Official Troubleshooting Steps
Code type: Operator programming error Manual section: Yaskawa V1000 Troubleshooting Attempted to use a function in the V/f motor control method that is only possible in Open Loop Vector Control. Check the motor control method and the functions available. Simple V/f with PG was enabled while not in V/f Control (H6-01 = 3). To use Simple V/f with PG, ensure the motor control method has been set to V/f Control (A1-02 = 0). In Open Loop Vector Control, n2-02 is greater than n2-03 Correct parameter settings so that n2-02 is less than n2-03. In Open Loop Vector Control, C4-02 is greater than C4-06 Correct parameter settings so that C4-02 is less than C4-06. In OLV/PMl, parameters E5-02 to E5-07 are set to 0. - Set the correct motor code in accordance with the motor being used (E5-01). - When using a special-purpose motor, set E5-oo in accordance with the Test Report provided. The following conditions are true in PM Open Loop Vector Control: - E5-03 does not equal 0 - E5-09 and E5-24 are both equal to 0, or neither equals 0 - Set E5-09 or E5-24 to the correct value, and set the other to “0”. - Set the motor-rated current for PM to “0” (E5-03). Note: Use U1-18 to find parameters set outside of the specified setting range. Other errors are given precedence over oPE08 when multiple errors occur simultaneously.
