• Anti-regenerative control sometimes increases the deceleration time.
• When the braking unit is connected, do not use anti-regenerative control. Anti-regenerative control
sometimes acts simultaneously with operation of the braking unit and the deceleration time is not as
set.
•
When the deceleration time is too short, the Main Circuit DC Voltage of the inverter sometimes rises
quickly and anti-regenerative control cannot keep up. In instances like this, set a longer deceleration
time.
Torque Limit (3008Hex-46Hex = 2, 4)
• A feature is that response is high and an overvoltage trip is less likely to occur even by an impact
load. The frequency control value can be adjusted by Anti-regenerative Control Level
(3020Hex-0FHex), and, when the Anti-regenerative Control Level (3020Hex-0FHex) is increased,
frequency control increases.
• This is enabled during acceleration, constant speed and deceleration.
•
The output frequency is controlled until braking torque reaches almost 0 (zero).
• Although Anti-regenerative Control Level (3020Hex-0FHex) can be adjusted, normally adjustment is
not required.
• When the output frequency is limited, an overvoltage trip sometimes is generated as anti-regenera-
tive control is limited. Anti-regenerative capability can be improved by setting a larger Frequency
Rising Limit for Torque Limit (3008Hex-4DHex).
Main Circuit DC Voltage Control (3008Hex-46Hex = 3, 5)
• This is enabled only at deceleration.
