i.5 Start-Up Programming and Operation
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.
E2-01
<1> Display is in the following units:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 A units
2o0054 to 2o0248 and 4o0034 to 4o0414: 0.1 A units
Note: Setting E2-01 ≤ E2-03 will trigger an oPE02 error. Set E2-03 correctly to prevent this error.

H2-03 Terminal MD-ME-MF Function Selection (relay)
n L1-01: Motor Overload Protection Selection
The drive has an electronic overload protection function that estimates the motor overload level based on output current, output
frequency, thermal motor characteristics, and time. When the drive detects a motor overload an oL1 fault is triggered and the
drive output shuts off.
L1-01 sets the overload protection function characteristics according to the motor being used.
No.
L1-01
Note: 1. When the motor protection function is enabled (L1-01≠ 0), an oL1 alarm can be output through one of the multi-function outputs by
setting H2-01 to 1F. The output closes when the motor overload level reaches 90% of the oL1 detection level.
2. Set L1-01 to a value between 1 and 6 when running a single motor from the drive to select a method to protect the motor from overheat.
An external thermal relay is not necessary.
Setting 0: Disabled (Motor Overload Protection Is Not Provided)
Use this setting if no motor overheat protection is desired or if multiple motors are connected to a single drive. If multiple
motors are connected to a single drive, install a thermal relay for each motor as shown in
