L3-21
Accel/Decel Rate
Calculation Gain
Sets the proportional gain used to calculate the deceleration
rate during KEB, ov suppression function and Stall
Prevention during deceleration (L3-04 = 2).
This parameter does not typically require adjustment.
Increase the value in steps of 1.0 if overcurrent and
overvoltage occur.

Deceleration Time at Stall
Prevention during
Acceleration
Sets the deceleration time used for Stall Prevention during
acceleration in Open Loop Vector Control for PM motors.
When set to 0, the drive decelerates at the normal deceleration
time.

Automatic Reduction
Selection for Stall Prevention
during Run
0: Sets the Stall Prevention level throughout the entire
frequency range to the value in parameter L3-06.
1: Automatically lowers the Stall Prevention level in the
constant output range. The lower limit value is 40% of L3-06.

Motor Acceleration Time for
Inertia Calculations
Sets the time needed to accelerate the uncoupled motor at
rated torque from stop to the maximum frequency.
Setting the drive capacity to parameter o2-04 or changing
E2-11 will automatically set this parameter for a 4-pole
motor.

L4: Frequency Detection
Use L4 parameters to configure frequency detection operation.

Speed Agreement Detection
Level
These parameters configure the multi-function output (H2-
 = 2, 3, 4, 5) settings "Speed Agree 1", "User Set Speed
Agree 1", "Frequency Detection 1," and "Frequency
detection 2".
Parameter L4-01 sets the level while parameter L4-02 sets
the hysteresis for the Speed Detection Output Function.

Frequency Reference Loss
Detection Selection
Sets operation when the frequency reference is lost (reference
drops 90% or more within 400 ms).
0: Stop - Drive will stop.
1: Run at L4-06 Level - Drive will run at the percentage set
in L4-06 of the frequency reference before loss.

L5: Fault Reset
Use L5 parameters to configure Automatic Restart after fault.
L5-01
Number of Auto Restart
Attempts
Sets the counter for the number of times the drive attempts
to restart when one of the following faults occurs: GF, LF,
oC, ov, PF, rH, rr, oL1, oL2, oL3, oL4, Uv1.
Parameter L5-05 determines the how the restart counter is
incremented.
When the drive operates without fault for 10 minutes, the
counter will be reset.
