Abstract (en)

[origin: EP0732194A1] A high speed press has an upper plant Ä2Ü to which is fixed the top tool Ä3Ü of a die-set and is moved by a motor with a transmission Ä9Ü. Attached the platen is a magnetically coded rod Ä7Ü that consists of alternating segments of magnets that alternate in polarity. Mounted on a fixed support Ä17Ü is a detector head Ä12Ü. As the rod moves relative to the detector ac voltage pulses are induced in a coil within an electronic control unit Ä13Ü. Motor motion is monitored by a position transducer. The distance moved is continuously compared with a reference value to control the lower dead point of the tool movement.
