SVE
Zero Servo Fault
Yaskawa · F7 Drive
What does SVE mean?
The motor position moved more than 10,000 revolutions during zero servo operation, indicating a loss of position control. This can be caused by an excessively small torque limit, an overly large load torque, or a fault within the control circuit, possibly due to electrical noise interfering with position feedback.
Additional Steps
Steps 1–2 are listed in Priority Fix.

Inspect and mitigate any sources of signal noise affecting the control circuit and feedback wiring; check shield grounding.
