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.
This parameter is also effective when the special parameter "Idle torque without door
command" is switched on 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 169)). 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.
Note
The "Idle torque (power) OPEN" has to be adjusted in such a way that the door cannot be pulled
out of the OPEN position, e.g. through a counterweight or rubber buffers in the end stop. (See
the section Oscillation protection (Page 48)).
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.
This parameter is also effective when the special parameter "Idle torque without door
command" is switched on 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 169)). 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.
Note
The "Idle torque (power) CLOSE" parameter has to be adjusted in such a way that the door cannot
be pushed from the CLOSE position, for example through the spring of the closing mechanism
or rubber buffers in the end stop. (See the section Oscillation protection (Page 48)).
To ensure an emergency release, observe the section Emergency release (Page 52).
Peak torque close
The peak torque close presses the door against a door cutter.
