The standard / continuous cycle time indicates the time required when operating with the fastest round-trip operation setting under the following conditions.

Transfer mass of 2kg, vertical movement of 25mm and horizontal movement of 300mm (coarse positioning arch motion)

[Standard cycle time]

The time required for the fastest operation. Generally, this is a guide for high-speed performance. Please note that continuous operation at the fastest operation is not possible.

[Continuous cycle time]

The cycle time for continuous operation.

During operation, use the following restrictions as a guide for the horizontal and vertical dimensions from the tip of the spline. If the load offset is large, it may cause abnormal noise or vibration, malfunction, or shorten the service life. Adjust the speed and acceleration / deceleration as appropriate, or adjust the balance of the center of gravity. The overhang length is limited based on the load and operating conditions.

SCARA Robot IXA cannot operate continuously at the maximum acceleration / deceleration and maximum speed noted in the catalog. When operating at the maximum acceleration / deceleration, set the stop time by referring to the guideline graph of continuous operation duty. If continuous operation is required, operate it under a setting within the range indicated in the continuous operation guideline of the guideline graph for acceleration / deceleration setting.

(1) In case of PTP operation, be sure to use the WGHT instruction on the program to set the mass and moment of inertia before operating. For SCARA, 100% is defined as the maximum acceleration/deceleration that can be operated at each payload. Please note that the operating time varies based on payload even if the acceleration/deceleration and speed settings are the same.

(2) Adjust the acceleration / deceleration by gradually increasing the set value from the continuous operation guideline value.

(3) If an overload error occurs, reduce the acceleration / deceleration as appropriate, or make adjustments to set a stop time by referring to the guideline for continuous operation duty.

(4) Duty (%) = (Operating time / (Operating time + Stopping time)) x 100

(5) If you wish to move the robot horizontally at high speed, move the vertical axis as close to the rising end as possible.

(6) Keep the moment of inertia and payload below the allowable values.

(7) The payload indicates the moment of inertia and mass of the center of rotation of the 4th axis.

(8) Operate the robot with an appropriate acceleration / deceleration based on the mass and moment of inertia. Failure to comply will result in early life, damage and/or vibration of the drive unit.

(9) If the moment of inertia of the load is large, vibration may occur at the vertical axis depending on its position. If vibration occurs, slow down the acceleration / deceleration as appropriate.
