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 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
Disable motor protection when motor overload protection is not necessary or when the
drive is operating more than one motor.
Refer to Figure 10.5
