E2-01 Motor Rated Current
10% to 200% of the drive
rated current
Determined by
o2-04
Note: 1. The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) if the
drive is set for a maximum applicable motor capacity up to and including 11 kW, 2A0031, 4A0021 (input voltage of 460 V or higher)
or 4A0027 (input voltage of lower than 460 V) and one decimal place (0.1 A) if the maximum applicable motor capacity is higher than
11 kW, 2A0046, 4A0027 (input voltage 460 V or higher) or 4A0034 (input voltage lower than 460 V).
2. 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.

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. Name Setting Range Default
L1-01 Motor Overload Protection Selection 0, 1, 4
Determined by
A1-02
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 5 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 Figure i.55.
