Product outline

PFA is an all-purpose type controller that can perform motor control & OK/NOK judgement at the same time!
Sequence can be setup with easy touch panel operation while changing test condition.
Various judgement functions such as waveform judgement by 2 dimensions including “Force vs. Displacement” or “Torque vs. Angle” are mounted, which manages tests inclusively.
Can be cooperated with external peripheral devices & can perform continuous tests independently, thus can construct testing device, pressing machine & screw tightening device etc. without PLC.
Enables high speed press without overshooting.

Application

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.
Press behavior can be decided by inputting speed, position, and other parameters.

Screw tightening management template compliant to torque method & turning angle method is also available.
Can be used as controllers for tension & compression test machines, bending testing machine & endurance test machine as well.
