057 [Flux Up Mode]
Auto = 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.

058 [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.
Default:

Units:
0.000 Secs
0.000/5.000 Secs
0.001 Secs
059 [SV Boost Filter]
Sets the amount of filtering used to boost
voltage during Sensorless Vector and FVC Vector
(encoderless) operation.

061 [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,” “SV Economize” or “FVC
Vector.”

“Calculate”
“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] in all valid modes and a non-
rotational motor leakage inductance test for the best possible automatic setting of [Ixo Voltage
Drop] in “FVC Vector” mode. 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]. In “FVC Vector” mode, with
encoder feedback, a test for the best possible automatic setting of [Slip RPM @ FLA] is also run. 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: If using rotate tune for “Sensrls Vect” mode, the motor should be
uncoupled from the load or results may not be valid. With “FVC Vector,” either a coupled or
uncoupled load will produce valid results.
“Calculate” (3) = This setting uses motor nameplate data to automatically set [IR Voltage Drop],
[Ixo Voltage Drop], [Flux Current Ref] and [Slip RPM @ FLA].
062 [IR Voltage Drop]
Value of voltage drop across the resistance of the
motor stator at rated motor current. Used only
when parameter 53 is set to “Sensrls Vect,” “SV
Economize” or “FVC Vector.”

Economize or “FVC Vector.”

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.
