Warnings
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 IEC 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.

Using the traverse control programming manual
This document should be used in conjunction with the Altivar 31 programming manual.
It describes functions and parameters that are additional or different to the Altivar 31.
Differences from the Altivar 31

• Different factory configuration (see page 4
• Compatibility of the different functions (see page 5
• Assignments of the different analog/logic output and relays (see page 8
• Diagrams of the different reference channel (see pages 9
• Application functions menu FUn-:
- Addition of the Traverse control sub-menu: tCO- (see page 17
- Different PI Regulator sub-menu: PI- (see page 20

Factory configuration
Factory settings
Factory settings which are specific to the AltivarpppT are underlined.
The Altivar 31 is factory-set for the most common operating conditions:
• Display: Drive ready (rdY) with motor stopped, and motor frequency with motor running
• Motor frequency (bFr): 50 Hz
• Constant torque application (UFt = L)
• Suppression of the speed loop filter (SrF = YES)
• Normal stop mode on deceleration ramp (Stt = rMP).
• Stop mode in the event of a fault: Freewheel
• Linear ramps (ACC, dEC): 3 seconds
• Low speed (LSP): 0 Hz
• High speed (HSP): 50 Hz
• Motor thermal current (ItH) = Nominal motor current (value depending on drive rating)
• Standstill injection braking current (SdC1) = 0.7 x nominal drive current, for 0.5 seconds
• Automatic adaptation of the deceleration ramp in the event of overvoltage on braking
• No automatic restarting after a fault
• Switching frequency 4 kHz
• Logic inputs:
- LI1: Forward, 2-wire transition detection control, non-reversing, inactive on the ATV31
LI2: Inactive (not assigned)
-
- LI3: Traverse control command
- LI4: Inactive (not assigned)
- LI5 - LI6: Inactive (not assigned)
• Analog inputs:
- AI1: Speed reference 0-10 V, inactive on ATV 31
- AI2: Summed speed reference input 0±10 V
- AI3: 4-20 mA inactive (not assigned)
• Relay R1: The contact opens in the event of a fault (or drive off)
• Relay R2: Inactive (not assigned)
• Analog output AOC: 0-20 mA inactive (not assigned)
.
ppppppAT drives (not assigned)
ppppppAT.
ATV 31ppppppAT range
When they leave the factory, ATV 31ppppppAT drives are supplied with local control activated: the RUN, STOP buttons and the drive
potentiometer are active. Both logic input LI1 and analog input AI1 are inactive (not assigned).
If the above values are compatible with the application, the drive can be used without changing the settings.

Function compatibility
Incompatible functions
The following functions will be inaccessible or deactivated in the cases described below:
Automatic restart
This is only possible for 2-wire level detection control (tCC = 2C and tCt = LEL or PFO).
Flying restart
This is only possible for 2-wire level detection control (tCC = 2C and tCt = LEL or PFO).
This function is locked if the automatic DC injection on stopping is configured as Continuous (AdC = Ct).
Reverse
On the ATV31pppAT range only, this function is locked if local control is active (tCC = LOC).
Function compatibility table
The choice of application functions may be limited by the number of I/O and by the fact that some functions are incompatible with one
another. Functions which are not listed in this table are fully compatible.
If there is an incompatibility between functions, the first function configured will prevent the remainder being configured.
To configure a function, first check that functions which are incompatible with it are unassigned, especially those which are
assigned in the factory setting.
