Motor Overload (oL1)
Protection
Sets the motor overload protection with electronic thermal protectors.
0 : Disabled
1 : Variable Torque
4 : PM Variable Torque
Note:
When you connect only one motor to a drive, set L1-01 = 1 or 4 [Variable Torque or
PM Variable Torque] . External thermal relays are not necessary in these conditions.

(0481)
Motor Overload
Protection Time
Sets the operation time for the electronic thermal protector of the drive to prevent damage
to the motor. Usually it is not necessary to change this setting.
1.0 min
(0.1 - 5.0 min)

L1-03
(0482)
Motor Thermistor oH
Alarm Select
Sets drive operation when the PTC input signal entered into the drive is at the oH3 [Motor
Overheat Alarm] detection level.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only

Motor Thermistor oH
Fault Select
Sets the drive operation when the PTC input signal to the drive is at the oH4 [Motor
Overheat Fault (PTC Input)] detection level.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)

Motor Thermistor Filter
Time
Sets the primary delay time constant for the PTC input signal entered to the drive. This
parameter prevents accidental motor overheat faults.
0.20 s
(0.00 - 10.00 s)
353
L1-08
(1103)
oL1 Current Level
Sets the reference current for the motor 1 thermal overload detection. When the current
level > 0.0 A, you cannot set this value < 10% of drive rated current.
0.0 A
(0.0 A or 10% to 150% of
the drive rated current)
353
L1-09
(1104)
oL1 Current Level for
Motor 2
Sets the reference current for the motor 2 thermal overload detection. When the current
level > 0.0 A, you cannot set this value < 10% of drive rated current.
0.0 A
(0.0 A or 10 to150% of
the drive rated current)

Motor Overload Memory
Selection
Sets the function that keeps the current electronic thermal protector value after power loss.
0 : Disabled
1 : Enabled
2 : Enabled, using RTC

RUN
Leakage Current Filter
Time1
Sets the leakage current detection reduction filter time constant during constant speed run.
Note:
You can set this parameter when C6-02 = B [Carrier Frequency Selection = Leakage
Current Detection Reduction Rate PWM] .

L1-23
(0769)
RUN
Leakage Current Filter
Time2
Sets the leakage current detection reduction filter time constant during acceleration/
deceleration.
Note:
• You can set this parameter when C6-02 = B [Carrier Frequency Selection = Leakage
Current Detection Reduction Rate PWM] .
•
When the setting value increases, the current monitor also starts up slowly. Examine
the relevant sequence for problems.
