L: Protection Function - YASKAWA CIMR-VU BA0001 Technical Manual

B.2 Parameter Table
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.

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)
Sets stopping method when the motor temperature analog
input (H3-02/10 = E) exceeds the oH4 fault level.
0: Ramp to Stop
1: Coast to Stop
2: Fast-stop
This parameter adjusts the filter on the motor temperature
analog input (H3-02 or H3-10 = E). Increase to add stability,
decrease to improve response.
Determines whether or not to hold the electrothermal value
when the power supply is interrupted.
0: Disabled
1: Enabled
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
C6-02 = B.
Sets the time constant for reducing the sensitivity level when
detecting leakage current. Set in seconds and used during
acceleration and deceleration operation.
Note: This parameter is available only when C6-02 is
set to B. To display this parameter, first set
C6-02 = B.
L2: Momentary Power Loss
Use L2 parameters to configure drive functions for momentary power loss conditions.
