P-82: DCS management during Unlocking jam retries
This parameter allows to manage the DCS signal when door is performing the unlocking retries to open the
clutch. The door drive implements the management of retries in case of:
Door opening: at the beginning of door opening, the door drive opens the clutch, but in case of jam
the door drive recloses the clutch (returns to door locked position) activate AL03 warning, and after
1s retries to open the clutch. After the 5
rd
retry the door drive stops in door locked position.
Door closing: at the end of door closing, the door drive close the clutch, but in case of jam the door
drive reopen the clutch (returns to door unlocked position) activate AL03 warning, and after 1s
retries to close the clutch. After the 5
rd
retry the door drive stops in door unlocked position.
During the unlocking retries the door drive can be configured to toggle the DCS signal, to inform the lift
controller that the retries are in progress. The following table shows the settings.
Parameter value
Notes
00 = OFF
(
default value
)
The DCS signal never changes status during locking/unlocking retries.
-
Unlocking retries: the DCS signal is always INACTIVE
01 = ON
The DCS signal changes status during locking/unlocking retries.
-
Unlocking retries: the DCS signal is INACTIVE when the door is opening the
clutch, and ACTIVE when the door is reclosing the clutch

P-86: Storage of estimated motor temperature
The door drive estimates the motor temperature with I2T algorithm, since there isn’t physical thermal
sensor on the motors. This parameter allows to activate the storage of the estimated motor temperature,
to keep the last value of the estimated motor temperature at the controller start-up. The following table
shows the settings.
Parameter value
Notes
00 = DISABLED
The estimated motor temperature is not stored in the internal memory. Every time
that the door drive is switched off, at the next power-on the estimated motor
temperature is set to 25°C. Then the motor temperature is updated based on the
door drive algorithm.
01 = ENABLED
(
default value
)
The estimated motor temperature is stored periodically (every 30’) in the internal
memory. Every time that the door drive is switched off, at the next power-on the
estimated motor temperature is set last saved value. Then the motor temperature is
updated based on the door drive algorithm.
