Auto-Tuning for Permanent Magnet Motors
Automatically sets the V/f pattern and motor parameters E1-
oo
and E5-
oo
when a PM motor is used. Additionally, the
feature also sets some F1-
oo
parameters for speed feedback detection in Closed Loop Vector.

PM Motor Parameter
Settings
T2-01 = 0
• Motor does not rotate during Auto-Tuning.
• Motor data similar to
report or motor nameplate.
YES
YES
YES
PM Stationary Auto-
Tuning
T2-01 = 1
• A motor test report listing motor data is not available.
• Drive automatically calculates and sets motor parameters.

YES
PM Stationary Auto-
Tuning for Stator
Resistance
T2-01 = 2
• Useful to tune the drive when the motor data were set up
manually or by motor code and the cable is longer than 50
m.
• Should also be performed if the cable length has changed
after prior tuning.
YES
YES
YES
Z Pulse Offset Tuning
T2-01 = 3
• PG encoder has been replaced. Calculates the Z Pulse
offset.
• Requires the motor to rotate with no load or very low load.
–
–
YES
Back EMF Constant
Tuning
T2-01 = 11
• Use when a motor test is not available.
• Tunes the motor induction voltage only.
• Should be performed after motor data are set and the
encoder offset is adjusted.
• The motor must be uncoupled from the mechanical system
(remove loads).
–
–
YES
High Frequency
Injection Parameter
Tuning
T2-01 = 13
• The motor rotated in reverse or STo fault (Motor Step-Out)
occurred at startup in OLV/PM.
• Low speed and insufficient or no torque after activating the
high frequency injection control (n8-57 = 1) in AOLV/
PM.
• Faults, such as the motor rotating in reverse, occurred when
the power was turned on during initial startup in CLV/PM.
–
YES
YES
PM Rotational Auto-
Tuning
T2-01 = 14
• A motor test report listing motor data is not available.
• Motor can be decoupled from the load and rotate freely
while Auto-Tuning is performed. Drive automatically
calculates and sets motor parameters.
• PM Rotational Auto-Tuning gives more accurate results
than Stationary Auto-Tuning.
