Hello, the lower torque limit means the torque limit when regenerating. You can change the value online, there is a mask for the torque limitation under Open-loop/closed-loop control -> Torque limitation.. F7900 means that you motor blocked / speed controller is working as at its limits. This error occurs for example, if the drive tries to accelerate the motor to reach a certain speed, but the load is too high. The drive accelerates then with a high torque value (till the torque limit is reached), to be able to accelerate the motor to reach the speed setpoint. If the load will be too high, the speed cannot be reached, the speed controller is then working at the torque limit and the error F7900 occurs. You can check your mechanics, maybe open your break or maybe your drive is undersized for the load. If you need further assistance, do not hesistate to open a service request: https://support.industry.siemens.com/my/ww/en/requests/#createRequest |
