3.1.9.4. Seat motor section
This is the section that manages the interface between the CPU board and seat motor. It receives the
motor command signal from the CPU board, and based on this signal either supplies or cuts off
working voltage to the motor. It generates an alarm signal if any problems occur on the motor
(overcurrent). It receives the motor encoder signal, which it filters, squares and sends to the CPU
board.
This section is missing on the Abdominal Crunch, Lower Back and Leg Press.
On the Leg Extension it interfaces the safety device signal. In normal condition the safety device is a
NC contact, white it is NA in emergency condition. On the other machines, it is a jumper.
The board uses to power the motor 2 10A relays.
3.1.10. LP
DRIVER BOARD
This is the board that manages on the Leg Press the interface between the CPU board, the Bio servo
board and the seat motor.
It receives the motor command signal from the CPU board, and based on this signal either supplies
or cuts off working voltage to the motor. It generates an alarm signal if any problems occur on the
motor:
•
surge current;
•
short-circuit;
•
blocked rotor.
It receives the motor encoder signal, which it filters, squares and sends to the CPU board. It handles
the limit switches in order to prevent that the motor will move in the direction of a pressed limit
switch.
The board is equipped with a programmable chip containing the operating logic, and may be
configured by means of the jumpers:
•
Jumper J1
Handles the encoder power supply voltage: if it is in position 1-2, there are 12 Vdc on pin 1 of
connector CN12, while if it is in position 2-3 there are 5 Vdc.
CAUTION: Keep the jumper in position 2-3.
•
Jumper J2
To enable limit switch management: management is enabled if open, disabled if closed.
CAUTION: Keep the jumper open at all times.
•
Jumper J3
To motor current ripple management: management is enabled if open, disabled if closed.
CAUTION: Keep the jumper open at all times.
