Note: If the settings for the constants of an Inverter with a different version of software are copied, an OPE error can occur. Contact your Yaskawa representa-
tive if wanting to copy the settings with a different software version.
V/f Data Setting Error
Constants E1-04, E1-06, E1-07, and E1-09 do not satisfy the following conditions:
• E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN)
• E3-02 (FMAX) ≥ E3-04 (FA) > E3-05 (FB) ≥ E3-07 (FMIN)
Constant Setting Error
One of the following constant setting errors exists.
• C6-05 (Carrier Frequency Gain) > 6, the Carrier Frequency Lower Limit (C6-04)
> the Carrier Frequency Gain(C6-05)
• Upper/lower limit error in C6-03 to 05.
• C6-01 is 0 and C6-02 is 2 to E.
• C6-01 is 1 and C6-02 is 7 to E.
EEPROM Write Error
A verification error occurred when writing EEPROM.
• Try turning the power supply off and on again.
• Try setting the constants again.
