Description
V/f CL-V/f OLV CLV AOLV
Sets the gain for the slip compensation function. Usually it is not necessary to change
this setting.
Note:
• When A1-02 = 4 [AOLV], you cannot change the setting while the drive is
running.
• Correctly set these parameters before you change the slip compensation gain:
–E2-01 [Motor Rated Current (FLA)]
–E2-02 [Motor Rated Slip]
–E2-03 [Motor No-Load Current]
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation delay time when speed is unstable or when the slip
compensation response is too slow. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the upper limit for the slip compensation function as a percentage of the motor
rated slip.
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation function during regeneration.
0 : Disabled
1 : Enabled Above 6Hz
2 : Enabled Above Defined Range
V/f CL-V/f OLV CLV AOLV
Sets the automatic reduction of motor magnetic flux when the output voltage is
saturated.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the modulation factor that starts the output voltage limit operation when C3-05 = 1
[Output Voltage Limit Selection = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the modulation factor used with C3-18 [Output Voltage Limit Level] for the output
voltage limit operation when C3-05 = 1 [Output Voltage Limit Selection = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the maximum drop width of the voltage reference when C3-05 = 1 [Output Voltage
Limit Selection = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the gain for the motor 2 slip compensation function. Usually it is not necessary to
change this setting.
Note:
Correctly set these parameters before changing the slip compensation gain:
• E4-01 [Motor 2 Rated Current]
• E4-02 [Motor 2 Rated Slip]
• E4-03 [Motor 2 Rated No-Load Current]
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation delay time for motor 2 when speed is unstable or when the
slip compensation response is too slow. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the upper limit for the slip compensation function as a percentage of the motor 2
rated slip.
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation during regenerative operation function for motor 2.
0 : Disabled
1 : Enabled Above 6Hz
2 : Enabled Above Defined Range
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation function mode.
0 : Normal
1 : Advanced
