Motor Overload (oL1)
Protection
Sets the motor overload protection with electronic thermal protectors.
0 : Disabled
1 : Variable Torque
Note:
When you connect only one motor to a drive, set
L1-01 = 1 [Variable Torque]
.
External thermal relays are not necessary in these conditions.
1
(0, 1)
L1-02
(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
3
(0 - 3)
L1-04
(0483)
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)
1

L1-05
(0484)
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)
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)
L1-13

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

(0488)
Powerloss V/f Recovery
Ramp Time
Sets the time for the drive output voltage to go back to the correct voltage after it
completes speed searches.
Determined by o2-04
(0.0 - 5.0 s)
L2-05

Undervoltage Detection
Lvl (Uv1)
Sets the voltage at which the drive triggers a
Uv1 [DC Bus Undervoltage]
fault. Usually it
is not necessary to change this setting.
Determined by o2-04 and
E1-01
(208/240 V: 150 - 220 V,
480 V: 300 - 440 V)
