Delta used to determine when to switch into Energy Save Bypass. This allows for lower frequency output values to also trigger
Energy Save Bypass functionality. A transfer to bypass occurs after the drive reaches the programmed output frequency (E1-04
to S4-02) for the time specified in the BP Energy Save Bypass Timer (S4-03). Additionally, if frequency input is set below
E1-04 to S4-02, the drive exits Energy Save Bypass. Setting S4-02 to 0 disables Energy Save Bypass functionality.
