Fig. 6-58 PWM mode optimization selection
Unit place: Enable the over-modulation
This function determines whether to enable the over-modulation function controlled by V/F. The
over-modulation function is always enabled in the vector control mode.
0: Disabled
Disable the over-modulation function controlled by V/F.
1: Enabled
Enable the over-modulation function controlled by V/F.
Tens place: Automatic adjustment selection for carrier wave frequency
0: Disabled
1: Enabled
When the carrier wave frequency adjust automatically to select the actions, the drive can adjust the
carrier wave frequency automatically according to its internal temperature. At this moment, the actual
maximum working carrier wave frequency of the drive is limited by the carrier wave frequency (P12.02)
set by the function code.
Hundreds place: Modulation mode
0: Two-phase / three-phase switching
1: Three-phase modulation
Thousands place: Low frequency carrier limit
0: Disable
1: Enable
0: Manual selection
When P12.05 current loop proportional gain is selected and P12.06 current loop integral time takes effect,
the current loop gain can be adjusted by changing P12.05 and P12.06.
