L: Protection Function
L parameters provide protection to the drive and motor, such as: control during momentary power loss, Stall Prevention,
frequency detection, fault restarts, overtorque detection, torque limits and other types of hardware protection.

Motor Overload Protection
Selection
Sets the motor thermal overload protection (oL1) based on the
cooling capacity of the motor.

Note:
When using multiple motors the drive may not be able
to provide protection, even if overload is enabled in L1-01. Set
L1-01 to 0 and ensure each motor has separate thermal relays
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.

Leakage Current Filter Time
Constant 1
Sets the time constant for reducing the sensitivity level when
detecting leakage current. Set in seconds and used when
operating at constant speed.
Note:
This parameter is available only when C6-02 is
set to B. To display this parameter, first set
