The first step is the design of the frequency conversion system. The pfx525 frequency converter is used to drive the motor to realize the precise control of the forward, reverse, speed adjustment, stroke and positioning of the lead screw slider. Finally, through the connection and communication between the force control configuration software and micro850 PLC, the control system is adjusted online, and the emergency stop switch is added to the force control screen to avoid the safety problems caused by the system failure. The communication mode selected by the frequency converter system is. The controller is connected with the force control configuration software to realize the data transmission of the whole system.
