When Pr.00-17 = 5, 6, or 7kHz, the maximum setting for Pr.00-34 is 4.0 kHz (±2 kHz). The
carrier frequency fluctuation range is according to the diagram below.
00-37
Over-Modulation Gain
Default: 100
Settings 80–120
When the motor operates in the flux-weakening region or voltage saturation region it can be that
a higher voltage output is required. Increase Pr.00-37 to increase the output RMS voltage.
Increasing the over-modulation gain reduces the output current and enhances the motor
efficiency. However, note that low-frequency harmonics created by the six-step square-wave
modulation may occur if the gain is too large.
How to use Pr.00-37:
Gradually increase Pr.00-37 setting value to check if the output current reduces and the
operation performance improves for an optimal over-modulation gain value.
