Meiller (Germany) presented at the Interlift 2017 its CANopen Lift door unit. It supports two energy-saving modes.
The Midrive (Meiller intelligent Drive) door unit complies with the CiA 417 CANopen application profile for elevators. It comprises the CANopen Lift interface and the controllers for the CAN-connected motors. They communicate via a second CAN interface. There are several motor options available (200 kg, 400 kg, 800 kg).
The door unit can be connected via CANopen Lift to the door controller and other CANopen Lift devices including further door units. Optionally, the doors can be opened manually, for example, in case of an emergency. There are two power-saving modes implemented, Eco and Eco-Plus. The smartphone apps for door commissioning are available. This involves the use of pre-defined QR codes to configure the door unit on site.
