frequency and stop work.
For inverter with build in braking unit (under than AC90-T3-018T, braking resistance (optional) can be used. When DC
bus voltage is over
[FA.08]
energy braking act voltage, inverter begins to carry out the energy braking act.
For inverter without build in braking unit (upper than AC90-T3-022T), braking unit and braking resistance can be
selected. It is mainly used for occasion that need quick braking while stop.
1: Free stop
Inverter stop output while receiving the stop order. Usually, it cooperates with exterior machine hold brake.

Initial frequency of stop DC braking:
While inverter DEC to this frequency, it will stop output and start DC braking.
Stop DC braking current:
It is the current that inverter give motor while DC braking. It is based on the output rated
current of the inverter. DC braking can afford 0 speed torque. It is uaually used for improve stop accuracy and quick
stop. It can’t be used for DEC braking for normal running.
Waiting time of stop DC braking:
It is the time for waitting to DC braking while inverter DEC to initial frequency of stop
DC braking and stop output.
Stop DC braking duration:
It is DC braking current holding time after stop. It is no DC braking process while braking
time is 0.0s.

Start ACC rate of S curve:
It is the rate while start ACC. The smaller the rate is, the ACC S surve is sharper. Othwise,
The bigger the rate is, the ACC S surve is more like a beeline. If you want it ACC more smoothly, you can reduce the
rate and prolong ACC time.
Start DEC rate of S curve:
It is the rate while start DEC. The smaller the rate is, the DEC S surve is sharper. Othwise,
The bigger the rate is, the ACC S surve is more like a beeline. If you want it DEC more smoothly, you can reduce the
rate and prolong DEC time.
