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
