In the world of high-precision motion control, the is a specific warning signal used primarily in Sigma-5 and Sigma-7 series servo drives.
The most common cause is a load that exceeds the motor's rated torque capacity due to mechanical binding or increased friction in the system.
If the SERVOPACK and servomotor capacities are not properly matched, the drive may struggle to maintain current levels, triggering an early warning. Troubleshooting & Remediation Steps yaskawa error code a910
Several factors can trigger this warning, ranging from mechanical fatigue to improper parameter configuration:
Faulty contact in the motor or encoder cables can cause the drive to "misread" the torque requirements. In the world of high-precision motion control, the
While it may seem urgent, is technically a warning (minor fault) rather than a hard alarm. It serves as a preemptive notification that the system is approaching an overload condition . Ignoring this warning typically leads to a full system shutdown via A.710 (Instantaneous Overload) or A.720 (Continuous Overload) alarms. What Does Error Code A.910 Mean?
The threshold for this warning is controlled by parameter Pn52B (Overload Warning Level). If this is set too low (e.g., 10–20%), the warning may appear prematurely during normal operation. Ignoring this warning typically leads to a full
High-frequency acceleration and deceleration or operating at peak torque for extended periods can build up heat faster than the motor can dissipate it.
