Siemens Drive Fault Code 7902 'link' | 2025-2027 |

| Step | Action | |------|--------| | 1 | Check (actual speed) — does it really exceed p2162? | | 2 | Verify p1082 (maximum speed) ≥ p2162 (overspeed threshold). | | 3 | Increase p2162 slightly (e.g., 1.1× p1082) if mechanical limits allow. | | 4 | Check encoder: cable shielding, terminal tightness, p0400 encoder type. | | 5 | Perform motor data identification (p1910 = 1) and speed controller optimization (p1960 = 1). | | 6 | Increase deceleration time p1121 to avoid regen overshoot. |

Faulty speed feedback from an encoder or incorrectly connected motor cables (e.g., swapping U and W phases) can cause the drive to "think" the motor is stalling. Brake Malfunction: siemens drive fault code 7902

Understanding why the drive triggers a stall fault is the first step in troubleshooting. Common triggers include: SINAMICS G120XA fault F07902 - ID: 109773411 - Support | Step | Action | |------|--------| | 1
