E2: Motor 1 Parameters
u
These parameters contain the most important motor data needed for optimal motor control. The parameters are set automatically
during Auto-Tuning. Set the parameters manually when Auto-Tuning cannot be performed.
E2-01: Motor Rated Current
n
Set E2-01 to the full load amps (FLA) stamped on the motor nameplate. During Auto-Tuning the value must be entered to
parameter T1-04. If Auto-Tuning completes successfully, the value entered will automatically be saved to E2-01.
No.
E2-01
Note: 1. Display is in the following units:
BV0006 to BV0018, 2V0006 to 2V0040, and 4V0002 to 4V0023: 0.01 A units.
2V0056 to 2V0069 and 4V0031 to 4V0038: 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.
E2-02: Motor Rated Slip
n
Sets the motor rated slip in Hz. This value is automatically set during Rotational Auto-Tuning.
No.
E2-02
If Auto-Tuning cannot 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)
E2-03: Motor No-Load Current
n
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 cannot be performed, contact the motor manufacturer for information
about the no-load current.
No.
E2-03
Note: Display is in the following units: BV0006 to BV0018, 2V0006 to 2V0040, and 4V0002 to 4V0023: 0.01 A units. 2V0056 to 2V0069 and
4V0031 to 4V0038: 0.1 A units.
E2-04: Number of Motor Poles
n
Set the number of motor poles to E2-04. If Auto-Tuning completes successfully, the value entered to T1-06 will automatically
be saved to E2-04.
No.
E2-04
E2-05: Motor Line-to-Line Resistance
n
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 BV0002, 2V0002, 4V0001 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
