oPE12
Energy Save ON
Yaskawa · A1000 AC Drive
What does oPE12 mean?
The energy savings feature was enabled while the Output Voltage PID function was also active. This condition typically arises when parameter b8-01 (Energy Save) is set to 'Enable' (1) at the same time parameter P1-08 (Output Voltage PID Select) is set to 'Enabled' (1), and the drive's control method (A1-02) is configured for V/f operation.
Common Causes
- Parameter b8-01 (Energy Save) is set to 'Enable' (1)
- Parameter P1-08 (Output Voltage PID Select) is set to 'Enabled' (1)
- The drive's control method (A1-02) is configured for V/f operation (0) concurrently with the above conditions
