Acceleration Fault
Yaskawa · F7 Drive
¿Qué significa Er - 09 ?
This fault occurs during rotational Auto-Tuning if the motor fails to accelerate within the specified time (C1-01 + 10 seconds). It suggests insufficient torque, an excessive mechanical load, or incorrect acceleration parameters preventing the motor from reaching its target speed during the tuning sequence. Failure to accelerate properly will prevent accurate motor parameter identification.
Causas comunes
- Excessive mechanical load connected to the motor shaft during rotational Auto-Tuning.
- Motor wiring issues (e.g., loose connections, high resistance) causing insufficient current delivery.
- Drive current limit (C4-01) or acceleration time (C1-01) set too low for the motor and load.
- Motor direction (F6-01) or phase rotation (F6-02) is incorrect, causing conflicting forces.
- Motor stator winding damage leading to insufficient torque production.
Pasos de reparación & Lista de verificación

- 1
1. Ensure the motor is completely decoupled from the mechanical load for rotational Auto-Tuning.
- 2
2. Power down the Drive and inspect all motor cable connections at the Drive (U, V, W) and motor terminals for tightness.
- 3
3. Increase parameter C1-01 (Acceleration Time 1) by 20-50% to allow more time for acceleration during tuning.
- 4
4. Temporarily increase the Drive's current limit parameter (C4-01) by 10-20% above the motor's rated current if safe to do so.

5. Confirm that parameter F6-01 (Motor Rotation Direction) is set correctly for the intended rotation during tuning.
