YASKAWA CIPR-GA50C series Technical Manual page 191

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].

E5-03: Motor Rated Current (FLA)
No.
Name
(Hex.)
E5-03 Motor Rated Current (FLA)
(032B)
Note:
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 drive automatically sets E5-03 to the value input for T2-06 [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
■
E9-06: Motor Rated Current (FLA)
No.
Name
(Hex.)
E9-06 Motor Rated Current (FLA)
(11E9)
Note:
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 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 T4-07 [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 MA/MB-MC 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.
0 : Disabled
