Line-to-Line Motor
Resistance Online Tuning
Tunes the line-to-line motor resistance continuously during
operation.

n8: Permanent Magnet (PM) Motor Control
Use n8 parameters to control the PM motor control.

Speed Feedback Detection
Control Gain
Sets the gain for internal speed feedback detection control.
This parameter does not typically require adjustment.
Increase this setting if hunting occurs.
Decrease to lower the response.

Pull-In Current
Compensation Time
Constant
Sets the time constant to make the pull-in current and actual
current value agree.
Decrease the value if the motor begins to oscillate.
Increase the value if it takes too long for the current reference
to equal the output current.

n8-48 Pull-In Current
Defines the amount of current 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.

n8-51 Acceleration Pull-In Current
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.
0 to 200% 50% − − A 53E 211
n8-54
Voltage Error Compensation
Time Constant
Sets the time constant for voltage error compensation. Adjust
the value when
hunting occurs at low speed.
hunting occurs with sudden load changes. Increase in steps
of 0.1 or disable the compensation by setting n8-45 to 0.
oscillations occur at start. Increase the value in steps of 0.1.

Output Voltage Limit
Sets the limit for the output voltage. Adjustment is normally
needed only if the input voltage is below the n8-62 set value.
In this case set n8-62 to the input voltage.
