E5-03: Motor Rated Current (Fla); E9-06: Motor Rated Current (Fla); L1-01: Motor Overload (Ol1) Protection - YASKAWA T103 Installation & Primary Operation

12 UL Standards
Note:
• If E2-01 < E2-03 [Motor No-Load Current], the drive will detect oPE02 [Parameter Range Setting Error].
• The display unit is 0.1 A.
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.
Name
(Hex.)
E5-03 PM Motor Rated Current
(FLA)
(032B)
Note:
The display unit is 0.1 A.
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.
Name
(Hex.)
E9-06 Motor Rated Current (FLA)
(11E9)
Note:
The display unit is 0.1 A.
The setting value of E9-06 is the reference value for motor protection. Enter the motor rated current written on the
motor nameplate. Auto-Tuning the drive will automatically set E9-06 to the value input for "Motor Rated Current".

L1-01: Motor Overload (oL1) Protection

No.
Name
(Hex.)
L1-01 Motor Overload (oL1)
Protection
(0480)
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 frequency
• Motor thermal characteristics
• Time characteristics
If the drive detects motor overload, the drive will trigger an oL1 [Motor Overload] and stop the drive output.
Set H2-01 = 1F [Term M1-M2 Function Selection = Motor Overload Alarm (oL1)] to set a motor overload alarm. If
the motor overload level is more than 90% of the oL1 detection level, the output terminal activates and triggers an
overload alarm.
