation Example>
A= [100%-(-100%)]/(100%-0%)= 2
Therefore, y-(-100%)=2*(x-0%), B=[-100%]-2*[0%] = -100%.
If changing to a form of, y=A*x+B, y=2*x-100%
