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 “Flux
Vector.”

“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 “Flux 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
“Flux 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: 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].
Speed Feedback
412 [Motor Fdbk Type]
Selects the encoder type; single channel
or quadrature. Options 1 & 3 detect a
loss of encoder signal (when using
differential inputs).

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.
