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.

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: 2001 to 2042, B001 to B018, 4001 to 4023
–0.1 A: 2056 to 2082, 4031 to 4060
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 T1-04 [Motor Rated Current].
