B.2 Parameter Table
No. Name
Selects the Stall Prevention method used to prevent
excessive current during acceleration.
Stall 0: Disabled - Motor accelerates at active acceleration
Prevention rate. The motor may stall if load is too heavy or accel
L3-01 Selection time is too short.
during 1: General Purpose - When output current exceeds
Acceleration L3-02 level, acceleration stops. Acceleration will
continue when the output current level falls below the
L3-02 level.
Stall Used when L3-01 = 1.
Prevention 100% is equal to the drive rated current.
L3-02
Level during Decrease the set value if stalling or excessive current
Acceleration occurs with default setting.
When using a braking resistor, use setting "0".
0: Disabled - The drive decelerates at the active
deceleration rate. If the load is too large or the
deceleration time is too short, an ov fault may occur.
Stall 1: General Purpose - The drive decelerates at the
Prevention active deceleration rate, but if the main circuit DC bus
L3-04 Selection voltage reaches the Stall Prevention level,
during deceleration will stop. Deceleration will continue
Deceleration once the DC bus level drops below the Stall
Prevention level.
4: Overexcitation Deceleration - Decelerates with the
flux level determined by n3-13 (Overexcitation
Gain).
Selects the Stall Prevention method to use to prevent
drive faults during run.
0: Disabled - Drive runs a set frequency. A heavy load
may cause the drive to trip on an oC or oL fault.
1: Decel Time 1 - The drive will decelerate at Decel
Stall Time 1 (C1-02) if the output current exceeds the level
Prevention set by L3-06. Once the current level drops below the
L3-05
Selection L3-06 level, the drive will accelerate back to its
during Run frequency reference at the active acceleration rate.
2: Decel Time 2 - Same as setting 1 except the drive
decelerates at Decel Time 2 (C1-04).
When output frequency is 6 Hz or less, Stall
Prevention during run is disabled regardless of the
setting in L3-05.
Enabled when L3-05 is set to "1" or "2". 100% is
Stall
equal to the drive rated current.

occurs with the default settings.
Run
Upper level is determined by C6-01 and L8-38.
Speed These parameters configure the multi-function output
Agreement (H2- 01 = 2, 4, 5) settings "Speed Agree 1",
