2nd Motor Free Setting V/f Frequency 7 Exceeds Lower Limit

What does 292 mean?

For the second motor settings, this warning indicates that the seventh point of the free setting V/f curve (b112) is set higher than the 2nd frequency lower limit (A262). This creates an inconsistent lower boundary for the V/f characteristic for the second motor, potentially restricting the minimum V/f output.

• Parameter b112 (Free setting V/f curve frequency point 7) for the second motor is set to a value higher than parameter A262 (2nd frequency lower limit).
• The V/f curve's maximum frequency point (b112) is configured to exceed the allowed operational lower frequency for the second motor (A262).
• An illogical setting where the highest point of the V/f curve (b112) is above the lowest allowed operational frequency (A262), creating a conflict.

Click steps to track your progress.

1. 1

   Read the current values of parameter b112 (Free setting V/f curve frequency point 7) and parameter A262 (2nd frequency lower limit).

2. 2

   Adjust parameter b112 to be less than or equal to parameter A262, ensuring the V/f curve point respects the lower frequency limit.

3. 3

   Alternatively, if a higher operational lower limit is required, increase A262 to a value greater than or equal to b112.

4. 4

   Store parameter changes to the drive's memory and reboot the drive.
