Abstract
The invention discloses a PLC control program of a double-motor asynchronous-starting type hydraulic press. The double-motor asynchronous-starting type hydraulic press comprises a starting button, a stop button, a motor I indicator lamp, a normally open contact of the motor I, a timer I, a timer I state output point, a motor II non-starting normally closed contact, a motor II indicator lamp, a starting state output point, a stopping point state output point, a timer II, a motor II non-starting normally open contact, a timer II state output point, a motor II non-starting indicator lamp. The PLC control program comprises the following steps: a, quickly pressing the starting button to switch on the motor I indicator lamp, namely starting the motor I and starting the motor II 3 seconds later; b, pressing the starting button for 2 seconds, and not starting the motor II. The PLC control program of the double-motor asynchronous-starting type hydraulic press has the characteristics of being simple in structure, reasonable in starting time setting, strong in program logicality and adjustable in timer setting.
