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.
