9.4 Renewed request for "learning" limit positions
If the limit positions have been pre-taught when using electronic limit switches, but these are not suitable for
the respective door, the learning process for limit positions can be requested again
The following parameter must be set for this:
P.210 = 5 Renewed teaching of all limit positions
9.5 Boost / increase in performance forlow speeds
Boost is used to increase the power of the drives at low speed. Too much or too little boost can result in
improper door operation. The boost adjustment range is 0-30%. Too much boost will result in an over current
fault (F.510/F.410). In this case the boost must be reduced.
If the boost is low or 0 and the motor still does not have sufficient force to move the door, the boost must be
increased.
Due to the large number of door types, the correct setting for boost must be determined empirically.
1. Open parametrization mode by pressing the
STOP and
OPEN keys simultaneously.
2. Open Boost parameter by pressing the
arrow keys. Boost can be set separately for OPEN and
CLOSE.
Boost for opening: P.140
Boost for closing: P.145
3. Open the parameter by momentarily pressing
STOP and use the
arrow keys to change it in
small steps of max. 5, then save by pressing
STOP (longer).
4. After changing the boost, exit parametrization mode by pressing the
STOP button for a long time
and test the setting in run mode.
You can use diagnostic parameter P.910 = 2 to display the actual motor current. The boost should be
set so that the motor current remains as low as possible.
