Motor Cool Type for
OL1 Calc
Sets the motor overload protection with electronic thermal protectors.
0 : Disabled
1 : VTorque
2 : CT 10:1 Speed Range
3 : CT 100:1 SpeedRange
4 : PM VTorque
5 : PM CTorque
6 : VT (50Hz)
Note:
When only one motor is connected to a drive, set L1-01 ≠ 0 [Disabled]. External
thermal relays are not necessary in these conditions.

OL1 Protect 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.

Motor oH AL Reaction
Select
Sets drive operation when the PTC input signal entered into the drive is at the oH3
[Motor Overheat Alarm] detection level.

Motor oH FLT Reaction
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->Stop
1 : Coast->Stop
2 : Fast Stop (C1-09)

Motor Therm.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)

L1-09
(1104)
M2 oL1 Curr.Level
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 oL1 Memory
Selection
Sets the function that keeps the current electronic thermal protector value when the
drive stops receiving power.

RUN
LeakCurrFil Tim1
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 Rejection PWM].

L1-23
(0769)
RUN
LeakCurrFil Tim2
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 Rejection PWM].
• When the setting value increases, the current monitor also starts up slowly.
Examine the relevant sequence for problems.
