E2 Motor Setup
E2-01 Motor Rated Current
Setting Range:
Model Dependent (see appendix B)
Factory Default: Model Dependent
The Motor Rated Current parameter (E2-01) is necessary information for the Drive motor protection function. The motor
overload protection parameter L1-01 is enabled by default. In addition, motor rated current is used by the torque compensation
function to insure optimum torque production. Set E2-01 to the full load amps (FLA) value stamped on the motor’s
nameplate. During Auto-tuning, it is required for the operator to enter the motor rated current in parameter T1-04 on the
Auto-Tuning menu. If the Auto-tuning operation completes successfully, the value entered into T1-04 will be also written into
E2-01.
For applications employing a Drive that is oversized for the motor, E2-01 may be set as low as 10% of the Drive output current
rating. The ampere value in E2-01 however, must always be greater than the “No Load Current” value in parameter E2-03 or
an OPE02 error will be displayed.
