代码 SRVO-281: SVOFF input(SVEMG abnormal)

Cause: When the SVOFF signal was asserted, an SVEMG error was detected. The emergency stop circuit is faulty. Remedy: If the RDY LED (green) is lit: 1. Check the switch and cable connected to 9 (EGS1) - 10 (EGS11) and 11 (EGS2) - 12 (EGS21) on operator panel terminal TBOP4. 2. Replace the panel board. 3. Replace the EStop unit. 4. Replace the servo amplifier. 5. Replace the connection cable between the EStop unit and the panel board. If the RDY LED (green) is not lit: 1. Replace the cable connecting between the main board (JRS11) and the panel board (JRS11). 2. Replace the panel board. Note: Before executing the next step, perform a complete controller back-up to save all of your programs and settings. Failure to perform this task could result in damage to the equipment or lost data. 3. Replace the main board. Note: If the SYST-067 Panel HSSB disconnect alarm occurs simultaneously or the RDY LED is turned off, the following alarms are also generated: z SRVO-001 Operator panel E-Stop z SRVO-004 Fence open z SRVO-007 External emergency stop z SRVO-204 External (SVEMG abnormal) E-Stop z SRVO-280 SVOFF input Check the alarm history display on the teach pendant.
