0.1Hz, main motor stepless speed regulation work；Single 1 external control, frequency converter working frequency is analog input, and setting is inaccurate；It is single
2 Communication Controls, when communication is interfered, frequency converter job insecurity, peripheral operation is uncontrollable, there is potential safety hazard, this
The accuracy that scheme of the invention had both solved frequency converter setting in turn ensure that the security of peripheral operation.
（3）Tonnage instrument data processing and control is integrated in PLC and touch-screen, sets simpler, shows apparent, tonnage instrument
4 groups of tunnels analogy values are linked into tonnage detection functional module, and the sensor of 4 groups of tunnels analogy amounts is respectively arranged in forcing press
Aditus laryngis column inner side at 4, the change of real-time detection forcing press blanking pressure, at data of the PLC by internal processes to collection
Reason, shows data by RS232 communication modes in real time in touch-screen, can understand each position of lathe with open-and-shut
Bear pressure；The alarming value that client can be according to operating mode setting per passage simultaneously, such as left front column alarming value is set as
200T, after forcing press works once, it is 220 to detect the measured value of left front column, more than the alarming value 200 of left front column
When, forcing press is stopped immediately, and the alarm red led at forcing press left front column position is bright, facilitates client to immediately find
Trouble location is simultaneously overhauled, and enhances man-machine flexibility operation.The present invention can be used in hot forging production technology.
