Rockwell Automation Liqui-Flo V2.0 AC Drive - Manual (Page 85)

Rockwell Automation Publication D2-3518-3 - May 2013 85
Chapter 9
Provides a manual or automatic method for setting IR Voltage Drop (62) and
Flux Current Ref (63), which affect sensorless vector performance. Valid only
when Torque Perf Mode (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 (62) 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. 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
uncoupled from the load.
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.
Calculate (3) = This setting uses motor nameplate data to automatically set IR
Voltage Drop and Flux Current Ref.

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.
IMPORTANT Rotate Tune (2) is used when motor is uncoupled from the load. Results may
not be valid if a load is coupled to the motor during this procedure.
