11.3 Pre-limit switch setting
Setting the pre-limit switch can prevent premature or late braking of the door from max. travel speed to
creep speed.
The position of the pre-limit switch is given in increments. The number of increments refers to the distance
between the limit switch and the pre-limit switch.
Creep too long -> reduce pre-limit switch
Creep too short -> increase pre-limit switch
P.222 = Pre-limit switch for limit position Door CLOSE The parameter value specifies the distance to the
absolute limit switch Door CLOSE in increments. The brake ramp "r6" is initiated with the pre-limit
switch. The slope of the ramp is set with parameter P.361 or P.362.
P.232 = Pre-limit switch for limit position Door OPEN: The parameter value specifies the distance to the
absolute limit switch Door OPEN in increments. The pre-limit switch is used to initiate the brake
ramp "r2". The slope of the ramp is set with parameter P.321 or P.322.
If the automatic setting of the pre-limit switch is used (P.216 = 2), the parameters P.222 and
P.232 are changed automatically.
The parameters are also changed if the travel speed or the slope of a ramp is changed as this
results in a restart of the automatic limit switch correction. If these ramps are adjusted manually,
P.216 must be set to less than 2!
11.4 Ramp configuration
The ramps are used by the door controller to change speed, i.e. to accelerate or decelerate.
The ramps are set in milliseconds (ms) or in Hz per second (speed change per second), i.e. the steeper
the ramp, the higher the braking force or acceleration applied to the door. If the ramp is flatter the door is
braked or accelerated more gently.
P.311 / P.312 = start
ramp „r1“: acceleration of the door from 0 Hz to opening speed.
P.321 / P.322 = brake ramp „r2“: deceleration of the door from opening speed to creep speed
P.351 / P.352 = start ramp „r5“: acceleration of the door from 0 Hz to opening speed.
P.361 / P.362
= break ramp „r2“: deceleration of the door from closing speed to creep speed
P.340 / P.342 = Ramp "r-STOP" for opening: deceleration of the door from opening speed to
0 Hz after pressing a STOP key.
P.380 / P.382 = Ramp "r-STOP" for closing: deceleration of the door from closing speed to 0Hz after
pressing a STOP key.
11.5 Correction of the final positions
Parameters P.221 and P.231 can be used to shift the limit positions together with the pre-limit switches.
Changing these parameters in the positive direction results in the limit position being shifted upward.
Changing in the negative direction causes a shift towards the bottom.
