Functions
Error Detection Function
Overview :
Mechanism for detecting press fit failure
By combining a load cell (load sensor), an AC servo motor (electric drive), and a ball screw, load and position data (stroke) can be captured, enabling various control.
The stroke speed, position, and load are arbitrarily set to perform press-fit operation and judgement.
Judgment is made in real time while monitoring changes in load and position (stroke) during press-fit operation.
Therefore, it is possible to detect errors such as galling.
Description :
【Note】 Position and Distance
Position: Travel distance measured from the machine origin
Distance: Travel distance measured starting from the specified load
Load :
End load determination
It is controlled by the load, and the load and time/position are judged at the end of press-fitting.
Check that the press fit has been performed normally.
Judgment of this load and time/position is the basis.
Monitor 3 :
Load zoning judgement (MPU60 only function)
Continuously monitors the upper and lower limits of the load in any position range (zone) during press-fit operation.
Defects such as improper press-fit load, galling, misalignment, and prevention of damage to the workpiece can be detected.
Peak-load judgment (MPU60 only function)
Detects the peak load in the zone of measurement position and load during press-fit operation.
Poor judgment of bottom hole/part tolerance is possible.
Interval monitor judgment
Monitoring is performed during press-fitting, and continuous monitoring is performed.
The OK zone of the load and position (distance) is set as the set value, and NG judgement is made for the load deviated from it.
Determination of missing load, misalignment, or misalignment is possible.
Back monitor judgment
Judgement is made after completion of press-fitting.
The OK zone of the load and position (distance) is set as the set value, and NG judgement is made for the load deviated from it.
Determination of missing load, misalignment, or misalignment is possible.
Determination of inflection point monitor
Detects the inflection point of the press-fit curve during the press-fit operation.
The amount of load change is judged in the zone of inflection point position and load.
It is possible to judge caulking failure or missing load failure.
Memory Feature Contributes to Traceability
Various data related to pressurization, such as pressurization results, pressurization curves, and system error history, can be saved, thus contributing to traceability.
Pressurization parameters can be rewritten from Fieldbus
99 types of pressurization parameters are available to flexibly accommodate the set values requested by the customer. For those who want to set the parameters more freely, a function to rewrite the pressurization parameters from Fieldbus is also available.
Network
Communication Technology
ESTIC’s servo press is equipped with a platform that can easily communicate and integrate with host systems through open protocols, etc. Production-efficiency and quality-improvement can be realized by configuring assembly lines mainly for ESTIC’s servo press.
Management Software
This is the dedicated support & management software for all ESTIC’s Servo Press controllers.
Basic as well as advanced management functions of ESTIC’s Servo Press are supported : Read/write parameters, project data storage & management, Pressurization result & curve monitoring,
I/O & Fieldbus signal assignment, and more.
