5.2. Startup Procedure for VTC Software
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.
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 VTC Pattern submenu and set the following: C01 (fmot) (motor rated
frequency); C02 (Speedmax) (desired maximum speed); C03 (Vmot) (motor rated
voltage); C04 (Pnom) (motor rated power); C05 (Imot) (motor rated current); and
C06 (Speednom) (motor rated speed). Also set C07 (resistance of one stator phase
for a star connection or one third of one phase resistance for a delta connection),
C08 (resistance of one rotor phase for a star connection or one third of one phase
resistance for a delta connection) and C09 (inductance of stator leakage of one
phase for star connection or one third of the leakage of one phase for a delta
connection). If values to be set in C07, C08, and C09 are not known, either use
parameter C10 to perform the parameter autotuning (see step 5) or go to step 6.
Press SAVE each time a new parameter value is set.
5) Overload: Set parameter C42 (Limits submenu) depending on the maximum torque that can
be generated.
6) Vectorial control
autotuning: Set C10 to [YES]: close the ENABLE contact (terminal 6) and wait approx. 30 sec.
The inverter will compute the motor parameters. Open terminal 6.
7) Startup: Close terminals 6 (ENABLE) and 7 (START) and send a speed 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.
8) Speed regulator
adjustment: If an overdisplacement occurs when the speed setpoint is reached or if a system
instability is detected (irregular motor operation) adjust the parameters relating to
the speed loop (“Speed loop” submenu; P100 Speed prop. Gain and P101 Speed
integr. time). Set low values for P100 and high values for P101, then increase
P100 until an overdisplacement takes place when the setpoint is reached. Decrease
P100 by approx. 30%, then decrease P101 until an acceptable setpoint response is
reached. Check that the motor runs smoothly at constant speed.
9) Possible failures: If no failure occurred, go to step 10. 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 speed
reference(M01), the supply voltage of the control voltage (M08), the DC link voltage
(M09), the condition of terminals 6,7,8,9,10,11,12, and 13 (M11; if a number
other than 0 appears, this indicates the “activation” of the relevant terminal).
Check to see if these readings match with the measured values.
10) Additional
alterations:
Note that you can change Cxx parameters in the CONFIGURATION menu only
when the inverter is DISABLED.
You can write down any customized parameter in the table on the last pages of the
Programming Manual.
11) 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.
