Speed Curve Generation
The MPU handles the digital speed pattern generation. It takes in information from the remote
processors and then outputs an analog speed demand to the motor drive system.
D/A Ports
Two D/A (Digital to Analog Converter) ports are provided on the MPU board. The first D/A port is
used to output an analog pattern to the motor drive system. The second D/A port is the Pretorque
Signal Output for the MagneTek Drive. It is internally adjusted during the pretorque setup. The D/A
ports provides electrical isolation between the motor control section and the controller's
microprocessor.
The first D/A port outputs a voltage proportional to the desired car speed. This voltage is updated
continuously by the main processor, and is dependent upon the user-entered speed curve
parameters, the target floor, the present speed and position of the car. All car speed outputs are
based on feedback from the Car Top Encoder, and are initiated through hoistway slow down devices.
High speed pattern to the drive system is adjusted for 7 volts at contract speed, positive in the up
direction and negative in the down direction. The maximum speed attained on any run is determined
by the user-entered sped curve parameter settings, floor to floor distances and the motor control
system. Final speed (leveling) is a user entered speed curve parameter setting.
During the slowdown portion of each run, the ideal "S" curve (calculated using the user entered speed
curve parameters) is altered based on actual car position and speed information. This "curve
correction" will provide the same ride on all runs, providing that the overall system response is rapid
enough.
Serial Communication Ports
Four (4) serial communication ports are provided on the MPU board. The J13 & J14 serial ports can
be used to allow the new Ultra 2000 car to communicate with an existing MicroFlite dispatching
system. The P1 & P2 serial ports are reserved for communicating with Building Management
Systems & Lobby Display computers.
Video Port
The standard composite video port drives the in controller monitor. This signal is a standard video
output. It allows the user the flexibility of plugging a VCR in to record the I/O screen to determine the
cause of intermittent failures.
Expansion Port
An expansion port has been provided to allow for expanding the standard 45 inputs and 40 outputs
that are contained on the relay board. The expansion port can accommodate a large number of
additional I/O, making the system adaptable to virtually any necessary configuration.
13.1.3 Intelligent Car Station Board
All inputs and outputs inside the cab are controlled by the Intelligent Car Station board. This board
can be mounted inside the car station, in the toe guard, or on the car top. The board can take up to
48 inputs and 48 outputs. If more than 48 inputs or outputs are needed in the car, expansion boards
