When adjusting and inspecting products equipped with a servomotor, recording of the servo output waveform is indispensable. The servo pack's speed waveform and torque waveform can be observed and recorded with a MEMORY HiCORDER. It is desirable that the torque
characteristics are uniform during all operation modes.
Overshooting and waveforms with blunt rise edges are undesirable. While the MEMORY HiCORDER is used to observe the speed and torque waveform, the servo pack's speed loop gain can be adjusted until uniform torque waveforms are obtained.
Furthermore, in the case of industrial robots where multiple servomotors are employed, each of the control signals and feedback signals can be simultaneously observed and recorded.

As the arc length is proportionate to the arc voltage, the arc welder's voltage and current waveforms can be monitored to see if they are within specifications and by employing the FFT analysis function, the deviation of each weld can be understood.
The current waveform can also be observed to check the quality of welding in the case of contamination of material surface, dimensional variations, etc. to ensure stable and reliable quality control.

When installing a machine, the strength of material bodies can be increased by ensuring that the natural frequency of the machine does not coincide with the vibration frequencies of the surroundings.
Example: After striking the machine (object to be measured) with an impulse hammer, the propagated signal is captured by acceleration pickup sensors and the transfer function can be found to determine the machine's (object) natural frequency (x ? x' Hz).
By shifting the natural frequency of the machine (object), resonance can be suppressed to reduce noise and vibrations.

Pressure waveforms can be measured and recorded simultaneously at various points of hydraulic machines to determine whether such machines are operating normally. The scaling function allows the user to directly read pressure values.

New stepper motor drive methods, such as the micro-step drive method, have come into use. Using the MEMORY HiCORDER's waveform evaluation function, the waveform of the motor control signal, which is output from the controller, can be checked to judge whether the controller is conforming to specifications.
The waveform evaluation function can also be used for inspection and evaluation of controllers operating according to standard control methods, provided that waveforms can be used to check whether or not the controller is operating according to specifications.

The injection molding machine's 1-cycle operation command signal, the pressure and displacement can be recorded. In addition, torque, current and voltage, etc.
can also be recorded.
This data can be repeatedly recorded using the X-Y recorder or the overwriting feature of the memory recorder function. By repeating this and monitoring the operation, it is easy to conduct performance variation checks and quality inspection.

Compressor shaft torque irregularities adversely affect coupling reduction gears.It is difficult to detect instantaneous torque irregularities by merely surveying the motor's load current. Strain-gage sensors with FM transmitters should therefore be attached to the shaft.
Since it is impossible to predict when irregularities may occur during operation, trigger functions can be used with advantage to record the time when irregularities occur in the form of a time chart. This makes it simple to analyze the cause of the problem. In the case of processes
utilizing a roller, the trigger functions can also be used for monitoring the roller's rotating speed, control timing, and to check whether items fall within specifications.
