Incorrect parameter value

What does F01681 mean?

An incorrect or invalid parameter value has been detected. The fault value (r0949) provides additional information about the specific parameter affected, which needs to be corrected for proper operation. An incorrect parameter can lead to misconfigured safety functions or drive behavior.

• Manual entry of a parameter value (e.g., p1082 (Max speed)) that exceeds the allowed limits for the drive or motor.
• Loading an incompatible parameter set from a different drive type or firmware version.
• Corruption of non-volatile memory (NVRAM) leading to an invalid default or stored parameter value.
• Automatic calculation or adaptation function (e.g., motor identification) resulting in an out-of-range parameter value.

Click steps to track your progress.

1. 1

   1. Identify the specific parameter in question by reviewing the fault value (r0949) which often displays the parameter number.

2. 2

   2. Access the identified parameter (e.g., p1082) and check its current value against the permissible range specified in the drive's parameter manual.

3. 3

   3. Enter a valid value for the identified parameter, ensuring it is within the minimum/maximum limits and compatible with the application.

4. 4

   4. If the value persists, perform a parameter reset to factory defaults (e.g., p0010 = 30, p0970 = 1) and re-commission essential parameters.

5. 5

   5. Verify that any linked parameters or functions depending on the affected parameter are also correctly configured.
