Description
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.
0 : Invalid
1 : Valid (Only 1 time)
2 : Valid (Every time)
Description
V/f CL-V/f OLV CLV AOLV
Sets the Initial Rotor Position Estimated Current as a percentage where E5-03 [PM Motor
Rated Current (FLA)] = 100%. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the current at the time of polar attraction as a percentage where E5-03 [PM Motor
Rated Current (FLA)] = 100%. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the length of the Current Starting Time, which is used for Z Pulse Offset Tuning.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the length of the Polar Attraction Time, which is used for Z Pulse Offset Tuning.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the proportional gain for current regulator q-axis control when the drive estimates the
initial pole. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the integral time for current regulator q-axis control when the drive estimates the
initial pole. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the q-axis limit of the current regulator when the drive estimates the initial pole.
Usually it is not necessary to change this setting.
