NOTE: Please also refer to the Programming Manual.

When the drive is powered up, the power components and some of the control
components are connected to the line supply. It is extremely dangerous to touch
them. The drive cover must be kept closed.

In general, the drive power supply must be disconnected before any operation on
either the electrical or mechanical parts of the installation or machine.
After the ALTIVAR has been switched off and the display has disappeared
completely, wait for 10 minutes before working on the equipment. This is the time
required for the capacitors to discharge.
The motor can be stopped during operation by inhibiting start commands or the
speed reference while the drive remains powered up. If personnel safety requires
prevention of sudden restarts, this electronic locking system is not sufficient: fit
a cut-off on the power circuit..

The drive is fitted with safety devices which, in the event of a fault, can shut down
the drive and consequently the motor. The motor itself may be stopped by a
mechanical blockage. Finally, voltage variations, especially line supply failures,
can also cause shutdowns.
If the cause of the shutdown disappears, there is a risk of restarting which may
endanger certain machines or installations, especially those which must
conform to safety regulations.

In this case the user must take precautions against the possibility of restarts, in
particular by using a low speed detector to cut off power to the drive if the motor
performs an unprogrammed shutdown.

The drive must be installed and set up in accordance with both international and
national standards. Bringing the device into conformity is the responsibility of
the systems integrator who must observe the EMC directive among others within
the European Union.
The specifications contained in this document must be applied in order to
comply with the essential requirements of the EMC directive.

The Altivar 31 must be considered as a component: it is neither a machine nor a
device ready for use in accordance with European directives (machinery
directive and electromagnetic compatibility directive). It is the responsibility of
the end user to ensure that the machine meets these standards.

The drive must not be used as a safety device for machines posing a potential
risk of material damage or personal injury (lifting equipment, for example). In
such applications, overspeed checks and checks to ensure that the trajectory
remains under constant control must be made by separate devices which are
independent of the drive.

The products and equipment described in this document may be changed or
modified at any time, either from a technical point of view or in the way they are
operated. Their description can in no way be considered contractual.

(1)These power ratings and currents are for a maximum ambient temperature of 50°C and a switching frequency of 4 kHz in continuous

operation.The switching frequency is adjustable from 2 to 16 kHz.
Above 4 kHz, the drive will reduce the switching frequency in the event of excessive temperature rise. The temperature rise is controlled
by a PTC probe in the power module. Nonetheless, the nominal drive current should be derated if operation above 4 kHz needs to be
continuous.

Removing the protective cover

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, we recommend that the protective cover on the top of the drive be removed,
as shown below.
