V/f CL-V/f OLV CLV AOLV
Sets the type of motor data that Online Tuning uses for OLV control.
0 : Disabled
1 : Line-to-Line Resistance Tuning
2 : Voltage Correction Tuning
V/f CL-V/f OLV CLV AOLV
Sets the compensation gain when n6-01 = 2 [Online Tuning Selection = Voltage Correction Tuning].
Usually it is not necessary to change this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness for online resistor tuning. Set this parameter to approximately 1.000 to enable
the function. The function is disabled when the value is 0.000.
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression gain for the low speed range.
V/f CL-V/f OLV CLV AOLV
Sets the response gain related to changes in the load.
V/f CL-V/f OLV CLV AOLV
Sets the speed calculation gain during usual operation. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the speed calculation gain during a speed search.
V/f CL-V/f OLV CLV AOLV
Sets the speed range to operate with the pull-in current command. Drive rated frequency = 100%
value. If there is a large quantity of oscillation when you operate in the low speed range, increase the
setting value.
V/f CL-V/f OLV CLV AOLV
Usually it is not necessary to change this setting. Sets the hysteresis level for Switching Speed set in
n7-10 [Pull-in Current Switching Speed].
When the speed is lower than n7-10 + n7-11 during acceleration, the drive enables pull-in current.
Note:
• When the drive accelerates, it enables these settings:
–Motor speed ≤ n7-10 + n7-11: n8-51 [Pull-in Current @ Acceleration]
–Motor speed > n7-10 + n7-11: b8-01 [Energy Saving Control Selection]
• If there is a large quantity of oscillation when you operate in the low speed range, increase the
setting value.
• When it is most important to save energy in the low speed range, decrease the setting value.
V/f CL-V/f OLV CLV AOLV
Sets a time to enable the pull-in current commands.
If there is a large quantity of oscillation at speeds around n7-10 [Pull-in Current Switching Speed],
decrease the setting in 20 ms decrements.
V/f CL-V/f OLV CLV AOLV
Sets the function to adjust for changes in the motor resistance value caused by changes in the
temperature.
