<<<<提醒：左右滑动表格>>>>| sports event | Performance Judgment Basis | ||
| A | B | C | |
| General Product Performance | No significant change in operating characteristics. Within specified tolerances Normal operation | The operating characteristics are obvious (visible). or audible) changes. Self-recovering | Shutdown, change in operating characteristics. Protection Device Trigger. Cannot recover on its own |
| Special torque characteristics of the drive | Torque deviation within specified tolerances | Dynamic torque deviation exceeding the specified tolerance. It's self-recovering. | Torque runaway. Cannot recover on its own |
| Subcomponent performance: Information processing and detection functions | Communication and exchange of data with external devices without harassment | Temporarily harassed communications, will not be sent. The following may be caused by an external or internal device Setting the shutdown error report | Communication error, data or message Lost; Cannot recover on its own; and No loss of saved programs; and No loss of the user's program; and No loss of system or device settings |
| Display and control panel operation | No change in on-screen information, only It's a slight fluctuation in brightness or a slight change in character. | Information may change temporarily, screen Unsatisfactory curtain brightness | Shutdown, lost or abnormal information The way it works, the information displayed is clearly incorrect. No loss of saved programs; and No loss of the user's program. No loss of system or device settings |
| Acceptable Performance Criteria A, B, C: False start is an unanticipated change of the product from the logical state "STOP". If the motor is not running at all, it may cause the motor to run. | |||
