Description
V/f OLV/PM EZOLV OLV/PM
Sets the oscillation suppression gain for the low speed range.
V/f OLV/PM OLV/PM EZOLV
Sets the response gain related to changes in the load.
V/f OLV/PM EZOLV OLV/PM
Sets the speed calculation gain during usual operation. Usually it is not necessary to
change this setting.
V/f OLV/PM EZOLV OLV/PM
Sets the speed calculation gain during a speed search.
Note:
When E9-01 = 1 [Motor Type Selection = Permanent Magnet (PM)], the default
setting is 0 Hz and the setting range is 1.0 - 80.0 Hz.
V/f OLV/PM OLV/PM EZOLV
Parameter n8-51 [Pull-in Current @ Acceleration], is in effect when the output frequency
is ≤ n7-10, where the speed is set as a percentage of rated speed.
Note:
• The value set in n8-51 [Pull-in Current @ Acceleration] is enabled for speeds that
are not higher than n7-10 during deceleration. The value set in b8-01 [Energy Saving
Control Selection] is enabled for speeds higher than n7-10.
• 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 OLV/PM EZOLV OLV/PM
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:
• The value set in n8-51 [Pull-in Current @ Acceleration] is enabled for speeds that
are not higher than n7-10 + n7-11 during acceleration. The value set in b8-01 [Energy
Saving Control Selection] is enabled for speeds higher than n7-10 + n7-11.
• 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 OLV/PM EZOLV OLV/PM
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 decrements of 20 ms.
V/f OLV/PM EZOLV OLV/PM
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 OLV/PM OLV/PM EZOLV
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 OLV/PM EZOLV OLV/PM
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 OLV/PM EZOLV OLV/PM
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.
