IGBT Switching Frequency.
Selects the type of PWM modulation.
Higher switching frequencies reduce the audible ‘ringing’ noise from the motor and improve the output current waveform at the expense of increased drive losses.
This parameter defines the minimum effective switching frequency which the drive will use when the drive auto- switches down the switching frequency (Based on Heatsink Temperature and motor current) in order to reduce the losses and heat from the power stage.
When P11-07 is 0, removing the power supply from the drive and re-applying will reset the value of the accumulator.
When P11-07 is 1, the value is retained during power off.
Setting | Function |
|---|---|
0 | Disabled (No retention) |
1 | Enabled (retention). An internal overload accumulator (P0-31) monitors the motor output current over time, and will trip the drive if the usage exceeds the thermal limit. |
Reserved
Select the motor phase orientation.
Setting | Orientation |
|---|---|
0 | U, V, W |

Setting | Modulation type |
|---|---|
0 | 3-Phase |
1 | 2-Phase |
2 | Auto |
