Unlocking Tips to Fix SP9011 SSPA:11 Overvolt Power Circuit Errors
SP9011 SSPA:11 Overvolt Power Circuit An overvoltage of the DC link section of the power supply (PS) has been detected, resulting in a power supply alarm indication of 7. This indicates a power supply selection error, where the maximum output specification of the power supply (PS) has been exceeded.Read more
SP9011 SSPA:11 Overvolt Power Circuit
An overvoltage of the DC link section of the power supply (PS) has been detected, resulting in a power supply alarm indication of 7. This indicates a power supply selection error, where the maximum output specification of the power supply (PS) has been exceeded.
Possible Solutions
Amplifier Indication
The amplifier indication 11 refers to the beta amplifier (drive) of the system. This indicates a specific issue related to the amplifier’s operation.
The alpha power amplifier indication 07 points to another specific issue related to the power amplifier. Both indications may be related to the overvolt power circuit problem.
It is recommended to consult the system manual or contact technical support for further assistance in troubleshooting and resolving the issues with the power circuit and amplifiers.

Excessive Motor Load Torque
In the SP9002 SSPA:02, one of the common issues faced is the inability of the motor speed to follow a specified speed. This is often due to an excessive motor load torque being detected. To resolve this issue, there are a few steps that can be taken:
1. Check and Correct Cutting Conditions
The first step is to check and correct the cutting conditions to decrease the load on the motor. This can be done by adjusting parameters such as feed rate, depth of cut, and cutting speed. By optimizing these parameters, the load on the motor can be reduced, allowing it to better match the specified speed.
2. Correct Parameter No. 4082
Another possible solution is to correct Parameter No. 4082, which controls the acceleration and deceleration time. If the acceleration/deceleration time is insufficient, it can cause the motor speed to deviate from the specified speed. By adjusting this parameter, you can ensure that the motor has enough time to reach and maintain the desired speed.
By following these steps, you can address the issue of the motor speed not being able to follow a specified speed and the detection of excessive motor load torque. It is important to carefully analyze the cutting conditions and adjust the relevant parameters to optimize the motor performance.
