The control mode parameter sets the basic control strategy of the drive.

The selections available for the connected drive vary by drive family. See Table 4.49 for a few
of the features associated with each control method.

Table 4.49: Selected Features of the Control Methods

Not all of the Yaskawa drives allow the setting of control mode during
initialization. Some drives only have one control mode. DriveWizard

will

make this property available when it can be changed for initialization.




This refers to the specification that the drive was manufactured under in the

country that it was produced. This should be set according to the nameplate specifications.

This refers to the type of factory initialization that will occur. There are three

types of initializations: 2-wire, 3-wire, and user. A 2-wire and 3-wire initialization will
determine how the drive is run and stopped through the digital input terminals. This is available
on all Yaskawa Drives. User initialization is available only on the G5, E7, F7, G7 and P7 drives.
Refer to the product manual of the respective drive for more details on 2-wire and 3-wire control.
