The Principle and Fault of the Servo Press Are Complete

Servo presses are usually referred to as presses that use servo motors for drive control. Including metal forging servo presses and refracing materials and other industries dedicated servo presses. It is a new type of press driven by servo technology to realize the metal stamping forming process, which is generally simply powered by servo motor, and the stamping machine driven by servo control circuit system is called servo press. Servo stamping also includes this servo press equipment and servo-controlled stamping process.

The number of swings of electric motors (general motors) frequently used by general machinery is determined by the number of poles (2 poles, 4 poles, etc.) and the number of weekly waves of the power supply (50Hz), and must be achieved by another electrical or mechanical variable speed device. If the variable speed device equipped with ordinary motor-driven to change the speed of the universal press, that is, the growth time of the press fly wheel from stationary state to full-speed operation even small press takes tens of seconds, large press takes a few minutes. It is not possible to triple the number of swings of a fly wheel in a swing to ten seconds to tens of seconds, and to increase or subtract the speed 10 times within 1min during stamping.

However, servo motors have the ability to run from stop to full speed only 0.1 to 0.5s, if the electronic control design is appropriate, in 1min can be reached dozens of times. If the amount of change in speed is relatively small, servo motors can make it possible to change speed more frequently, that is, servo motors are motors that respond "faithfully" by CNC circuits. Servo motor with correct speed control and angle control, are in the swing speed, swing angle, swing direction and swing force (torque) under the command of the action, the result of the action and the command value after the calculation comparison, and then feedback to the instructions issued, and then the result re-calculation and then issued the next instruction, so, in the command value and result comparison swing drive, and is used to the necessary place.

The servo motor on the CNC servo press is controlled by the comparison of instructions and results. The CNC servoization of the press is a device that is calculated by the high reliability of the servo motor and the command value occurrence device, the position and force value detected by the sensor (also known as the encoder) and the difference between the command value, plus the power output device of the motor voltage, current or wave number of the week, and the increase device of the command value.

Problems.

.1 Interface parameter setting problem.

1, Q: process parameters inside want to fast-forward speed, return speed set a larger point why not set?

A: In general, this situation is to set-protect the parameters inside the speed protection, such as detection speed, press speed, motion speed and so on. All you need to do is release these protection parameters to a reasonable value.

2, Q: debugging, there is a negative limit trigger alarm, but the negative limit switch is not triggered, what is the reason?

A: This is because the current position of the motor triggered a soft limit, in the setting-protection parameters inside the soft positive limit and soft negative limit, if the alarm is triggered, the need to use debugging mode, the head will return to the normal range, press the reset button to return to normal.

Q: When the zone detection settings, the zone start value cannot be set to a larger, feel limited?

A: Because the zone start value must be less than or equal to the zone end value, if the re-set zone start value is greater than the previous zone end value, you cannot set it, you need to set the zone end value first, and then set the zone start value. This is the same when the window detects the Window Start Value and the Window End Value.

Q: Ready to shut down, file management is saving mold files, incorrect "file name error"?

A: This is because the mold name was not selected correctly. At this point, you need to re-click on the stencil parameters you want to save, see the "file name" column shows the name, then click on the save symbol, pop up whether to overwrite the dialog box click OK to save successfully.

Q: The system time in the upper right corner is incorrect, resulting in incorrect report time recording, where to modify it?

A: Configuration - system settings - system time, after modification, click the confirmation button to update the time. If not, it may be that the button battery is powered out and needs to be replaced with a new battery.
