[Flux Up Mode]

Automatic = Flux is established for a calculated time period based on
motor nameplate data. [Flux Up Time] is not used.

Manual = Flux is established for [Flux Up Time] before acceleration.

[Flux Up Time]

Sets the amount of time the drive will use to try and achieve full motor
stator flux. When a Start command is issued, DC current at current limit
level is used to build stator flux before accelerating.

[Autotune]

Provides a manual or automatic method for setting [IR Voltage Drop],
[Flux Current Ref], and [Ixo Voltage Drop]. Valid only when parameter 53
is set to “Sensrls Vect” or “SV Economize.”

“Ready” (0) = Parameter returns to this setting following a “Static Tune” or “Rotate Tune.” It also permits manually setting
[IR Voltage Drop], [Ixo Voltage Drop], and [Flux Current Ref].

“Static Tune” (1) = A temporary command that initiates a non-rotational motor stator resistance test for the best possible
automatic setting of [IR Voltage Drop]. A start command is required following initiation of this setting. The parameter
returns to “Ready” (0) following the test, at which time another start transition is required to operate the drive in normal
mode. Used when motor cannot be rotated.

“Rotate Tune” (2) = A temporary command that initiates a “Static Tune” followed by a rotational test for the best possible
automatic setting of [Flux Current Ref]. A start command is required following initiation of this setting. The parameter
returns to “Ready” (0) following the test, at which time another start transition is required to operate the drive in normal
mode. Important: Used when motor is uncoupled from the load. Results may not be valid if a load is coupled to the
motor during this procedure.

“Calculate” (3) = This setting uses motor nameplate data to automatically set [IR Voltage Drop], [Ixo Voltage Drop], [Flux
Current Ref], and [Slip RPM @ FLA].

[IR Voltage Drop]

ATTENTION: Rotation of the motor in an undesired direction can occur during this procedure. To
guard against possible injury and/or equipment damage, it is recommended that the motor be
disconnected from the load before proceeding.
