SRVO-009 Pneumatic pressure alarm Cause: The pneumatic pressure alarm indicates the presence of a defect. If the pneumatic pressure alarm is not detected, however, the most likely cause is the PPABN signal of a robot connection cable being at the 0 V level. Remedy: 1. Repair the pneumatic pressure or check the cable. 2. If the pneumatic pressure signal is not in use, it can be disabled in the system config screen. 3. If this alarm cannot be reset, refer to the Controller Maintenance Manual for more information.
