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
4 - Configure the following:
•
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.

Mounting and Temperature Conditions
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.

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 m
2
minimum for steel and 0.09 m

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
m
m max and
a roughness of 3.2
m
m 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).
Attach the drive using 2
M5 screws (not supplied).
