—a pre-alert that the servo drive is operating under excessive load conditions that will soon trigger a more serious overload alarm (typically A.710 or A.720 ) if not corrected.
) times are set too fast, causing the motor to draw excess current to meet the command.
If the machine cycle requires starting torques that continually push the boundaries of the motor's peak torque curve, heat builds up rapidly. This often occurs after an unauthorized modification to production line speeds or acceleration rates. yaskawa error code a910 exclusive
Check if panel fans are working or if the heat sink is obstructed.
Ensure your control cabinets have clean, functioning air filters and climate control units. —a pre-alert that the servo drive is operating
High-cycle rates, overly aggressive acceleration/deceleration curves, or continuous peak-torque demands that exceed the motor's rated capacity. Incorrect Parameter Thresholds: The overload warning level parameter (
If the error persists under normal operation, you may need a motor with higher torque capacity. This often occurs after an unauthorized modification to
Tighten terminal connections or replace damaged, high-flex cables. Pn52B Parameter
The A.910 code acts as an intelligent buffer. The internal microprocessor continuously calculates the dynamic current profile against time ( I2tcap I squared t
