<3> If this parameter is set to 0, the drive will be unable to respond to MEMOBUS/Modbus commands.
<4> Default setting is determined by drive software version.
PRG: 1016 and later: 100 to 32000 Hz
PRG: 1015 and earlier: 1000 to 32000 Hz
<5> When set for sourcing, +5 V/1.5 kΩ or higher, +8 V/3.5 kΩ or higher, +10 V/10 kΩ or higher. When set for sinking, the external power supply
should be +12 Vdc, ±5% with 16 mA or less.
Note: Cycle power to the drive to enable MEMOBUS/Modbus settings.

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.

Description
Sets the level of the value selected in H6-01 when a
frequency with the value set in H6-02 is input.
Sets the level of the value selected in H6-01 when 0 Hz is
input.
Select the pulse train monitor output function (value of the
o-oo part of Uo-oo).
Refer to U: Monitors on page 371
Example: To select U5-01, set "501. "When not using this
parameter or when using in the through mode, set "000".
<5>
Sets the terminal MP output signal frequency when the
monitor value is 100%. Set H6-06 to 102 and H6-07 to 0 to
make the pulse train monitor output equal to the output
frequency.
Description
L1: Motor Protection Functions
Use L1 parameters to configure motor protective functions.
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
3: Vector Motor with a Speed Range of 1:100
4: PM Motor with Variable Torque
6: General Purpose Motor (50 Hz)
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.
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.
Sets operation when the motor temperature analog input
(H3-02/10 = E) exceeds the oH3 alarm level.
0: Ramp to Stop
1: Coast to Stop
2: Fast-stop using C1-09
3: Alarm Only ("oH3" will flash)
