7.3 Set-up procedure for AC traction inverter
This section describes the basic set-up procedure for ACE0/COMBIAC0 to be
carried out using the Zapi Console.
When the key switch is closed, if no alarms or errors are present, the Console
display shows the standard Zapi opening line.
For the setting of your truck, use the procedure below.
If you need to reply the same settings on different controllers, use the SAVE and
RESTORE sequence. Remember to re-cycle the key switch if you want to make
active any change to the configuration.
- In ADJUSTMENTS, set BATTERY VOLTAGE according to the nominal
battery voltage (see paragraph 8.2.3).
- Check the wiring and that all commands are functioning. Use the
TESTER function to have a real-time feedback about their state.
- Perform the accelerator acquisition using the PROGRAM VACC
procedure (see paragraph 9.1).
- Set the maximum current for traction and braking in MAX. CURRENT
TRA and MAX. CURRENT BRK (see paragraph 8.2.1).
- Set the motor-related parameters. It is suggested to discuss them with
Zapi technicians.
- Set the parameter SET MOT.TEMPERAT according to the type of motor
thermal sensor adopted.
- Set the acceleration delay (parameters ACCEL MODULATION and
ACCEL DELAY). Test the behavior in both directions.
- Set the FREQUENCY CREEP starting from 0.3 Hz. The machine should
just move when the drive request is active. Increase the level
accordingly.
- Set speed reduction as required by your specifications (see parameter
HB ON / SR OFF in list SET OPTIONS).
- Set the other performance-related parameters such as RELEASE
BRAKING, INVERSION BRAKING, DECELERATION BRAKING, PEDAL
BRAKING, SPEED LIMIT BRAKING, MAX SPEED FORW, MAX SPEED
BACK.
- Set the parameters related to the behavior on a slope (STOP ON RAMP
and AUXILIARY TIME parameters).
- Test the truck in all operative conditions (with and without load, on flat
and on ramp, etc.).
7.3.1 Sin/cos-sensor case
Sin/Cos sensors have a sinusoidal output voltage, with variable amplitude and
offset, and normally sin/cos wave has an arbitrary shift with respect to the
magnetic-field zero position. Offset, amplitude and angle must be set before
starting a PM for the first time.
Preliminary settings are the same as described above. Plus, an automatic
acquisition procedure embedded in the inverter software is to be activated only
once at commissioning.
Before starting the procedure, be sure that the motor is free to spin, with a
minimum load on the shaft.
- In OPTIONS, select ABS SENS. ACQUIRE.
- Select NO at the request of saving data (otherwise the main coil will be
opened).
- The message ACQUIRING ABS indicates that the acquisition procedure
is ready to start.
