YASKAWA U1000 - T1-01: Auto-Tuning Mode Selection

Table i.38 Types of Auto-Tuning for Induction Motors
Type Setting Application Conditions and Benefits
Control Mode
V/f V/f w/PG OLV CLV
Rotational Auto-Tuning T1-01 = 0
• Motor can be decoupled from the load and rotate freely
while Auto-Tuning is performed.
• Motor and load cannot be decoupled but the motor load is
below 30%.
•
Rotational Auto-Tuning gives the most accurate results,
and is recommended if possible.
– – YES YES
Stationary
Auto-Tuning 2
T1-01 = 4
• Motor and load cannot be decoupled and the load is higher
than 30%.
•
A motor test report is available. After entering the no-load
current and the rated slip, the drive calculates and sets all
other motor-related parameters.
– – YES YES
Stationary Auto-Tuning
for Line-to-Line
Resistance
T1-01 = 2
• The drive is used in V/f Control and other Auto-Tuning
selections are not possible.
• Drive and motor capacities differ.
•
Tunes the drive after the cable between the drive and motor
has been replaced with a cable over 50 m long. Assumes
Auto-Tuning has already been performed.
• Should not be used for any vector control modes unless the
motor cable has changed.
YES YES YES YES
Rotational Auto-Tuning
for V/f Control
T1-01 = 3
• Recommended for applications using Speed Estimation
Speed Search or using the Energy Saving function in
V/f Control.
• Assumes motor
can rotate while Auto-Tuning is executed.
Increases accuracy for certain functions like torque
compensation, slip compensation, Energy Saving, and
Speed Search.
YES YES – –
Stationary
Auto-Tuning 3
T1-01 = 5
• A motor test report listing motor data is not available.
• Motor can be driven with a normal duty mode after Auto-
Tuning. A trial run is performed after Auto-Tuning to
automatically
calculate motor parameters needed for vector
control.
– – YES YES

No-Load Operation Test Run
This section explains how to operate the drive with the motor decoupled from the load during a test run.
n
Before Starting the Motor
Check the following items before operation:
•
Ensure the area around the motor is safe.
• Ensure external emergency stop circuitry is working properly and other safety precautions have been taken.
