◆ 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.
■
L1: Motor Protection
■ L2: Momentary Power Loss Ride-Thru
No. (Addr.) Name Description Setting Page
L1-01
(480H)
<10> Default setting is determined by the control mode (A1-02).
Motor Overload Protection
Selection
0: Disabled
1: Standard Fan Cooled
4: PM motor with variable torque
The drive may not be able to provide protection when multiple motors are used, even if
overload is enabled in L1-01. Set L1-01 to 0 and install separate thermal relay to each motor.

Default: 0
Min: 0
Max: 1
213
L1-16
(441H)
Motor 1 Overheat Temperature
Sets the temperature for motor 1 that triggers an overheat fault (oH5).

Default: 120
Min: 50
Max: 200
213
L1-19
(444H)
Operation at Thermistor
Disconnect(THo) (NTC)
Determines what action the drive should take when a thermistor disconnect fault occurs (Tho).
0: Ramp to stop
1: Coast to stop
2: Fast Stop (decelerate to stop using the deceleration time in C1-09)
3: Alarm only ("THo" will flash)
Note: This parameter is available in models CIMR-E4A0930 and 4A1200.
Default: 3
Min: 0
Max: 3
214
L1-20
(445H)
Operation at Motor Overheat
(oH5)
Det
ermines what action th
e drive should take when a motor overheat fault occurs (oH5).
0: Ramp to stop
1: Coast to stop
2: Fast Stop (decelerate to stop using the deceleration time in C1-09)
3: Alarm only ("oH5" will flash)

L2-01
(485H)
Momentary Power Loss Operation
Selection
0: Disabled. Drive trips on (Uv1) fault when power is lost.
1: Recover within L2-02. Uv1 will be detected if power loss is longer than L2-02.
2: Recover as long as CPU has power. Uv1 is not detected.
3: KEB Ride-Thru operation within L2-02.
4: KEB Ride-Thru as long as CPU has power.
5: Ramp to Stop with KEB deceleration.
Default: 0
Min: 0
Max: 5
