Yaskawa Error Code A910

For drives powered by separate control terminals (e.g., S1, S2 for 24VDC), an unstable control supply can sometimes miscommunicate with the main board, indirectly causing a main circuit undervoltage detection logic fault.

: Increased friction in the machine’s mechanical parts (bearings, slides, or gears) is forcing the motor to work harder. yaskawa error code a910

Look for jams, binding, or lack of lubrication. For drives powered by separate control terminals (e

This parameter often controls the position error pulse overflow; if set too tight, it can mimic overload behavior. This parameter often controls the position error pulse

No. If the drive allows you to clear the fault and run, you risk catastrophic motor or drive damage. The current sensors are critical for vector control and overcurrent protection. Ignoring A910 can lead to IGBT failure and a much more expensive repair.

Yes, but rarely. A corrupted parameter o2-04 or o2-05 (current offset settings) can cause the fault. Initialization (Step 2) will resolve this.
