L3-17: DCBus Regul.Level
No.
Name
(Hex.)
L3-17 DCBus Regul.Level
(0462)
Note:
This value is initialized when E1-01 [Input AC Supply Voltage] is changed.
Sets this parameter for any of the following circumstances.
• L3-11 = 1 [Overvolt Supression Select = Enabled].
• L3-04 = 1 [StallP@Decel Enable = Enabled] and L3-50 = 1 [StallP@Decel Mode = Automatic Decel
Reduction].

L3-20: DCBus VoltAdj Gain
No.
Name
(Hex.)
L3-20 DCBus VoltAdj Gain
(0465)
Expert
Set one of these parameters to enable L3-20:
• L2-29 = 2 [KEB Method = Single KEB2 Ride-Thru]
• L3-04 = 1 [StallP@Decel Enable = Enabled] and L3-50 = 1 [StallP@Decel Mode = Automatic Decel
Reduction]
• L3-11 = 1 [Overvolt Supression Select = Enabled]
• H1-xx = 42 or 43 [MFDI Function Select = KEB Thru2 NC or KEB Thru2 NO]
Note:
• If stall prevention during deceleration function causes ov [Overvoltage] and Uv1 [DC Bus Undervoltage] faults when you start
deceleration and L2-29 = 1, H1-xx = 42 or 43, or L3-04 = 1 and L3-50 = 1, gradually increase this parameter in 0.1-unit increments. If
the setting value is too high, it can cause large speed or current ripples.
• If sudden increases in the regenerative load cause ov faults and L3-11 = 1, gradually increase this parameter in 0.1-unit increments. If
the setting value is too high, it can cause large speed or current ripples.

L3-21: OVSup Acc/Dec Gain
No.

(Hex.)
L3-21 OVSup Acc/Dec Gain
(0466)
Expert
Set one of these parameters to enable L3-21:
• L2-29 = 2 [KEB Method = Single KEB2 Ride-Thru]
• L3-04 = 1 [StallP@Decel Enable = Enabled] and L3-50 = 1 [StallP@Decel Mode = Automatic Decel
Reduction]
• L3-11 = 1 [Overvolt Supression Select = Enabled]
• H1-xx = 42 or 43 [MFDI Function Select = KEB Thru2 NC or KEB Thru2 NO]
Note:
• If stall prevention during deceleration function causes ov [Overvoltage] and Uv1 [DC Bus Undervoltage] faults when you start
deceleration and L2-29 = 1, H1-xx = 42 or 43, or L3-04 = 1 and L3-50 = 1, gradually increase this parameter in 0.1-unit increments. If
the setting value is too high, it can cause large speed or current ripples.
• If sudden increases in the regenerative load cause ov faults and L3-11 = 1, gradually increase this parameter in 0.1-unit increments. If
the setting value is too high, it can cause large speed or current ripples.
