8.1.1 Sequence for Ac traction Inverter setting
This section of the manual describes the basic AC-0 set-up procedure using the
hand-set.
When the "Key Switch" is closed, if no alarms or errors are present, the Console
Display will be showing the Standard Zapi Opening Display (Home Display).
For the setting of your truck, use the procedure below.
If you need to reply the same setting on different controller, use the Save and
Restore sequence as described in the 10.1 and 10.2 paragraphs. Remember to
re-cycle the Key Switch if you make any changes to the chopper’s configuration.
Step1 Fill your setting with the Options you need (see “Set options”
submenu in paragraph 9.4.1).
Step2 Select the Battery Voltage. See SET BATTERY TYPE in
“Adjustments” submenu.
Step3 Check the correct installation of all wires. Use the Console’s
TESTER function to assist.
Step4 Perform the accelerator signal acquisition procedure using the
Console “PROGRAM VACC”. Procedure is detailed on paragraph
10.3.
Step5 Set the “MAXIMUM CURRENT” Current, using the table on Chapter
9.5.1 (setting table of the “PARAMETER CHANGE” functions).
Step6 Set the ACCELERATION DELAY requirements for the machine.
Test the parameters in both directions.
Step7 Set the FREQUENCY CREEP level starting from 0.6 Hz. The
machine should just move when the accelerator microswitch is
closed. Increase the Level accordingly.
Step8 Set the Speed Reductions as required. Use the parameters of the
“cutback speed” family in the PARAMETER CHANGE menu to
specify the reduced maximum truck speed as a percentage of the
MAX SPEED FWD and MAX SPEED REV (see 9.5.1.9-10-11-12).
Step9 RELEASE BRAKING. Operate the machine at full speed. Release
the accelerator pedal. Adjust the level to your requirement. If the
machine is a forklift, check the performance with and without load.
Step10 INVERSION BRAKING. Operate the machine at 25% full speed.
While travelling invert the Direction Switch. Set the suited Level of
Inversion Braking. When satisfactory, operate the machine at Full
Speed and repeat. If the machine is a Forklift, repeat the tests and
make adjustments with and without load. The unlade full speed
condition should be the most representative condition.
Step11 PEDAL BRAKING (If used). Operate the machine at full Speed.
Release the accelerator pedal and press the Pedal Brake. Set
braking level to your requirements.
Step12 Set the parameter MAX SPEED FORW.
Step13 Set the parameter MAX SPEED BACK (Reverse).
Step14 Test the truck on the maximum ramp specification at full load.
Step14 Make the choice for the truck behaviour on a slope (see chapter
10.4). If the "Stop on ramp" option is ON, set the desired value of
"auxiliary time" parameter.
Step15 Set SET TEMPERATURE, setting the motor thermal sensor type
used.
