L1: Motor Protection Functions
Use L1 parameters to configure motor protective functions.

Motor Overload
Protection
Selection
Sets the motor thermal overload protection (oL1) based on the
cooling capacity of the motor.
0: Disabled
1: General Purpose Motor (Standard Fan-Cooled)
2: Drive Dedicated Motor with a Speed Range of 1:10
NOTICE: When
multiple motors are used the drive may not be able
to provide protection, even if it is enabled in L1-01. Set L1-01 to “0”
and ensure each motor has a thermal relay installed.

Motor Overload
Protection Time
Sets the motor thermal overload protection (oL1) time.
A larger L1-02 time will increase the time for an oL1 fault to occur.
This parameter does not typically require adjustment. Should be set
in accordance with the overload tolerance of the motor.
