<2> Motor no-load current is required. If the no-load current is not shown on the motor nameplate, use the default value. The default value is set for
Yaskawa standard motors.
n 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.

Table 4.30 Types of Auto-Tuning for Permanent Magnet Motors
Application Conditions and Benefits
• Motor does not rotate during Auto-Tuning.
• Motor data similar to
report or motor nameplate.
• A motor test report listing motor data is not available.
• Drive automatically calculates and sets motor parameters.
• 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.
• PG encoder has been replaced. Calculates the Z Pulse
offset.
• Requires the motor to rotate with no load or very low load.
• 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).
• Perform High Frequency Injection Parameter Tuning after
setting motor parameters.
Permanent Magnet Motors on page 165
• 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.
Note: High Frequency Injection cannot be used with
an SPM motor.
