Yaskawa CIMR-PU2A0081 [234/548] L2 02 momentary power loss ride thru time
Parameter Name Setting Instructions
KEB Mode (L2-29)
0 1 2 3
L3-21
Accel/Decel Rate
Calculation Gain
Reduce L3-21 in steps of 0.05 if there is a fairly large speed or current
ripple.
Decreasing this setting too much can cause a slow DC bus voltage
control response, and may lead to problems with overvoltage or
undervoltage.
NO YES NO NO
L3-24 Motor Acceleration Time Set the motor acceleration time as described on page 240. NO YES NO NO
L3-25 Load Inertia Ratio Set the load/inertia ratio as described on page 240. NO YES NO NO
n
L2-02: Momentary Power Loss Ride-Thru Time
Sets
the maximum time allowed to ride
through a power loss. If power loss operation exceeds this time, the drive will attempt
to accelerate back to the frequency reference. This parameter is valid if L2-01 = 1 or 3.
Note: The amount of time the drive is capable of recovering after a power loss is determined by the capacity of the drive. Drive capacity determines
the upper limit for L2-02.
No. Name Setting Range Default
L2-02 Momentary Power Loss Ride-Thru Time 0.0 to 25.5 s Determined by o2-04
n
L2-03: Momentary Power Loss Minimum Baseblock Time
Sets the minimum baseblock time when power is restored following a momentary power loss. This determines the time the
drive waits for the residual voltage in the motor to dissipate. Increase this setting if overcurrent or overvoltage occurs at the
beginning of Speed Search, after a power loss, or during DC Injection Braking.
No. Name Setting Range Default
L2-03 Momentary Power Loss Minimum Baseblock Time 0.1 to 5.0 s Determined by o2-04
n
L2-04: Momentary Power Loss Voltage Recovery Ramp Time
Sets
the time for the drive to
restore the output voltage to the level specified by the V/f pattern after Speed Search. The setting
value determines the time for the voltage to go from 0 V to the maximum voltage.
No. Name Setting Range Default
L2-04 Momentary Power Loss Voltage Recovery Ramp Time 0.0 to 5.0 s Determined by o2-04
n
L2-05: Undervoltage Detection Level (Uv)
Determines the voltage at which a Uv1 fault is triggered or at which the KEB function is activated. This setting rarely needs
to be changed.
No. Name Setting Range Default
L2-05 Undervoltage Detection Level
150 to 210 Vdc
<1>
Determined by
E1-01
<2>
<1> Values are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<2> The default setting for 400 V class drives depends on whether the drive input voltage is over 400 V or under 400 V.
Note: 1. Install an AC reactor option on the input side of the power supply when setting L2-05 below the default value to prevent damage to
drive circuitry.
2. If using KEB Ride-Thru and
L2-05 is set too low, then undervoltage in the DC bus (Uv1) will be triggered before KEB Ride-Thru can
be executed. Take caution not to set this value too low.
n
L2-06: KEB Deceleration Time
Sets the time to decelerate from the frequency reference at the time KEB Ride-Thru was initiated to zero speed. This setting
can be used only when L2-29 = 2 ( System KEB Ride-Thru 1).
No. Name Setting Range Default
L2-06 KEB Deceleration Time
0.00 to 6000.0 s
<1>
0.00 s
<1> Setting range is determined by the accel/decel time units set in C1-10. If the time is set in units of 0.01 s (C1-10 = 0), the setting range becomes
0.00 to 600.00 s.
