061 [Autotune]
Provides a manual or automatic method
for setting [IR Voltage Drop] and [Flux
Current Ref], which affect sensorless
vector performance. Valid only when
parameter 53 is set to “Sensrls Vect,” “SV
Economize” or “FVC Vector”

“Ready” (0) = Parameter returns to this setting following a “Static Tune” or “Rotate
Tune.” It also permits manually setting [IR 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] and [Flux Current Ref].
062 [IR Voltage Drop]
Value of voltage drop across the
resistance of the motor stator at rated
motor current. Used only parameter 53 is
set to “Sensrls Vect”, “SV Economize” or
“FVC Vector.”

063 [Flux Current Ref]
Value of amps for full motor flux. Used
only when parameter 53 is set to “Sensrls
Vect”, “SV Economize” or “FVC Vector.”

064 [IXo Voltage Drop]
Value of voltage drop across the leakage
inductance of the motor at rated motor
current. Used only when parameter 53 is
set to “FVC Vector.”

Units:

066 [Autotune Torque]
Specifies motor torque applied to the
motor during the flux current and inertia
tests performed during an autotune.

Units:

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.
