C3-05: Output Voltage Limit Selection

No. (Hex.)	Name	Description	Default (Range)
C3-05 (0213)	Output Voltage Limit Selection	Sets the automatic reduction of motor magnetic flux when the output voltage is saturated.	0 (0, 1)

The drive will decrease flux and increase current to compensate torque when voltage is saturated. Make sure that the drive has sufficient output current capacity before you enable this parameter. When this parameter = 1 [Enabled], the output current will increase by 10% at a maximum (at rated load) before it is enabled.

Enable this parameter to increase speed precision when you move heavy loads at high speeds in these conditions:

• Power supply voltage is low

• Motor rated voltage is high

Do not enable this parameter in these conditions:

• Operating a motor in the middle speed range or low speed range

• Power supply voltage is a minimum of 10% more than the motor rated voltage

When you enable this parameter, if the power supply voltage is much less than the motor rated voltage, torque control will not be accurate.
