Controllers
4.7 Operating and parameterizing controllers
When reversing from the opening to the closing direction, the door is braked with the
reversing ramp OPEN_CLOSE, and starts the closing movement with the acceleration ramp
CLOSE.
Note
The acceleration ramps are limited in accordance with the door mass and the parameterized
opening and closing forces.
4.7.4.2
Forces
The following forces and currents can be configured for the driving curve:
Idle torque open
Idle torque in the door position OPEN.
This parameter is in effect when an open command is set and the door is in the OPEN
position.
The current generates an idle torque against the end position of the door in the opening
direction.
Adjustment ranges
The parameter can be adjusted in accordance with the adjustment ranges of the parameters
(see section Profiles and adjustment ranges (Page 136)). The value of the parameter must
be selected so that the door is held in the OPEN position. This prevents the door from
oscillating in the end position.
Idle torque close
Idle torque in the door position CLOSED.
This parameter is in effect when a close command is set and the door is in the CLOSED
position.
The current generates an idle torque against the end position of the door in the closing
direction.
Adjustment ranges
The parameter can be adjusted in accordance with the adjustment ranges of the parameters
(see section Profiles and adjustment ranges (Page 136)). The value of the parameter must
be selected so that the door is held in the CLOSED position. This prevents the door from
oscillating in the end position.
Peak torque close
The peak torque close presses the door against a door cutter.
If an obstruction is detected within a tolerance range of 1 cm around the CLOSED position,
then the peak torque close is applied for approx. 2 seconds.
