Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 39)

Parameter Descriptions 3-13
Provides a manual or automatic method for setting IR Voltage Drop (62), Flux Current
Ref (63) and Ixo Voltage Drop (64). Valid only when Motor Cntl Sel (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 (62), Ixo Voltage Drop (64) and Flux
Current Ref (63).
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 (62) in all
valid modes and a non-rotational motor leakage inductance test for the best possible
automatic setting of Ixo Voltage Drop (64) in FVC Vector Mode. A start command is
required following the 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 the 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 (63). 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: Rotate Tune (2) is used when the 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 (62), Ixo Voltage (64) and Flux Current Ref (63).

ATTENTION: Rotation of the motor in an undesired direction can occur
during this procedure (Autotune (61) = Rotate Tune (2)). To guard against
possible injury and/or equipment damage, it is recommended that the
motor be disconnected from the load before proceeding.
