MLC interface management
5.4.1
PC01: MLC commands check mode
This parameter defines how the door drive checks the commands coming from MLC. The following table
shows the possible options:
Parameter value
Active command status
Notes
00 = level
(default value)
Signal level always checked
The command is considered active until the input
signal is closed to the common voltage. During
parking the command can be removed
01 = level also during
parking
Signal level always checked
As the previous, but in addition the command is
checked also during parking. If it is removed, the
controller removes the related active parking output
02 = edge
One activation edge of the command is enough to
generate a complete door movement. Suggested only
when strictly necessary (old MLC compatibility)
5.4.2
PC02: reaction of door drive if no MLC command
This parameter defines the behaviour of the door drive when no commands are present from MLC, when
the door is at intermediate position (not completely closed and not completely opened).
Parameter value
Notes
00 = instant stop
(default value)
The controller, in case no commands are present, stops immediately the door and
keeps the actual position with low torque applied to the motor.
01 = low speed + stop
The controller completes the current movement with reduced speed until the final
position is reached
02 = low speed cycle
The controller executes a reduced speed cycle: at the commands interruption, the door
opens completely with reduced speed, remains opened for 30s, then closes completely
with reduced speed (evacuation oriented).
5.4.3
PC03: Alarm enabling if no MLC commands
This parameter allows to activate an warning code (AL01), in case no commands from the MLC are present,
to store the number of this event type. Not suggested if MLC usually removes commands (i.e. during
parking).
Parameter value
Note
00 = disabled
(default value)
Alarm AL01 not enabled
01 = enabled
Alarm AL01 enabled
