n
n8-45: Speed Feedback Detection Control Gain (PM OLV)
Sets the gain for internal speed feedback detection control. Although this setting rarely needs to be changed, adjustment may be necessary under the
following conditions:
• Increase this setting if motor oscillation occurs.
• Decrease this setting when there is a fair amount of speed fluctuation due to the load.
• Lower this setting in increments of 0.05 to decrease how responsive the drive is.

n
n8-47: Pull-In Current Compensation Time Constant (PM OLV)
Sets the gain in units of 0.1 seconds to compensate for the phase margin.
Although this setting rarely needs to be changed, adjustment may be necessary under the following conditions:
• Increase this setting when it takes too long for the reference value for the Pull-In Current to match the target value.
• Decrease this setting if motor oscillation occurs.

n8-47 Pull-In Current Compensation Time Constant (PM OLV) 0.0 to 100.0 s 5.0 s
n
n8-48: Pull-In Current (PM OLV)
Tells the drive the amount of current to be provided to the motor during no load operation at a constant speed. Set as a percentage of the motor rated
current.
Increase this setting when hunting occurs while running at a constant speed.
• If the motor is unstable when operating at constant speeds, then slightly increase this setting.
• If there is too much current when drive a light load at a constant speed, then raise this level slightly.

n8-48 Pull-In Current (PM OLV) 20 to 200% Determined by E5-01
n
n8-49: d Axis Current for High Efficiency Control (for PM)
Sets the amount of d axis current when using Energy Saving control as a percentage of the motor rated current. For IPM motors only.
Although this setting seldom needs to be changed, please note the following:
• If motor operation is unstable when driving heavy loads, try lowering this setting.
• If motor parameters (E5) have been changed, this value will be reset to 0.
No. Parameter Name Setting Range Default
n8-49 d Axis Current for High Efficiency Control (for PM) -200.0 to 0.0% Determined by E5-01
n
n8-51: Acceleration Time Pull-In Current (for PM OLV)
Sets the pull-in current during acceleration as a percentage of the motor rated current (E5-03). Set to a high value when more starting torque is needed.
Adjustments to this setting may help in the following situations:
• Increase this setting when a large amount of starting torque is required.
• Lower this setting if there is excessive current during acceleration.
