How to fix main circuit undervoltage on Inovance IS810N-INT?
If you're experiencing a main circuit undervoltage error with your Inovance Servo Drives, it means the DC bus voltage is lower than the overvoltage threshold. To fix this, improve the power capacity of your system.
What causes Inovance Servo Drives overload and how to resolve it?
Servo drive overload in Inovance systems happens when heat accumulation within the drive reaches a critical level. You can resolve this by using a servo drive of larger capacity and a matching servo motor, reducing the load, and increasing the acceleration/deceleration time.
What to do for motor overload on Inovance IS810N-INT Servo Drives?
If your Inovance Servo Drives report a motor overload, it means the motor's heat accumulation has reached a critical level. To address this, consider using a servo drive with a larger capacity and a matching servo motor. Additionally, reduce the load and increase the acceleration/deceleration time.
What to do if incorrect homing object dictionary appears on Inovance IS810N-INT Servo Drives?
Homing mode (6098h) sets an unsupported value. Set parameters according to the specifications.
What to do if synchronization cycle error is too large appears on Inovance IS810N-INT?
The synchronization cycle error exceeds the threshold. Increase the factory parameter (200E-21h).
What causes angle auto-tuning failure on Inovance Servo Drives?
Angle auto-tuning failure on Inovance Servo Drives is caused by abnormal jitter reported by the encoder during angle auto-tuning. Check the encoder hardware wiring.
How to troubleshoot FPGA sampling operation timeout on Inovance IS810N-INT?
To troubleshoot an FPGA sampling operation timeout on Inovance Servo Drives, find the cause based on the internal fault code (200B-2Eh). Use the recommended encoder cable. If a non-standard cable is used, check that it complies with the specifications and is a shielded twisted pair cable.
How to resolve abnormal position reference increment on Inovance Servo Drives?
An abnormal position reference increment error in Inovance Servo Drives, specifically in CSP mode, indicates that the target position increment is too large. To correct this, decrease the position reference speed, or set a certain acceleration/deceleration curve when the host controller plans the target position.
What causes output to-ground short-circuit on Inovance IS810N-INT Servo Drives?
An output to-ground short-circuit error on Inovance Servo Drives indicates that the servo drive has detected an abnormal motor phase current or bus voltage during self-check at power-on. To resolve this, re-connect the cables or replace them.
