L3-04
Stall
Prevention
Selection
during
Deceleration
0: Disabled. Deceleration at the active
deceleration rate. An ov fault may occur.
1: General purpose. Deceleration is
paused when the DC bus voltage exceeds
the Stall Prevention level.
2: Intelligent. Decelerate as fast as possible
while avoiding ov faults.
3: Stall Prevention with braking resistor.
Stall Prevention during deceleration is
enabled in coordination with dynamic
braking.
4: Overexcitation Deceleration. Decelerates
while increasing the motor flux.
5: Overexcitation Deceleration 2. Adjust the
deceleration rate according to the DC bus
voltage.
6: Enabled. Decelerates adjusting the
deceleration rate according to the output
current and the DC bus voltage.
L3-05
Stall
Prevention
Selection
during Run
0: Disabled. Drive runs at a set frequency. A
heavy load may cause speed loss.
1: Decel time 1. Uses the deceleration
time set to C1-02 while Stall Prevention is
performed.
2: Decel time 2. Uses the deceleration time
set to C1-04 while Stall Prevention is
performed.
L3-06
Stall
Prevention
Level during
Run
Enabled when L3-05 is set to 1 or 2. 100%
is equal to the drive rated current.

Tuning prior to Inertia Tuning)
9: ASR Gain Tuning (perform Rotational
Auto-Tuning prior to ASR Gain Auto-
Tuning)
T1-02
Motor Rated
Power
Sets the motor rated power as specified on
the motor nameplate.
T1-03
Motor Rated
Vo l t a g e
Sets the motor rated voltage as specified on
the motor nameplate.
T1-04
Motor Rated
Current
Sets the motor rated current as specified on
the motor nameplate.
T1-05
Motor Base
Frequency
Sets the rated frequency of the motor as
specified on the motor nameplate.
T1-06
Number of
Motor Poles
Sets the number of motor poles as specified
on the motor nameplate.
T1-07
Motor Base
Speed
Sets the rated speed of the motor as
specified on the motor nameplate.
T1-08
PG Number of
Pulses Per
Revolution
Set the number of pulses per revolution for
the PG being used (pulse generator or
encoder).
No. Name Description
T1-09
Motor No-
Load Current
(Stationary
Auto-Tuning)
Sets the no-load current for the motor.
After setting the motor capacity to T1-02
and the motor rated current to T1-04, this
parameter will automatically display the no-
load current for a standard 4 pole
YASKAWA motor. Enter the no-load
current as indicated on the motor test report.
T1-10
Motor Rated
Slip
(Stationary
Auto-Tuning)
Sets the motor rated slip.
After setting the motor capacity to T1-02,
this parameter will automatically display the
motor slip for a standard 4 pole YASKAWA
motor. Enter the motor slip as indicated on
the motor test report.
T1-11
Motor Iron
Loss
Sets the iron loss for determining the
Energy Saving coefficient.
The value is set to E2-10 (motor iron loss)
set when the power is cycled. If T1-02 is
changed, a default value appropriate for the
motor capacity that was entered will appear.
