Expert
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.
• When you increase the setting value, you can do a speed search of a motor rotating at a high frequency. If the setting value is too high, the
calculated speed will oscillate and a restart will fail. Decrease the setting value in these conditions.

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.

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.

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.

YASKAWA TOEPYAIHV6002A HV600 Drive Programming
V/f OLV/PM OLV/PM EZOLV
Sets the speed calculation gain during a speed search.
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.
V/f OLV/PM OLV/PM EZOLV
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.
V/f OLV/PM EZOLV OLV/PM
Sets a time to enable the pull-in current commands.
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.
