5.9 Group 8: Special Parameters

8 - 00 DC Fékezési feszültségi szint Factory Setting: d 0

Settings d 0 to d30% Unit: 1%

! This parameter determines the level of DC Braking Voltage Level output to the motor

during start-up and stopping. When setting DC Braking Voltage, the Maximum Output

Voltage (Pr.1-02) is regarded as 100%. It is recommended to start with a low DC Braking

Voltage Level and then increase until proper holding torque has been attained.

8 - 01 DC Fékezési ideje indításnál Factory Setting: d 0.0

Settings d 0.0 to d 60.0 sec Unit: 0.1sec

! This parameter determines the duration of time that the DC Braking Current will be

applied to the motor during the AC drive start-up.

8 - 02 DC Fékezési idő a megállás során Factory Setting: d 0.0

Settings d 0.0 to d 60.0 sec Unit: 0.1 sec

! This parameter determines the duration of time that the DC braking voltage will be

applied to the motor during stopping. If stopping with DC Braking is desired, then

Pr.2-02 must be set to RAMP stop (d 0).

8 - 03

DC fékezés indítási pontja

Factory Setting: d 0.0

Settings d 0.0 to d 400Hz Unit: 0.1Hz

! This parameter determines the frequency when DC Braking will begin during

deceleration.

NOTE: 1. DC Braking during Start-up is used for loads that may move before AC drive

starts, such as fans and pumps. These loads may also be moving in the wrong

direction. Under such circumstances, DC Braking can be executed to hold the

load in position before applying a forward motion.
