2nd Motor Starting Frequency Exceeds Upper Limit

What does 231 mean?

For the second motor settings, this warning occurs when the inverter's starting frequency (b082) is set higher than the 2nd frequency upper limit (A261). This inconsistent configuration may prevent the second motor from starting or operating as intended within its defined frequency limits.

• Parameter b082 (Inverter starting frequency) for the second motor is set to a value greater than its 2nd frequency upper limit (A261).
• The drive is configured to start at a frequency (b082) that is logically above its defined operational upper frequency boundary (A261).
• An incorrect value was entered for b082 during system setup, causing it to conflict with A261.

Click steps to track your progress.

1. 1

   Read the current values of parameter b082 (Inverter starting frequency) and parameter A261 (2nd frequency upper limit).

2. 2

   Adjust parameter b082 to be less than or equal to parameter A261, ensuring the starting frequency is within the operational upper limit.

3. 3

   Alternatively, if a higher operational upper limit is desired, increase A261 to a value greater than or equal to b082, considering motor limitations.

4. 4

   Save all parameter changes to the drive's memory and restart the inverter.
