YASKAWA ELECTRIC SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual 343
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.

Pulse Train Monitor
Selection
Select the pulse train monitor output function (value of the
- part of U-).
Refer to U: Operation Status Monitors on page 358 for
the list of U monitors.
Example: To select U5-01, set “501. ”When not using this
parameter or when using in the through mode, set “000”.

Pulse Train Monitor Scaling
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.

<15> Parameter can be changed during run.
<25> If this parameter is set to 0, the drive will be unable to respond to MEMOBUS/Modbus commands.
<26> The availability of certain functions depends on the control method used.
<36> Default setting is determined by the initialize mode the drive is set for (o2-09).

L1: Motor Protection
Use L1 parameters to configure motor protective functions.
L1-01
Motor Overload Protection
Selection
Sets the motor thermal overload protection (oL1) based on
the cooling capacity of the motor.
0: Disabled
1: Standard Fan Cooled (speed range < 10:1)
2: Standard Blower Cooled (speed range ≥ 10:1)
3: Vector Motor (speed range 100:1)
4: PM motor with variable torque
NOTICE: When using a single drive to operate multiple
motors, set L1-01 to 0 and ensure each motor has a thermal
relay installed.

L1-02
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.

Operation Selection (PTC
input)
Sets operation when the motor temperature analog input
(H3-02 and H3-10 = E) exceeds the oH3 alarm level (PTC
input level: Tr-5°C).
0: Ramp to Stop
1: Coast to Stop
2: Fast-stop using C1-09
