Stop Option Control (Stop Option); Direct Current Braking Control - Dc Braking - GE AV-300i User Manual

1.11 STOP OPTION CONTROL (STOP OPTION)

1.11.1 Direct Current Braking Control - DC Braking

The Function allows to stop the motor with a direct current braking.
The current injection can be activated via an external command, via the DCbrake cmd src source or automati-
cally via an internal command when the stop command is performed. Such command can be activated by setting
DCbrake mode = "at stop".
It is possible to have simultaneously both the internal and the external command. They both work on a OR logic.
Furthermore, the function is made of:
- a waiting phase between the command emission and the duration of the programmable injection
- a direct current injection phase, whose intensity and duration can be programmed.
Via DCBrake delay it is possible to set the waiting phase between the command and the injection duration.
N !
OTE
If the external command is a pulse shorter than the programmed injection time, the injection
phase lasts for the programmed time. If the external command is a pulse longer than the
programmed injection time, the injection phase lasts till the end of the external command.
With DCBrake duration it is possible to set the current injection duration while DCBrake current allows to set
the current intensity.
