Jenna squinted at the small LCD screen on the drive for the main corrugator feed belt. A910 – UV.
Check the small plastic plug connecting the fan cable to the drive's drive board. Ensure it is firmly seated. yaskawa error code a910
The drive uses one or three current sensors (depending on phase count). Over time, these sensors can drift due to thermal stress, electrical spikes, or simply age. When the sensor outputs a non-zero signal at zero current, the A910 alarm trips.
Wait at least for the internal capacitors to fully discharge. Verify there is no voltage using a multimeter. The cable had worn through, shorting two of
Operating the motor at high speeds with zero dwell (rest) time prevents the motor from shedding heat.
A warped rail or misaligned coupling forces the motor to fight against the machine's own structure. Ensure it is firmly seated
Ensure all bearings, gears, and slides are properly lubricated to reduce friction. 2. Verify Parameter Settings
