Motor Overheat Protection
L1-01
Motor
Overload
Prot. Sel.
Sets the motor overload protection.
0: Disabled
4: PM motor with variable
torque
L1-02
Motor
Overload
Prot. Time
Sets the motor overload protection
time in min. Normally no change is
necessary.
Stall Prevention
L3-01
Stall
Prevention
Selection
during
Accelera-
tion
0:Disabled
-
Motor accelerates at
active acceleration rate and may
stall with too heavy load or too
short accel time.
1:General Purpose - Hold
acceleration when current is
above L3-02.
2:Intelligent - Acceleration in the
shortest possible time.
L3-02
Stall Prev.
Level dur-
ing Accel.
Sets the current level for stall pre-
vention during acceleration.
L3-04
Stall Prev.
Selection
during
Decel.
0:Disabled - Deceleration as set.
OV might occur.
1:General Purpose - Deceleration
is hold if DC bus voltage rises
high.
L3-05
Stall Prev.
Selection
during Run
0:Disabled - Motor stall or
overload might occur.
1:Decel Time 1 - Reduce speed
using C1-02.
L3-06
Stall Prev.
Level dur-
ing Run
Sets the current level at which stall
prevention during run starts to
operate.
Permanent Magnet (PM) Motor Control
n8-45
Speed Feed-
back Detec-
tion 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 Cur-
rent Com-
pensation
Time Con-
stant
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 out-
put current.
n8-48
Pull-in Cur-
rent
Defines the amount of current pro-
vided 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.
n8-49
Load Cur-
rent
Sets the amount of d-axis current
when using Energy Saving control.
n8-51
Accelera-
tion 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 Com-
pensation
Time Con-
stant
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
diable the compensation by setting
n8-45 to 0.
-oscillations occur at 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.
1: between 1:10 to 1:30.
2: between 1:30 to 1:50.
3: higher than 1:50.
n8-62
<1>
Output
Voltage
Limit
Sets the limit for the output volt-
age. Adjustment is normally
needed only if the input voltage is
below the n8-62 set value. In this
case set the n8-62 value to the input
voltage
