Title:
SIGNAL SETTING DEVICE
Document Type and Number:
Japanese Patent JPH03273401
Kind Code:
A
Abstract:
PURPOSE:To extend a set range by adding/subtracting a moving quantity portion only in a direction parting from a reference position to/from the count value of a reversible counter when a setting element moves in a second moving area apart from the reference position. CONSTITUTION:When a set lever 12 is in a first moving area involving a refer ence position 0, that is, a count value (c) of a counter output is between +1000 to 0 to -1000 for instance, the count value of a reversible counter is increased/ decreased corresponding to the moving direction of the set lever and a correcting output dc is made with the number of count increasing/decreasing as it is. When the output (c) becomes +1010 to +1005, since it is the direction to get near the reference position 0, both the outputs dc and (e) are held and are not subtracted. On the other hand, when the output (c) moves +1005 to +1006, that is, the direction apart from the reference position 0 again, the outputs dc and e are added with considering also a correcting coefficient. Thus, high accurate setting over a wide range is attained with a simple operation.
