◆ 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 [Motor Cool Type for OL1 Calc] through L1-04 [Motor oH FLT Reaction
Select] correctly to enable motor overload and overheat protection.
Refer to the control method and set the motor rated current with E2-01 [Mot Rated Current (FLA)], E5-03 [PM
Mot Rated Current (FLA)], or E9-06 [Motor Rated Current].
■ E2-01 Mot Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Mot Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04 and
C6-01
(10% to 200% of the drive
rated current)
Note:
• If E2-01 < E2-03 [Mot Rated Current (FLA) < Mot No-Load Current] the drive will detect oPE02 [Parameter Range Setting Error].
• The default settings and setting ranges are in these units:
–0.01 A: 4002 to 4023
–0.1 A: 4031 to 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 as written on the motor nameplate. The value of E2-01 is automatically set to the
value input for “Motor Rated Current” by the Auto-Tuning process.
■ E5-03 PM Mot Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E5-03
(032B)
PM Mot Rated Current
(FLA)
Sets the PM motor rated current (FLA).
Determined by E5-01
(10% to 200% of the drive
rated current)
Note:
When the drive model changes, the display units for this parameter also change.
• 0.01 A: 4002 to 4023
• 0.1 A: 4031 to 4675
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 StaTun for Stator Resistance
• PM Rotational Auto-Tuning
