◆ Drive Motor Overload and Overheat Protection
The drive motor overload and overheat protection function complies with the National Electric Code (NEC) and
the Canadian Electric Code, Part I (CEC).
Set the Motor Rated Current and L1-01 through L1-04 [Motor Overload Protection 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)], E5-03 [PM
Motor Rated Current (FLA)], or E9-06 [Motor Rated Current (FLA)].
■ E2-01: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04, C6-
01
(10% to 200% of the drive
rated current)
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 2004 - 2042, 4002 - 4023
–0.1 A: models 2056 - 2415, 4031 - 4675
The value set for E2-01 becomes the reference value for motor protection, the torque limit, and torque control.
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: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E5-03
(032B)
Motor Rated Current (FLA)
Sets the PM motor rated current (FLA).
Determined by E5-01
(10% to 200% of the drive
rated current)
Note:
The display units are different for different models:
• 0.01 A: models 2004 - 2042, 4002 - 4023
• 0.1 A: models 2056 - 2415, 4031 - 4675
The drive automatically sets E5-03 to the value input for “PM Motor Rated Current” after you do these types of
Auto-Tuning:
• Manual Entry w/ Motor Data Sheet
• PM Stationary Auto-Tuning
• Stationary (R Only)
• Rotational (Ld, Lq, R, back-EMF)
■ E9-06: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E9-06
(11E9)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by E9-01 and
o2-04
(10% to 200% of the drive
rated current)
Note:
The display units are different for different models:
• 0.01 A: models 2004 - 2042, 4002 - 4023
• 0.1 A: models 2056 - 2415, 4031 - 4675
