E4-02 = f - (n × p) / 120
• f: Motor rated frequency (Hz)
• n: Rated motor speed (min
• p: Number of motor poles
■
E4-03: Motor 2 Rated No-Load Current
No.
Name
(Hex.)
E4-03 Motor 2 Rated No-Load
Current
(0323)
Note:
When the drive model changes, the display units for this parameter also change.
• 0.01 A: 2004 to 2042, 4002 to 4023
• 0.1 A: 2056 to 2415, 4031 to 4720
You can also manually enter the motor no-load current shown on the motor test report to E4-03. Contact the motor
manufacturer to receive a copy of the motor test report.
Note:
The default setting of the no-load current is for a 4-pole motor recommended by Yaskawa.
■
E4-04: Motor 2 Motor Poles
No.
Name
(Hex.)
E4-04 Motor 2 Motor Poles
(0324)
Auto-Tuning automatically sets E4-04 to the value input for [Number of Motor Poles].
■
E4-05: Motor 2 Line-to-Line Resistance
No.
Name
(Hex.)
E4-05 Motor 2 Line-to-Line
Resistance
(0325)
Note:
This value is the line-to-line resistance for motor 2. Do not use the single-phase resistance to set this parameter.
The drive automatically calculates this value when Auto-Tuning completes successfully. If you cannot do Auto-
Tuning, get the test report from the motor manufacturer. To calculate the motor line-to-line resistance, use the
information shown on the motor nameplate with one of these formulas:
• E-type insulation: the resistance value (Ω) shown on the test report at 75 °C × 0.92
• B-type insulation: the resistance value (Ω) shown on the test report at 75 °C × 0.92
• F-type insulation: the resistance value (Ω) shown on the test report at 115 °C × 0.87
■
E4-06: Motor 2 Leakage Inductance
No.
Name
(Hex.)
E4-06 Motor 2 Leakage Inductance
(0326)
The drive sets this parameter during Rotational Auto-Tuning and Stationary Auto-Tuning.
Note:
You cannot usually find the quantity of voltage drop on the motor nameplate. If you do not know the value of the motor 2 leakage
inductance, get the test report from the motor manufacturer.
