8 - POWER SUPPLY
The control unit must be fed by a 230V - 50Hz electric line,
protected by a differential magnetothermal switch complying with
the law provisions in force.
Connect power supply cables to terminals L and N of the control
unit.
Connect the grounding system to one of the two ground
terminals G1 and G2.
9 - OPERATION OF THE MOTOR
The operating speed of the motor can be set with different values,
depending on the various stages of the opening cycle.
Each opening cycle of the gate consists of 5 stages:
1. Acceleration ramp
The speed of the gate gradually increases from the minimum
speed (5Hz) up to the operating one (value set in the parameter
).
VEL
The time required to reach the normal operating speed is
determined by the length of the acceleration ramp (
parameter).
The setting of the value to
then the acceleration will be maximum, the setting of the value
to 6 will result in a long ramp and then the acceleration will be
minimal.
During this phase, the power can be increased up to 30% for
more acceleration through the

2. Regular operating speed
At the end of the acceleration ramp, the gate moves at the speed
set in the parameter
phase.
In this phase, the motor is driven at 100% of its power.
The power supplied to the motor can be decreased by the
parameter .

3. Slowdown
• During the opening phase, the slowdown starts when the
gate reaches the final part of the opening: this final part is
determined by a percentage of the total opening and is set
using the parameter
• During the closing phase, the slowdown starts when the
gate reaches the final part of the closing: this final part is
determined by a percentage of the total closing and is set using
the parameter
RAL.C
When the slowdown starting point is reached, the control unit
gradually decreases the motor speed up to the value set in the
parameter
VEL.R
4. Slowing ramp
Once the limit switch is reached, the speed of the gate is gradually
brought to zero. The duration of the slowing ramp can be set with
the parameter
DECEL
5. Braking
When the motor speed reaches zero, the switch sends a brake
command on the motor phases to ensure that the motor actually
stops.
The intensity of the braking can be set using the parameter
