Steps for Setting Up the Drive
1 - Fit the drive
2 - Connect the following to the drive:
3 - Switch on the drive, but do not give a run command
4 - Configure the following:
• The nominal frequency (bFr) of the motor, if it is other than 50 Hz for the E range or other than 60 Hz for the
U range (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).
• The preset speeds SP2-SP3-SP4.
• The speed reference if it is other than 0 - 5 V (0 -10V or 0 -20mA or 4 -20mA).
ENGLISH
FRANÇAIS
• The line supply, ensuring that it is:
- within the voltage range of the drive
- off
• The motor, ensuring that its coupling corresponds to the supply voltage
• The control via the logic inputs
• The speed reference via the logic or analog inputs
5 - Configure the following in the drC menu:
The motor parameters, only if the factory configuration of the drive is not suitable.
The Altivar 11 is factory-configured for the most common operating conditions:
• Logic inputs:
- LI1, LI2 (2 directions of operation): 2-wire control on transition, LI1 = forward, LI2 = reverse.
- 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: speed reference (0 + 5 V).
• 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.

When the drive is running, the value displayed is that of one of the monitoring parameters. The default value
which is displayed is the motor reference (parameter FrH).
While the value of the required new monitoring parameter is being displayed, the "ENT" key must be pressed
a second time to confirm the change of monitoring parameter and to store it. From then on the value of this
parameter will be displayed during operation (even after the drive has been switched off).
If the new choice is not confirmed by pressing the "ENT" key for a second time, the drive will return to the
previous parameter after it has been switched off.

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.

• 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.

• Instability, check the motor, gain and stability parameters.
• Driving load too high, add a braking module and 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.
