PG DRIVES TECHNOLOGY AC TRACTION – CONTROLLER SET-UP
1.4 Anti Roll-off (Hill Hold & Restraint) – (Off/Arol)
This sets whether there is a hill-hold and/or restraint function when the vehicle is at rest.
There are three programmable options – 0, 1 and 2.
If set to 0 (Coast), then there is no restraint function and the vehicle is free to coast.
If set to 1 (Hill Hold & Restraint), then the controller will limit the coasting speed of the vehicle. Following neutral braking, the
vehicle will enter and remain in Hill Hold mode for a period set by the parameter, 4.39 Hill Hold Time. During this period, the
vehicle will remain stationary. After this time has elapsed, the vehicle will enter Restraint mode at a speed set by the parameter
4.40 Hill Hold Speed. If the vehicle reaches level ground and the motor is no longer moving, or the handbrake is applied,
Restraint is switched off in order to save battery power. If the motor begins to move again, without Accelerator demand being
applied, then the controller will re-enter Restraint mode until the vehicle either comes to rest or the handbrake is applied.
If set to 2 (Restraint), then the controller will limit the coasting speed of the vehicle. Following neutral braking, the vehicle will enter
Restraint mode, using DC current, for a period set by the parameter, 4.39 Hill Hold Time. After this time has elapsed, the vehicle
will enter Restraint mode at a speed set by the parameter 4.40 Hill Hold Speed. The controller will continue to be restrained until
the motor is no longer moving or the handbrake is applied, just as if set to ‘1’.
1.5 Connector A Pin 5 and 6 – (Spd/Inch)
This sets the function of the input pins 5 and 6 on Connector A.
There are two programmable options – 0 and 1.
If set to 0 (Speed Limit), then the inputs can be used to limit the speed of the vehicle via the parameters, 1.6 Speed Limit 1 and
1.7 Speed Limit 2.
If set to 1 (Inching), then the inputs can be used to “inch” the vehicle. In this case, the function of parameters 1.6 and 1.7 will
become, 1.6 Inching Speed and 1.7 Inching Time.
Both pins are normally closed inputs.
For ease of adjustment, the value of 1.7 Speed Limit 2 / Inching Time should be set to 0Hz before
programming this parameter.
1.6 Connector A Pin 7 – (Spd3/Hbk)
This sets the function of input pin 7 on Connector A.
There are two programmable options – 0 and 1.
If set to 0 (Speed Limit 3), then the input can be used to limit the speed of the vehicle to a level set by the parameter, 1.8 Speed
Limit 3. The limit will apply when a switch connected to pin 7 of Connector A is open.
If set to 1 (Handbrake), then the input can be used to limit the speed of the vehicle to a level set by the parameter, 1.8 Speed
Limit 3. The limit will apply when a switch (normally the Handbrake switch), connected to pin 7 of Connector A is closed. When the
switch is closed, the Sigmagauge will show a ‘parked’ icon.
1.7 Power Steering Trigger – (PsF/FR/S)
This sets the trigger source for the power steer contactor. When the vehicle has stopped driving, a timer sets a delay for the power
steering to remain active. The length of the delay is set by the parameter, 1.19 Power Steering Delay.
There are four programmable options – 0, 1, 2 and 3.
If set to 0 (Footswitch), then the power steer contactor is driven at the instant the Footswitch (Connector A pin 3), is closed.
If set to 1 (Forward/Reverse), then the power steer contactor is driven at the instant either the Forward Switch (Connector A pin 1)
or the Reverse Switch (Connector A pin 2), are closed.
If set to 2 (Seat), then the power steer contactor is driven at the instant the Seat Switch (Connector A pin 4), is closed.
