Technical InformationExplanation of TermsCleanlinessGrade of cleanliness for cleanrooms according to ISO standard. ISO class 4 (equivalent to US FED STD class 10) indicates an environment in which there are fewer than 10 pieces of debris 0.5μm or smaller per cubic foot.CouplingA component used as a joint to join a shaft to another shaft. e.g. The joint between the ball screw and the motor.Creep sensorAn optional sensor to allow high-speed homing operation.Critical speedBall screw resonation with slider speed (No. of ball screw rotations). The maximum physical speed limit that can be utilized.CW (Clockwise rotation)Abbreviation for clockwise rotation.It describes a rotation to the right, as viewed from above, i.e. same as the rotation of a clock's hands.Cycle timeThe time taken by one process.DispenserA device that controls the flow rate of a liquid. This is integrated into devices for applying adhesives, sealants, etc.DutyIndicates the work ratio in the equipment industry. (e.g. The time that the actuator operates in one cycle.)Dynamic brakeA brake that uses the motor's regenerative energy.EncoderA device for recognizing the RPM and the direction of a rotation by shining a light onto a disc with slits, and using a sensor to detect whether the light is ON or OFF as the disc is rotated. (i.e. a device that converts rotation into pulses.) The controller uses this signal from the encoder to determine the position and speed of the slider.Incremental A-phase slitLight-receiving elementAbsoluteLight-receiving elementB-phase slitLight-emitting elementZ-phase slitSlitLight-emitting elementAn incremental encoderdetects the rotational angle and the RPM of the axis from the number of output pulses. To detect the rotational angle and the RPM, a counter is needed to cumulatively add the number of output pulses. An incremental encoder allows you to electrically increase the resolution by using the rise and fall points on the pulse waveform to double or quadruple the pulse generation frequency.An absolute encoderdetects the rotation angle of the axis from the state of the rotation slit, enabling you to know the absolute position at all times, even when the rotating slit is at rest. Consequently, the rotational position of the axis can always be checked even without a counter.In addition, since the home position of the input rotation axis is determined at the time it is assembled into the machine, the number of rotations from home can always be accurately expressed, even when turning the power ON during startup or after a power outage or an emergency stop.Excess voltageVoltage applied to motor that exceeds regulation value when commanded speed is too fast.External operation modeThis is the operation mode started by a start signal from an external device (PLC, etc.). This is also called automatic operation.Flexible hoseTube for SCARA Robot MPG cable that the user passes wiring through.Appendix: - 19 Technical Reference/Information
