u E2: Motor 1 Parameters
These parameters contain the motor data needed for motor 1. Enter the motor data into these parameters when Auto-Tuning
cannot be performed.
n E2-01: Motor Rated Current
Provides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped on
the motor nameplate. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.
No. Parameter Name Setting Range Default
E2-01 Motor Rated Current
10% to 150% of the drive
rated current <1>
Determined by
o2-04
<1> Display is in the following units based on drive model:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 A units
2o0054 to 2o0248 and 4o0034 to 4o0414: 0.1 A units
Note: An oPE02 error will occur if the motor rated current in E2-01 is set lower than the motor no-load current in E2-03. Set E2-03 correctly to
prevent this error.
n E2-03: Motor No-Load Current
Set the no-load current for the motor in amperes when operating at the rated frequency and the no-load voltage. The drive sets
E2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning 2, 3). The motor no-load current
listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a copy of the
motor test report.
No. Parameter Name Setting Range Default
E2-03 Motor No-Load Current 0.00 A to [E2-01] <1>
Determined by
o2-04
<1> Display is in the following units based on drive model:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 A units
2o0054 to 2o0248 and 4o0034 to 4o0414: 0.1 A units
