<p>A control device for motor torque reduction of a winding/unwinding unit for flexible elements comprising: an electric motor (2) electrically connected to a first condenser (9) operable in both rotation direction, coupled with a reduction unit (12) connected to a winding/unwinding roll (11) of a flexible element, an encoder (16) mechanically connected to said reduction unit, a logic unit (26) comprising memory means (26a) and counting means for the number of impulses coming from said encoder, able to elaborate said impulses and to send control signals to said motor torque reduction means, said logic unit programming means (13, 14) and actuator means (13) to activate said motor. The device is characterized in that said torque reduction means are operated by said logic unit when the number of impulses computed by said counting means is equal to a number previously set in said logic unit memory means (26).</p> |
