5.5 E: Motor Parameters
No.
E2-01
Note: 1. Display is in the following units: BA0001 to BA0018, 2A0001 to 2A0040, and 4A0001 to 4A0023: 0.01 A units.
2A0056 to 2A0069, 4A0031 to 4A0038: 0.1 A units.
2. Change E2-01 only after changing the value set to E2-03. Setting E2-01 < E2-03 will trigger an oPE02 error.
n E2-02: Motor Rated Slip
Sets the motor rated slip in Hz. This value is automatically set during Rotational Auto-Tuning.
No.
E2-02
If Auto-Tuning can not be performed calculate the motor rated slip using the information written on the motor nameplate
and the formula below:
E2-02 = f - (n x p)/120
(f: rated frequency (Hz), n: rated motor speed (r/min), p: number of motor poles)
n
E2-03: Motor No-Load Current
Set E2-03 to the motor no-load current at rated voltage and rated frequency. If Rotational Auto-Tuning completes
successfully, this value is automatically calculated. If Auto-Tuning can not be performed, contact the motor manufacturer
for information about the no-load current.
No.
E2-03
Note: Display is in the following units: BA0001 to BA0018, 2A0001 to 2A0040, and 4A0001 to 4A0023: 0.01 A units.
2A0056 to 2A0069, 4A0031 to 4A0038: 0.1 A units.
n
E2-04: Number of Motor Poles
Set the number of motor poles to E2-04. This value must be entered during Auto-Tuning, and will automatically be saved
to E2-04 if Auto-Tuning completes successfully.
No.
E2-04
n E2-05: Motor Line-to-Line Resistance
Sets the line-to-line resistance of the motor stator winding. If the Auto-Tuning completes successfully, this value is
automatically calculated. Remember this value must be entered as line-line and not line-neutral.
No.
E2-05
Note: The setting range becomes 0.00 to 130.00 when using VoBA0002, Vo2A0002, Vo4A0001 and smaller.
If Auto-Tuning is not possible, then contact the motor manufacturer to find out the line-to-line resistance or measure it
manually. When using the manufacturer Motor Test Report, calculate E2-05 by the formulas below.
• E-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the Test Report at 75 °C
• B-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the Test Report at 75 °C.
• F-type insulation: Multiply 0.87 times the resistance value (Ω) listed on the Test Report at 115 °C.
n E2-06: Motor Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of motor rated voltage.
No.
E2-06
n E2-07: Motor Iron-Core Saturation Coefficient 1
This parameter sets the motor iron saturation coefficient at 50% of the magnetic flux. If Rotational Auto-Tuning completes
successfully, then this value is automatically calculated.
