T3: Asr And Inertia Tuning; T4: Ez Tuning - YASKAWA CIPR-GA50C series Technical Manual

0 : mV/(rev/min)
1 : mV/(rad/s)
Note:
• When T2-13 = 0, the drive will use E5-24 [PM Back-EMF L-L Vrms (mV/rpm)] and will automatically set E5-09 [PM Back-EMF
Vpeak (mV/(rad/s))] = 0.0.
• When T2-13 = 1, the drive will use E5-09 and will automatically set E5-24 = 0.0.

T4: EZ Tuning

Use T4 parameters to input the data necessary for motor parameter Auto-Tuning when A1-02 = 8 [Control
Method Selection = EZ Vector Control]. These two modes are available:
T4-01 Setting
0 Follow the instructions in the setup wizard on the keypad to
manually enter the necessary motor parameters.
1 Do only line-to-line resistance tuning.
*1 When you use a PM motor or a synchronous reluctance motor, it is not necessary to enter the rated frequency. The drive will use the
rated rotation speed and number of motor poles to automatically calculate the rated frequency.

V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the motor induced voltage constant (Ke).
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the level of the pull-in current as a percentage of E5-03 [PM Motor Rated Current (FLA)].
Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the type of Control Auto-Tuning.
