On-Delay Compensation
High speed motors typically operate at low V/f ratios compared to standard 60/120 Hz
motors, and On-Delay Compensation settings may adversely affect the motor voltage and
cause hunting and oscillation. Therefore, On-Delay Compensation Gain is modified to
reduce its effectiveness above 120 Hz as shown in Figure 3 .
Note: When S1-01 = 0, On-Delay Compensation is disabled at all frequencies.
