215

2nd Multi-step Speed Reference 0 Exceeds 2nd Frequency Upper Limit

Omron · MX2 Inverter

What does 215 mean?

For the second motor settings, this warning occurs if the Multi-step speed reference 0 (A220) or output frequency setting (F001) is set higher than the 2nd frequency upper limit (A261). This creates a conflict in the speed constraints for the alternative motor profile, as a programmed speed is above the allowed maximum.

Common Causes

  • Parameter A220 (2nd Multi-step speed reference 0) is set to a value higher than the 2nd frequency upper limit (A261).
  • The commanded output frequency (F001) is attempting to operate above the configured operational upper limit (A261) for the second motor.
  • An external control signal is requesting a speed reference that exceeds the A261 limit, causing a warning.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Read the current values of parameter A220 (2nd Multi-step speed reference 0), F001 (Output frequency setting), and A261 (2nd frequency upper limit).

  2. 2

    Adjust parameter A220 to be less than or equal to parameter A261, ensuring multi-step speed does not exceed the operational upper limit.

  3. 3

    Verify that the output frequency command (F001) remains within the A261 limit during operation, adjusting the command source if needed.

  4. 4

    Save parameter changes to the drive's memory and perform an inverter reset.
