These parameters are available when using the special Open Loop Vector Control designed for permanent magnet motors.
n8-45: Speed Feedback Detection Control Gain (PM OLV)
n
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.
No.
n8-45 Speed Feedback Detection Control Gain (PM OLV)
n8-47: Pull-In Current Compensation Time Constant (PM OLV)
n
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.
No.
n8-47 Pull-In Current Compensation Time Constant (PM OLV)
n8-48: Pull-In Current (PM OLV)
n
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.
No.

n8-49: d Axis Current for High Efficiency Control (for PM)
n
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.
n8-49 d Axis Current for High Efficiency Control (for PM)
n8-51: Acceleration Time Pull-In Current (for PM OLV)
n
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.
No.
