PG DRIVES TECHNOLOGY AC TRACTION – ADJUSTMENTS
1.15 Neutral Braking End Delay – (NBrkEnd)
This setting is normally associated with a Walkie type vehicle fitted with an electromechanical brake connected to pin 13 on
Connector A. This setting allows a time to hold the vehicle at zero speed, i.e. hill hold, when the Neutral Braking Ramp time, 1.13
or Footbrake Ramp time, 1.14, have passed. It is usually used in conjunction with the parameter 1.20 Electric Brake Delay to
operate the electromechanical brake.
The adjustable range is 0.1s to 10.0s in 0.1s steps.
1.16 Sweep Speed – (SweepSpd)
This sets the maximum speed at which an instant direction change is possible. The purpose of the parameter is to minimise any
delays as the vehicle is ‘sweeping’ through zero speed during a direction changeover.
The adjustable range is 0Hz to 5.0Hz in steps of 0.0625Hz. The programmed value relates to the frequency output of the
controller, i.e. the motor’s stator speed.
1.17 Maximum Current – (MaxCurr)
This sets the maximum current limit during driving and braking.
The adjustable range is 10Arms to the maximum rating of the controller in 10Arms steps.
1.18 Battery Voltage – (BattV)
This should be set to the nominal battery voltage of the system.
Whenever the battery voltage is equal to or less than this value, the BDI on the Sigmagauge will start to decrease.
The adjustable range is 24V to the maximum rating of the controller in 2V steps.
1.19 Power Steering Delay – (PStrDly)
This sets the period that the Power Steer Contactor input, pin 14 on Connector A, will remain active after the trigger source has
been removed. The trigger source is as set by the parameter, 3.7 Power Steering Trigger, in the Controller Set-up menu.
The adjustable range is 0s to 50s in 0.1s steps.
1.20 Electric Brake Delay – (EBrkDly)
This setting is normally associated with a Walkie type vehicle fitted with an electromechanical brake connected to pin 13 on
Connector A. The value, e.g. 0.2s, sets the delay between detecting the vehicle is at standstill and the electric brake being
applied.
There is also a fixed period of 0.1s that sets the delay from when pulsing starts, to the electric brake being released. This helps
prevent roll back on a Walkie truck when starting drive on a gradient.
The adjustable range is 0s to 50s in 0.1s steps.
1.21 Accelerator 0% Voltage – (AccMin)
This sets the voltage on the Accelerator input that will correspond to zero speed*.
The adjustable range is 0V to 5V in 0.1V steps.
The Accelerator input can be configured via the parameter, 3.14 Analogue Inputs Set-up, in the Controller Set-up menu.
1.22 Accelerator 100% Voltage – (AccMax)
This sets the voltage on the Accelerator input that will correspond to maximum speed*.
The adjustable range is 0V to 5V in 0.1V steps.
