PFA
PRESS FORCE ANALYZER
Product outline
PFA monitors press process by waveform
DO NOT miss NOK workpieces
Servo motor controller is equipped. Even beginner of motor control can create simple sequence by using touch panel setup.
Features
OK/ NOK judgement with 2 sensor inputs
Two-dimensional OK/NOK judgement can be performed with force (Y axis) and time/ displacement (X axis)
Comparison & hold function from waveform display
Reputable judgement algorithm of F381A and FS2000 is programmed.
■Waveform comparison judgment
The function compares the actual measurement waveform against the setup High/Low limit waveforms.
It will give out an NOK judgement when any of the point exceeded the present High/Low limit waveforms.
■Multi-point judgment
OK/NOK judgement can be performed on multi points in one process. (e.g. The start point and end point of press fitting can be judged respectively.) (Max. 5 points)
Easy for communication with a host
Results and waveforms can be uploaded to host over the network.
Also, judgement switching and monitoring can be done remotely from the host.
Measurement data and set values can be recorded into SD card.
Preventive maintenance with trend display
Can detect abnormalities quickly & prevent malfunction by using trend display to monitor changes of zero point, hold values, etc.
Using master as reference, you can see directly the difference by comparing to a commissioned machine.
Motor control function
Motor control uses versatile pulse input/output.
Compatible with various motors.
Templates are available for frequently used sequence.
Easy to setup. Just input setting values of speed, position, etc.
