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.

n8-47
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.

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 ar start. Increase the value in steps of 0.1.

n8-55 Load Inertia
Sets the ratio between motor and machine inertia.
0: less than 1:10.

2: between 1:30 to 1:50.
3: higher than 1:50.

n8-62 <24> 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.
