ST9000 | DC braking to hold engine into position
With the ST9000 frequency inverter, it is possible to vary the braking behaviour with a superimposed DC braking voltage, so as to hold the motor in the stop position.
This is an example and the parameters as they need to be adjusted for this function:
The engine will slow down to a value of 20Hz by the DC braking voltage. The DC braking voltage is active for 30 seconds.
| F3.08 = 20 | Desired frequency from the time the DC braking voltage is switched on is 20Hz. |
| F3.09 = 0 | Delay time to turn on the DC power |
| F3.10 = 100 | Percentage share of DC voltage to rated voltage (intensity of the holding force) |
| F3.11 = 30 | The DC braking voltage is held for 30sec |
