amps.
Parameter Number 226
Related Parameters 227

Autotune
Stop drive before changing this parameter.
Provides an automatic method for setting Parameter 228 (IR Voltage Drop) and Parameter
229 (Flux Current Ref), which affect sensorless vector performance. Parameter 226 (Motor
NP FLA) must be set to the motor nameplate full load amps before running the Autotune
procedure.
0 = Ready/Idle (Default)
1 = Static Tune
2 = Rotate Tune
Ready (0) – Parameter returns to this setting following a Static Tune or Rotate Tune.
Static Tune (1) – A temporary command that initiates a non-rotational motor stator
resistance test for the best possible automatic setting of Parameter 228 (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 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 Parameter 229 (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.
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.
