Yaskawa Error Code A910 Link [exclusive]
The A.910 code is present throughout several generations of the Yaskawa SERVOPACK family. While the core engineering issue remains an overload condition, subtle differences exist based on the drive generation:
If the drive's communication timeout (Watchdog) is set too low, minor network jitters can trigger the alarm.
If you can provide the (e.g., SGD7S-xxxx), I can help find the precise manual for your device.
The Yaskawa is a common overload warning primarily associated with Sigma-series servo drives, such as the Sigma-7 and Sigma-3 . Unlike a critical "fault" that stops the motor immediately, this code acts as an alarm or minor fault , signaling that the system is approaching its operational limits.
The alarm threshold parameter Pn52B may be set too low. If the factory default is modified down prematurely, normal operation spike currents trigger the warning. 5. Hardware Degradation within the SERVOPACK yaskawa error code a910 link
Inspect the power and encoder cables for loose contacts or incorrect wiring. Excessive Load
To isolate whether the error is in the or the motor (encoder) : Swap the SERVOPACK with a known working spare.
Yaskawa error code A.910 Overload Warning that appears on Sigma series servo drives
Rapidly reversing directions with heavy, high-inertia loads. 4. Poorly Adjusted Overload Warning Levels ( Pn52B ) The Yaskawa is a common overload warning primarily
: Faulty wiring or electromagnetic interference (EMI) on the encoder feedback line introduces tracking jitter, prompting erratic torque spikes.
If the communication timeout is too aggressive (e.g., 10ms), try increasing it slightly to allow for normal network latency. 5. Reseat the Option Card
This specific code acts as a preemptive safety threshold. It warns operators that the system is rapidly approaching a hard or A.720 (Continuous Overload) hard fault trip.
The overload warning level (parameter Pn52B ) might be set too low or is unsuitable for the current application. If the factory default is modified down prematurely,
Clean or replace clogged cabinet filter fans, verify that the SERVOPACK internal cooling fan is operating correctly, and ensure the surrounding ambient air does not exceed 55°C (131°F). Diagnostic Cross-Reference: SERVOPACK vs. Robot Controllers
High temperatures inside the SERVOPACK panel (above 55°C) can trigger thermal-related warnings.
To minimize production interruptions from recurring overload warnings, implement these field routines:
High acceleration and deceleration rates demand peak current output. If a machine's duty cycle has been shortened or modified to increase production speed, the thermal calculation will rise rapidly. The drive cannot dissipate heat fast enough, triggering the safety warning. 3. Incorrect Parameter Scaling
