Non-Linear Compensation - Mitsubishi Electric LE-50PAU Instruction Manual

5.2 Non-linear compensation

1. Non-linear characteristic
The exitation current vs. transmission torque character-
•
istic of clutch / brake is of non-linear characteristic as
shown at right, and may be different, depending on the
type name of each clutch / brake.
Set the transmission torque value at 10%, 20%, 40%
and 80% current for non-lineare data.
In this case, "100%" current is a rated current of clutch /
•
brake, and "100%" torque is a transmission torque at
the rated current, and is greater than the value of nom-
inal torque of clutch / brake for new product.
The following shows a setting example based on the ex-
•
ample shown in the drawing at right.
The practical clutch / brake setting value is as shown in
the list given no the page 21,22.
2. Setting procedue
When the [INC ] key or [DEC ] key is pressed, the numeric value displayed is increased or de-
•
creased.
When the key is kept pressed, the numeric value is incerment or decrement at high speed automatically.

When it is not necessary to change the numeric value, press the [SET] key as it is, by which the step
•
is advanced to the succeeding step. The last step is resumed each time when the [MODE] key is
pressed.
When the MODE key is pressed with the SET key
SET MODE
pressed, the non-linear data setting mode is turned on .
When the same operation is performed again , the mode
is reset and the output display mode is serumed .
