Once rated flux is reached in the motor, normal operation can begin and the
desired acceleration profile achieved.

Flux Up Attributes

ID Access Attribute
558 Set Flux Up Control
559 Set Flux Up Time
(1) This is the time designated for the Manual Delay setting. This attribute is not supported by the Automatic delay method. The
flux-up feature is disabled if FluxUpControl is set to Manual Delay and FluxUpTime is set to 0.
FluxUpControl Attribute
When the motion axis is enabled, DC current is applied to an induction motor
to build stator flux before transitioning to the Running state. This attribute
controls how an induction motor is to be fluxed in the Starting state prior to
transitioning to the Running state.
Table 188 - FluxUp Control Delay Methods
Delay Method Description
No delay The axis transitions immediately to the Running state while the motor flux is building.
The axis remains in the Starting state while the motor stator flux is building according to the
Manual delay
Flux Up Time attribute.
The drive determines the amount of delay time to fully flux the motor based on the motor
Automatic delay
configuration attribute data or measurements.
FluxUpTime Attribute
When FluxUpControl is configured for Manual Delay, this attribute sets the
length of delay time to fully flux the motor before transitioning to the Running
state.
