Steps for Setting Up the Drive
1 - Fit the drive
2 - Connect the following to the drive:
• The line supply, ensuring that it is:
- within the voltage range of the drive
- voltage free
• The motor, ensuring that its coupling corresponds to the supply voltage
• If required, the preset speeds via logic inputs LI3 and LI4
3 - Switch on the drive, but do not give a run command
• The nominal frequency (bFr) of the motor, if it is other than 50 Hz (only appears the first time the drive is
switched on).
• The ACC (Acceleration) and dEC (Deceleration) parameters.
• The LSP (Low speed when the reference is zero) and HSP (High speed when the reference is maximum)
parameters.
• The ItH parameter (Motor thermal protection).
• If required, the preset speeds SP2-SP3-SP4.
5 - Configure the following in the drC menu:
The motor parameters, only if the factory configuration of the drive is not suitable.
6 - Start the drive
Factory configuration
The Altivar 11 is factory-configured for the most common operating conditions:
• Local control via the drive buttons (RUN / STOP, speed reference potentiometer).
• Logic inputs:
- LI1, LI2: not assigned.
- LI3, LI4: 4 preset speeds (speed 1 = speed reference or LSP, speed 2 = 10 Hz,
speed 3 = 25 Hz, speed 4 = 50 Hz).
• Analog input AI1: not active.
• Relay R1: the contact opens in the event of a fault (or drive off)
• DO output: analog output, image of the motor frequency.
If the factory configuration is not suitable, the FUn menu can be used to modify the functions and the I/
O assignments.

Install the unit vertically, at ± 10°.
Do not place it close to heating elements.
Leave sufficient free space to ensure that the air required for cooling purposes can circulate
from the bottom to the top of the unit.
Free space in front of unit: 10 mm minimum.
When IP20 protection is adequate, it is recommended that the protective cover on the top
of the drive is removed, as shown below.
ENGLISH
• From -10°C to 40°C: • d ≥ 50 mm: no special precautions.
• d = 0 (mounted side by side): remove the protective cover on the top of the drive, as
shown below (the degree of protection becomes IP20).
• From 40°C to 50°C: • d ≥ 50 mm: remove the protective cover on the top of the drive, as shown below (the
degree of protection becomes IP20).
• From 50°C to 60°C: • d ≥ 50 mm: remove the protective cover on the top of the drive, as shown below (the
degree of protection becomes IP20), and derate the drive nominal current by 2.2% for
every °C above 50°C.

Mounting the drives on machines
ATV 11P//////A drives can be mounted on (or in) a steel or aluminium machine frame, observing the following
conditions:
Maximum ambient temperature: 40 °C
Vertical mounting at ± 10°
The drive must be fixed at the centre of a support (frame) which is a minimum of 10 mm thick and with a square
cooling area (S) of 0.12 m2 minimum for steel and 0.09 m2 for aluminium, exposed to the open air.
Support area for the drive (min 142 x 72) machined on the frame with a surface smoothness of 100 µm max and
a roughness of 3.2 µm max.
Mill the tapped holes lightly in order to remove any burrs.
Coat the whole support surface of the drive with thermal contact grease (or equivalent).

: function inactive
: Automatic restart, after locking on a fault, if the fault has disappeared
and the other operating conditions permit the restart. The restart is performed
by a series of automatic attempts separated by increasingly long waiting
periods: 1 s, 5 s, 10 s, then 1 min for the following periods. If the restart has
not taken place after 6 min, the procedure is aborted and the drive remains
locked until it is disconnected and then reconnected.
The following faults permit this function: OHF, OLF, ObF, OSF, PHF.
The drive fault relay remains activated if this function is active. The speed

Display of the drive thermal state: 100% corresponds to the nominal thermal state. Above
118%, the drive trips on an OHF fault (drive overheating). It can be reset below 80%.

Faults - Causes - Remedies
Starter does not start, no fault displayed
• Check that the run command input(s) have been actuated in accordance with the chosen control mode.
• When the drive is switched on, at a manual fault reset, or after a stop command, the motor can only be
powered once the "forward" and "reverse" commands have been reset. If they have not been reset, the drive
will display "rdY" or “nSt” but will not start.
Faults displayed
The cause of the fault must be removed before resetting. Faults SOF, OHF, OLF, OSF, ObF, and PHF can be
reset via a logic input if this function has been configured. Faults OHF, OLF, OSF, ObF, and PHF can be reset
via the automatic restart function, if this function has been configured. All faults can be reset by switching the
drive off then on again.
Fault
Remedy
overcurrent
• Ramp too short, check the settings.
• Inertia or load too high, check the size of the motor/drive/load.
• Mechanical locking, check the state of the mechanism.

• Check the cables connecting the drive to the motor, and the insulation of the motor.

• Return to factory settings or call up the backup configuration, if it is valid. See
parameter FCS in the FUn menu.

• Instability, check the motor, gain and stability parameters.
• Driving load too high, add a module and a braking resistor and check the size of the
motor / drive / load.
drive overload
• Check the motor load, the drive ventilation and the environment. Wait for the drive to
cool before restarting.

• Braking too harsh or driving load. Increase the deceleration time, add a braking
resistor if necessary and activate the brA function if it is compatible with the
application.
This protection only operates with the drive on load.
• Check the power connection and the fuses.
• Reset.
• Check the line supply / drive compatibility.
• If there is an unbalanced load, inhibit the fault via IPL = nO (FUn menu).
• Check the voltage and the voltage parameter.
