VF5
AUTOMATIC DOORS FOR LIFTS
Autoadjustment process.
- Switch OFF the VF and place the doors in closed position.
- Disconnect the inputs (8, 9, 10, 11 and 12) and the priority inputs (26, 21, 25 and 23).
- Switch ON the VF and Push auto-adjustment button (51).
Next 2 movements are to detect which kind of motor it is installed.
- 1st Movement: The door will open 200 mm (If the door instead of opening makes small
rebounds, means that it’s trying to close and that the direction is the opposite.
The
pin 3 of the DIP switch has to be changed).
- 2nd Movement: The door will close 150 mm.
Next 3 movements are to detect the clear opening of the door, the 3rd movement is starting
2 or 3 seconds after finishing the second one.
- 3rd Movement: The door will close completely in slow velocity until the end to detect the
0 position.
- 4th Movement: The door will open slowly counting the pulses from the encoder built into
drive motor until it reach the open mechanical stop. Will detect the final position.
-5th Movement: The door will close after a short delay. From the information obtained the
microprocessor will calculate the acceleration and deceleration ramps and the braking
torque required to give the optimum control of the doors.

Close speed.
The door closing speed can be independently adjusted from 150 mm/s up to 400 mm/s.
53
Open speed.
The door opening speed can be independently adjusted from 200 mm/s up to 700 mm/s.
54
Safety.
This potentiometer is used to set the closing pressure onto an obstacle in the clear opening.
The closing pressure can be set between 60 and 150 Nm.
55
Encoder.
An integral quadrature pulse encoder is connected to this
input. The purpose of the encoder, which is situated inside
the motor, is to inform the control of the exact position and
speed of doors.
Compatibility with Fermator asynchronous motor.
- The VF5 encoder connector is prepared to connect the
high resolution encoder for the synchronous PM motor (5
wires) and the standard encoder from the asynchronous
motor (4 wires).
- The encoder from the asynchronous motor (4 wires) has
to be connected to the 4 pins of the encoder marked like
ASYNC.
56
Motor.
Output to the 3 phase motor varying the voltage and
frequency to control speed and torque.
57
ON / OFF Switch.
Disconnects the unit from the 230 V AC mains supply.
