Description
V/f CL-V/f OLV CLV AOLV
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 = 1 to 6 [Enabled].
External thermal relays are not necessary in these conditions.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets drive operation when the PTC input signal entered into the drive is at the oH3
[Motor Overheat Alarm] detection level.
0 : Ramp->Stop
1 : Coast->Stop
2 : Fast Stop (C1-09)
3 : Alarm Only
V/f CL-V/f OLV CLV AOLV
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)
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for the PTC input signal entered to the drive. This
parameter prevents accidental motor overheat faults.
V/f CL-V/f OLV CLV AOLV
Sets the reference current for the motor 1 thermal overload detection.
Note:
When the current level > 0.0 A, you cannot set this value < 10% of drive rated
current.
V/f CL-V/f OLV CLV AOLV
Sets the reference current for the motor 2 thermal overload detection.
Note:
When the current level > 0.0 A, you cannot set this value < 10% of drive rated
current.
V/f CL-V/f OLV CLV AOLV
Sets the function that keeps the current electronic thermal protector value when the
drive stops receiving power.
0 : Disabled
1 : Enabled
Description
V/f CL-V/f OLV CLV AOLV
Sets the drive operation after a momentary power loss.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
