Correlation diagram between payload and speed

■ Pulse motor equipped model A4 (G)

Due to the characteristics of pulse motors, the payload capacity decreases as the speed increases.

Check the table below to see if your desired speed and load capacity are met.

X-Axis

Please refer to the table below for the acceleration/deceleration settings.

Y-Axis

The set acceleration/deceleration should be 0.4G or less.

Z-axis

The set acceleration/deceleration should be 0.2G or less.

Payload capacity and acceleration/deceleration

Payload capacity Acceleration/Deceleration
20kg 0.2G or less
18kg 0.2G or less
15kg 0.3G or less
12kg 0.3G or less
10kg 0.4G or less
8kg 0.4G or less

International Standards

(Note) CE is only compatible with safety category specifications.

Selection considerations

(1) The maximum acceleration/deceleration varies depending on the payload. (See "Correlation diagram of acceleration/deceleration and payload.") Also, stepper motors cannot reach their maximum speed at the maximum payload setting. Increasing the speed reduces the payload. Please note that the rotating axis cannot reach its maximum speed depending on the load moment of inertia value. (See "Correlation diagram of payload and speed" and "Correlation diagram of R-axis allowable load moment of inertia and angular velocity.")
(2) Repeated positioning accuracy is only valid when the body temperature is constant. Absolute accuracy is not guaranteed.
(3) The dynamic allowable moment values ​​are for each axis. For a standard rated life of 5,000 km and a standard load factor of 1.5. (For details on dynamic allowable moment, see page 5-692
.) (4) In the model item, enter "E" in the expansion I/O slots 1 and 2 columns if they are unused.

*1 When placing a workpiece on the X-slider, make sure there is a clearance of 2 mm or more from the main frame.

*2 When the cover option (model: CO) is selected, a cover will be attached to the front of the Z-axis to hide the slider.

(Note) When performing origin return, the slider will move to the ME, so please be careful not to interfere with the surroundings.
