Nudge

Description of function
If a "Nudge" command is present, the reversing unit is deactivated. The input signals CLOSE and
NUDGE must be active so that the NUDGE operating state is only effective in the closing
direction. When an obstacle is detected, the motor current after 1 s is reduced to the rated motor
current.
Connection
The "Nudge" function is connected to "Input 2" (X6). For more, see also section Digital input
signals (Page 68).
The function is only active in conjunction with the CLOSE input signal.

Restart after power failure

Description of function
After a power failure, the controller has to redetermine the end positions of the door travel
(initial mode). To do this, the door travels at reduced speed (initial speed) until the controller has
detected the OPEN and CLOSED end positions. The door then resumes traveling at normal speed.
Changes in the driving curve parameters are applied in the initial mode at a standstill.
