ENGLISH
START-UP OVERVIEW The following procedure is an overview of the minimum steps necessary for
bringing an ATV31 drive controller into service. Refer to the ATV31
Installation Manual for the mounting, wiring, and bus voltage measurement
steps. Refer to the appropriate sections of this manual for the programming
steps.
1. Mount the drive controller. Refer to the ATV31 Installation Manual.
2. Make the following connections to the drive controller. Refer to the
ATV31 Installation Manual:
— Connect the grounding conductors.
— Connect the line supply. Ensure that it is within the voltage range of
the drive controller.
— Connect the motor. Ensure that its rating corresponds to the drive
controller’s voltage.
3. Power up the drive controller, but do not give a run command.
4. Configure bFr (motor nominal frequency) if it is other than 50 Hz. bFr
appears on the display the first time the drive controller is powered up. It
can be accessed in the drC- menu (page 29) anytime.
5. Configure the parameters in the drC- menu if the factory configuration is
not suitable. Refer to page 12 for the factory settings.
6. Configure the parameters in the I-O-, CtL-, and FUn- menus if the
factory configuration is not suitable. Refer to page 12 for the factory
settings.
7. Configure the following parameters in the SEt- menu (pages 25–29):
— ACC (acceleration) and dEC (deceleration)
— LSP (low speed when the reference is zero) and HSP (high speed
when the reference is at its maximum)
— ItH (motor thermal protection)
8. Remove power from the drive controller and follow the bus voltage
measurement procedure in the ATV31 Installation Manual. Then
connect the control wiring to the logic and analog inputs.
9. Power up the drive controller, then issue a run command via the logic
input (refer to the ATV31 Start-Up Guide).
10. Adjust the speed reference.

ENGLISH
PRELIMINARY RECOMMENDATIONS
Precautions
Before powering up and configuring the drive controller, read and observe
the following precautions.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Before powering up and configuring the drive controller, ensure that the
logic inputs are switched off (State 0) to prevent unintended starting.
• An input assigned to the run command may cause the motor to start
immediately upon exiting the configuration menus.
Failure to follow these instructions will result in death or serious
injury.
WARNING
LOSS OF CONTROL
• The designer of any control scheme must consider the potential failure
modes of control paths and, for certain critical control functions, provide
a means to achieve a safe state during and after a path failure.
• Examples of critical control functions are Emergency Stop and
Overtravel Stop.
• Separate or redundant control paths must be provided for critical control
functions.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.
CAUTION
DAMAGED EQUIPMENT
Do not operate or install any drive controller that appears damaged.
Failure to follow this instruction can result in equipment damage.

ENGLISH
Starting from Line Power If you are starting the drive controller from line power, ensure that parameter
tCt is not set to trn (see page 33), and limit operations of the line contactor
to fewer than one per minute to avoid premature failure of the filter
capacitors and precharge resistors. The recommended method of control
is through inputs LI1 to LI6. The motor thermal state memory returns to zero
when line power is removed from the drive controller.
Power Up after a Manual Fault Reset or
Stop Command
If parameter tCt is at its factory setting (trn), when the drive controller is
powered up after a manual fault reset or a stop command, the forward,
reverse, and DC injection stop commands must be reset for the drive
controller to start. If they are not reset, the drive controller will display nSt
and will not start. If automatic restart is configured (parameter Atr in the FLt-
menu, see page 79) the reset is not necessary.
Test on a Low Power Motor or without a
Motor
With the factory configuration, motor phase loss detection (OPL) is active.
To check the drive controller in a test or maintenance environment without
having to switch to a motor with the same rating as the drive controller,
disable motor phase loss detection and configure the voltage/frequency
ratio (UFt) to L, constant torque (see page 31). The drive controller will not
provide motor thermal protection if the motor current is less than 0.2 times
the nominal drive current.
Using Motors in Parallel When using motors in parallel, configure the voltage/frequency ratio, UFt, to
L (constant torque) and provide an alternate means of thermal protection on
every motor. The drive controller cannot provide adequate motor thermal
protection for each motor.
Operation on an Impedance Grounded
System
When using the drive controller on a system with an isolated or impedance
grounded neutral, use a permanent insulation monitor compatible with non-
linear loads.
ATV31••••••M2
1
and N4 drive controllers feature built-in radio frequency
interference (RFI) filters which have capacitors to ground. These filters can
be disconnected from ground when using the drive controller on an
impedance grounded system to increase the operating life of their
capacitors. Refer to the ATV31 Installation Manual for more information.
Programming Recommendations Refer to “Start-Up Overview” on page 9 for the minimum programming steps
necessary for bringing the drive controller into service.
Use the configuration settings tables beginning on page 91 to prepare and
record the drive configuration before programming the drive controller. It is
always possible to return to the factory settings by setting the FCS
parameter to InI in the drC-, I-O-, CtL-, or FUn- menus. See pages 32, 35,
49, and 77.
When first commissioning an ATV31 drive controller for a 60 Hz system,
perform a factory parameter reset. Be sure to set bFr to 60 Hz.
We recommend using the auto-tuning function to optimize the drive
controller’s accuracy and response time. Auto-tuning measures the stator
resistance of the motor to optimize the control algorithms. See page 31.

ENGLISH
DRIVE THERMAL PROTECTION Thermal protection of the drive controller is achieved with a positive
temperature coefficient (PTC) resistor on the heatsink or power module. In
the event of an overcurrent, the drive controller trips to protect itself against
overloads. Typical tripping points are:
• Motor current is 185% of nominal drive controller current for 2 seconds
• Motor current is 150% of nominal drive controller current for 60 seconds
Ventilation The fan starts when the drive controller is powered up, but stops after
10 seconds if a run command is not received. The fan starts automatically
when the drive controller receives an operating direction and reference. It
stops a few seconds after motor speed is less than 0.2 Hz and injection
braking is completed.

• nSt: Freewheel stop
• FSt: Fast stop
• tUn: Auto-tuning in progress
If a fault is present, the display flashes.
nSt: Freewheel Stop If the display shows the code nSt, one of the following conditions is
indicated:
1. With the factory configuration, when the drive controller is powered up
after a manual fault reset or stop command, the forward, reverse, and
DC injection stop commands must be reset for the drive controller to
start. If they are not reset, the drive controller will display nSt and will not
start. If automatic restart is configured, the reset is not necessary.
2. If the reference channel or the control channel is assigned to Modbus or
CANopen (see page 36), the drive controller will display nSt on power up
and remain stopped until the communication bus sends a command.
3. If a forward or reverse run command is present when the drive controller
is powered up and the drive controller is set for 3-wire control or for
2-wire control with “trn” transition (see page 33) the drive controller will
display nSt and will not run until the run command is cycled and a valid
speed reference is given.

ENGLISH
REMOTE KEYPAD DISPLAY The optional remote keypad display is a local control unit that can be wall-
mounted on the door of an enclosure. It has a cable with connectors for
connection to the drive serial link (refer to the manual supplied with the
display). The remote keypad display has the same display and
programming buttons as the drive controller, with the addition of a switch to
lock access to the menu and three buttons for commanding the drive
controller:
• FWD/REV commands the direction of rotation.
• RUN commands the motor to run.
• STOP/RESET commands the motor to stop or resets a fault. Pressing
the STOP/RESET button once stops the motor; pressing it a second
time stops DC injection braking if it is configured.
In order for the remote keypad display to be active, the tbr parameter in the
COM- menu must remain at the factory setting, 19.2 (19,200 bps, see
page 82).
NOTE: Password protection has priority over the access locking switch. See
page 86.
Placing the access locking switch in the locked position also prevents the
drive settings from being accessed via the drive controller keypad. When
the remote keypad display is disconnected, if the access locking
switch is in the locked position, the drive controller keypad also
remains locked.
Saving and Loading Configurations Up to four complete configurations can be stored in the remote keypad
display and transferred to other drive controllers of the same rating. Four
different operations for the same device can also be stored on the terminal.
See the SCS and FCS parameters in the drC-, I-O-, CtL-, or FUn- menus.
