P05, A19
Motor 1 / 2 (Online tuning)
Long run under "Dynamic torque control" or "Slip compensation control" causes motor temperature change,
varying the motor parameters. This changes the motor speed compensation amount, resulting in motor speed
deviation from the initial rotating speed.
Enabling online tuning identifies motor parameters covering the motor temperature change to decrease the motor
speed fluctuation.
To perform online tuning enabled with P05/A19, set P04 (Auto-tuning) to "2."
Note: Online tuning can be performed only when F42 = 1 (Dynamic torque control) or when F42 = 2
(V/f control with slip compensation active) and F37 = 2 or 5 (Auto torque boost).

Speed Control 2, Speed Control 1,
Speed Control (Jogging) (Integral time)
These function codes are used to configure the Automatic Speed Regulator (ASR) by selecting the PI controller or
P controller.
Setting the function code data to "999" selects the P controller.
P06 to P08
Motor 1 (No-load current, %R1 and %X)
P06 through P08 specify no-load current, %R1 and %X, respectively. Obtain the appropriate values from the test
report of the motor or by calling the manufacturer of the motor.
Performing auto-tuning automatically sets these parameters.
No-load current (P06)
Enter the value obtained from the motor manufacturer.
%R1 (P07)
Enter the value calculated by the following expression.

%R1
where,
R1: Primary resistance of the motor ()
Cable R1: Resistance of the output cable ()
V: Rated voltage of the motor (V)
I: Rated current of the motor (A)
%X (P08)
Enter the value calculated by the following expression.

XCableXM)(X2/XM×X2X1
%X
where,
X1: Primary leakage reactance of the motor ()
X2: Secondary leakage reactance of the motor (converted to primary) ()
XM: Exciting reactance of the motor ()
Cable X: Reactance of the output cable ()
V: Rated voltage of the motor (V)
I: Rated current of the motor (A)
For reactance, use the value at the base frequency (F04).
