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, and other types of hardware protection.
No. Name
Sets the motor thermal overload protection (oL1) based on the
cooling capacity of the motor.
0: Disabled
Motor Overload
1: General Purpose Motor (Standard Fan-Cooled)
L1-01 Protection
2: Drive Dedicated Motor with a Speed Range of 1:10
Selection
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.
Sets the motor thermal overload protection (oL1) time.
Motor Overload A larger L1-02 time will increase the time for an oL1 fault to occur.
L1-02
Protection Time This parameter does not typically require adjustment. Should be set
in accordance with the overload tolerance of the motor.
Determines whether or not to hold the electrothermal value when the
Continuous
power supply is interrupted.
L1-13 Electrothermal
0: Disabled
Operation Selection
1: Enabled
Enables and disables the momentary power loss function.
0: Disabled - Drive trips on (Uv1) fault when power is lost.
Momentary Power
1: Power Loss Ride-Thru Time - Drive will restart if power returns
L2-01 Loss Operation
within the Power Loss Ride-Thru Time.
Selection
2: CPU Power Active - Drive will restart if power returns as long as
the CPU is working.

Description
Selects the stopping method when a communication time-out fault
(CE) is detected.
0: Ramp to stop
1: Coast to stop
2: Fast-stop
3: Alarm only
Enables or disables the communications timeout fault (CE).
0: Disabled - A communication loss will not cause a communication
fault.
1: Enabled - If communication is lost for more than 2 seconds, a CE
fault will occur.
Set the wait time between receiving and sending data.
Selects "request to send" (RTS) control:
0: Disabled - RTS is always on.
1: Enabled - RTS turns on only when sending.
0: FWD/STOP, REV/STOP Method
1: RUN/STOP, FWD/REV Method
0: 0.1 Hz/1
1: o1-03 based
2: 100%/30000
3: 0.1%/1
Description
L1: Motor Protection Functions
Use L1 parameters to configure motor protective functions.
L2: Momentary Power Loss
Use L2 parameters to configure drive functions for momentary power loss conditions.
L3: Stall Prevention Function
Use L3 parameters to configure the Stall Prevention function.
