Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain for the slip compensation function. Usually it is not necessary to change
this setting.
Note:
Correctly set these parameters before changing the slip compensation gain:
• E2-01 [Motor Rated Current (FLA)]
• E2-02 [Motor Rated Slip]
• E2-03 [Motor No-Load Current]
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the upper limit for the slip compensation function as a percentage of the motor
rated slip.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the slip compensation function during regenerative operation.
0 : Disabled
1 : Enabled Above 6Hz
2 : Enabled Above C3-15
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the automatic reduction of motor magnetic flux when the output voltage is
saturated.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the modulation factor that starts the output voltage limit operation when C3-05 = 1
[Output Voltage Limit Selection = Enabled].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the maximum drop width of the voltage reference when C3-05 = 1 [Output Voltage
Limit Selection = Enabled].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the upper limit for the slip compensation function as a percentage of the motor 2
rated slip.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the slip compensation during regenerative operation function for motor 2.
0 : Disabled
1 : Enabled Above 6Hz
2 : Enabled Above C3-15
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for the slip compensation function in the low speed range. Usually it is not
necessary to change this setting.
