Set the Motor Rated Current and L1-01 [Motor Overload (oL1) Protection] to L1-04 [Motor Thermistor oH Fault
Select] correctly to enable motor overload and overheat protection.
Refer to the control method and set the motor rated current with E2-01 [Motor Rated Current (FLA)] or E5-03
[PM Motor Rated Current (FLA)].
E2-01: Motor Rated Current (FLA)
No.
Name
(Hex.)
E2-01 Motor Rated Current (FLA)
(030E)
Note:
• If E2-01 < E2-03 [Motor No-Load Current], the drive will detect oPE02 [Parameter Range Setting Error].
• When the drive model changes, the display units for this parameter also change.
–0.01 A: models 2022 - 2041, 4012 - 4023
–0.1 A: models 2059 - 2519, 4030 - 4380
The value set for E2-01 becomes the reference value for motor protection and the torque limit. Enter the motor
rated current written on the motor nameplate. Auto-Tuning the drive will automatically set E2-01 to the value
input for "Motor Rated Current".
E5-03: PM Motor Rated Current (FLA)
No.
Name
(Hex.)
E5-03 PM Motor Rated Current
(FLA)
(032B)
Note:
The display units are different for different models:
• 0.01 A: models 2022 - 2041, 4012 - 4023
• 0.1 A: models 2059 - 2519, 4030 - 4380
The drive automatically sets E5-03 to the value input for "PM Motor Rated Current" after you do these types of
Auto-Tuning:
• PM Motor Parameter Settings
• PM Stationary Auto-Tuning
• PM Rotational Auto-Tuning
L1-01: Motor Overload (oL1) Protection
No.
Name
(Hex.)
L1-01 Motor Overload (oL1)
Protection
(0480)
Note:
• The default setting and setting range change when the A1-02 [Control Method Selection] setting changes:
–When A1-02 = 0, 2, 3 [V/f, OLV, CLV], the default setting is 1, and the setting range is 0 to 3, 6.
–When A1-02 = 7 [CLV/PM], the default setting is 5, and the setting range is 0, 5.
• When only one motor is connected to a drive, set L1-01 = 1 to 6 [Enabled]. External thermal relays are not necessary in these
conditions.
This parameter enables and disables the motor overload protection with electronic thermal protectors.
The cooling capability of the motor changes when the speed control range of the motor changes. Use an electronic
thermal protector that aligns with the permitted load characteristics of the motor to select motor protection.
The electronic thermal protector of the drive uses these items to calculate motor overload tolerance and supply
overload protection for the motor:
• Output current
• Output speed
• Motor thermal characteristics
• Time characteristics
If the drive detects motor overload, the drive will trigger an oL1 [Motor Overload] and stop the drive output.
