STARTUP
PROCEDURES
The startup procedures described below relate to commands sent via terminal board (factory setting). For the
configuration of the terminal board, see the Control Terminals section.
DANGER
Before changing the equipment connections, shut off the inverter and wait at least
5 minutes to allow for the discharge of the capacitors in the DC-link.
DANGER
At startup, if the connected motor rotates in the wrong direction, send a low
frequency reference and check to see if the direction of rotation is correct.
CAUTION
When an alarm message is displayed, find the cause responsible for the alarm
trip before restarting the equipment.
5.1.
Startup Procedure for IFD Software
1) Connection:
Follow the instructions stated in the CAUTION STATEMENTS and WIRING sections.
2) Power on:
Link to terminal 6 (ENABLE) is to be open when the inverter is started.
3) Parameter alteration: Use the PROG,

and SAVE keys to access the other parameters. See the
"Submenu Tree" in the Programming Manual.
4) Motor parameters:
Access the V/f Pattern submenu and set the following: C05 (Imot) (motor rated
current); C06 (fmot1) (motor rated frequency); C07 (fomax1) (maximum output
frequency desired) and C09 (Vmot1) (motor rated voltage). Press SAVE each time a
new parameter value is set. For loads producing a quadratic pattern of the torque
with respect to rpm (turbo pumps, fans, etc..), set C11 (preboost) to 0%. Press SAVE
to store the new parameter value.
5) Overload:
Set parameters C41/C43/C45 in the Limits submenu based on the max. current
desired.
6) Startup:
Close terminals 6 (ENABLE) and 7 (START) and send a frequency reference: the
RUN LED and REF LED will come on and the motor will start. Make sure the motor
is rotating in the right direction. If not, operate on terminal 12 (CW/CCW) or open
terminals 6 and 7. Shut off the inverter, wait a few minutes and reverse two of the
motor phases.
7) Possible failures:
If no failure occurred, go to step 8. Otherwise, check the inverter connections
paying particular attention to supply voltages, DC link and input reference. Also
check if alarm messages are displayed. In the Measure submenu, check the
reference frequency (M01), the supply voltage to the control section (M05), the DC
link voltage (M06), and the condition of terminals 6, 7, 8, 9, 10, 11, 12, and 13
(M08; a number other than 0 indicates the "activation" of the relevant terminal).
Check to see if these readings match with the measured values.
8) Additional alterations: Note that you can change Cxx parameters in the CONFIGURATION menu only
when the inverter is DISABLED or STOPPED.
You can write down any customized parameter in the table on the last pages of the
Programming Manual.
9) Reset:
If an alarm trips, find the cause responsible for the alarm and reset the equipment.
Enable terminal 8 (RESET) for some time, or press the RESET key.
