PG DRIVES TECHNOLOGY AC TRACTION – ADJUSTMENTS
Together with 1.29 Reverse Threshold, this parameter forms a ‘deadband’ in which the wig-wag assumes a neutral position.
The adjustable range is 0V to 5V in 0.1V steps.
1.29 Reverse Threshold – (RevTH)
The operation of this parameter is dependant on the setting of 3.14 Analogue Inputs Set-up, in the Controller Set-up Menu. If that
parameter is set to 2 (Wig-wag), then this value sets the voltage on pin 9 of Connector A from which reverse drive commences.
Together with 1.28 Forward Threshold, this parameter forms a ‘deadband’ in which the wig-wag assumes a neutral position.
The adjustable range is 0V to 5V in 0.1V steps.
1.30 Max. Vehicle Speed – (VmaxSpd)
This sets the maximum value that is indicated on the Sigmagauge LCD when the vehicle is driving at maximum speed. To
calibrate this value to the output from the encoder, set the parameter, 4.2 Motor to Vehicle Speed Ratio, in the Motor Set-up
menu.
The adjustable range is 0kph to 100kph in 1kph steps.
Setting the parameter to 0kph means that there will be no indication of speed shown on the Sigmagauge LCD.
1.31 BDI Reset Level – (BDIreset)
This sets the voltage at which the BDI will reset to show a 100% charged battery on the Sigmagauge. This setting only has an
effect at power-up.
The adjustable range is 18V to 125% of the nominal operating voltage of the controller in 0.1V steps.
1.32 BDI Empty Level – (BDIempty)
This sets the 0% charge level for the BDI. Whenever the battery voltage is equal to or less than 1.18 Battery Voltage, the BDI on the
Sigmagauge will start to decrease.
The adjustable range is 12V to 125% of the nominal operating voltage of the controller in 0.1V steps.
1.33 BDI Warning Level –
(BDIwarn)
This sets the level of battery charge at which the BDI warning icon on the Sigmagauge will start to flash. The value is set as a
percentage of battery charge. 100% battery charge corresponds to the voltage set by the parameter, 1.31 BDI Reset Level and
0% battery charge corresponds to the voltage set by the parameter, 1.32 BDI Empty Level.
The adjustable range is 0% to 99% in 1% steps.
1.34 BDI Cut-out Level –
(BDIcut)
This sets the level of battery charge at which the speed of the vehicle will be limited to a value set by the parameter, 1.35 BDI
Speed Limit. The cut-out value is set as a percentage of battery charge. 100% battery charge corresponds to the voltage set by
the parameter, 1.31 BDI Reset Level and 0% battery charge corresponds to a level set by the parameter, 1.32 BDI Empty Level.
The adjustable range is 0% to 99% in 1% steps.
1.35 BDI Speed Limit –
(BDIspeed)
This sets the maximum speed of the vehicle if the BDI level is below the value set by the parameter, 1.34 BDI Cut Out Level.
The adjustable range is 0Hz to 255Hz in 1Hz steps.
