- the engine control unit controls the engine speed depending on the Command signals they from the driving program control unit receives.
- the engine control unit contains a tachometer or tachometer Determination of the actual speed. It also contains one Speeds memory in which speeds are stored, for example a start-up characteristic and a braking characteristic to give a smooth Run up and slow down the cabin.
- Speeds memory in which speeds are stored, for example a start-up characteristic and a braking characteristic to give a smooth Run up and slow down the cabin.
- the control of a converter takes place Motor of the drive unit with a corresponding frequency supplied, which specifies the desired speed.
- the motor control unit contains a converter Has power section which variable high currents It delivers frequency for the electric motor cheap if that from the engine control unit to the Motor leading cables are short to high frequency contamination to avoid as far as possible by radiation from the cable. Therefore, the power control of the engine is from the driving program control is spatially separated. About the Tow cables leading to the cabin are used exclusively Transfer data and electricity for cabin lighting and the like
- the driving program control unit is preferably from Interior of the cabin accessible from. Here you can a door or hatch are located with a key can be opened to access the control unit to obtain. Such a control unit is for the fitter very easy and convenient to reach.
- the driving program control unit is also within the scope of the invention to be installed elsewhere in the cabin, for example on the cabin roof.
- the invention is a first flexible cable provided that of those on each floor installed input devices leads to the cabin.
- a second flexible cable is also provided leads from the cabin to the drive unit.
- the first and the second cable are looped single cable harness summarized. Thereby it is avoided that numerous mutually independent Hang cable loops in the elevator shaft.
- the elevator shown has an elevator shaft 10 on, each with a Door opening 11 is provided.
- a frame 12 is mounted, which vertical rails 13 for guiding a carriage 14.
- the frame 12 is located on the side facing away from the door openings 11 Rear wall or on a side wall of the shaft 10th
- the carriage 14 has one transversely in the shaft 10 protruding cantilever arm 15 on which the cabin 16 rests.
- the car 16 is a common elevator car, which can accommodate several people and which has a tableau Contains 17 with input keys that the user can enter the desired floor.
- the carriage 14 hangs on a rope 18, which over the traction sheave 19 of a drive unit 20 runs.
- the Drive unit 20 includes an electric motor 28 which the traction sheave 19 rotates. As a result, the rope 18 of the traction sheave 19 moves up or down.
- the rope wraps around the traction sheave 19 in a groove and be opposite end is with a counterweight 21 complained that hangs in the shaft.
- the drive unit 20 is operated by a driving program control unit 22 controlled in or on the cabin 16 is arranged.
- the drive program control unit 22 forms the "brain" of the elevator. It receives request signals of input devices 23 to the Door openings 11 are installed, and command or Target signals from the panel 17 inside the cabin 16. Depending on these request and target signals the driving program control unit sets the sequence in which the cabin moves to the individual floors.
- the drive program control unit 22 controls the Drive unit 20.
- the cable harness 24 contains a first cable 25 from the input devices 23 leads to the driving program control unit 22, and a second cable 26 from the drive program control unit 22 leads to the drive unit 20. Furthermore the wiring harness 24 can still supply lines and other lines included.
- the driving program control unit 22 is in the present Embodiment housed in a box 27, which is arranged on the outside of the cabin 16 and the inside of the cabin through a flap or door is accessible.
