3 — PROGRAMMABLE PARAMETERS: Vehicle Configuration Parameters
VEHICLE CONFIGURATION: RELAY DRIVER
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Main on Interlock Off / On Determines when the main relay is activated.
Off = Main relay is activated when keyswitch is turned on.
On = Main relay is activated when interlock is on.
Pull-in Voltage 0 – 100 % The relay pull-in voltage parameter allows a high initial voltage when
the relay driver rst turns on, to ensure contactor closure. After 1 second,
the pull-in voltage drops to the holding voltage. The voltage is a percentage
of the nominal voltage.
Holding Voltage
0 – 100 % The relay holding voltage parameter allows a reduced average voltage to
be applied to the relay coil once it has closed. The voltage is a percentage
of the nominal voltage.
This parameter must be set high enough to hold the relay closed under
all shock and vibration conditions the vehicle will be subjected to.
Open Delay
0 – 40 s The open delay can be set to allow the steer relay to remain closed
for a period of time (the open delay) after the interlock is turned off.
The delay is useful for preventing unnecessary cycling of the relay
and for maintaining power to auxiliary functions that may still be used
for a short time after the interlock has turned off.
VEHICLE CONFIGURATION: TRACTION SETTINGS
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Traction Motor Max Speed 0 – 8000 rpm Denes the maximum speed of the traction motor in revolutions
per minute.
Interlock Enable Speed 0 – 100 % Sets the traction motor speed above which the interlock will automatically
be enabled, thus enabling steering. It is a percentage of the Traction
Motor Max Speed
A setting of zero disables this function.
Speed Limit Angle (deg) 0 – 90° The traction controller continuously monitors the Steering Angle Output
(pin J1-12). When this angle is greater than the threshold set by the
Speed Limit Angle (deg) parameter, the traction controller will reduce the
traction motor speed.
Steering Angle Output Interlock
Off / On When a 1313 programmer is connected to the traction controller,
a Communication Lost fault (code 63) is issued on the 1220.
If Steering Angle Output Interlock = On, the Steering Angle Output
(pin J1-12) is xed at 10V to limit the traction motor speed.
If Steering Angle Output Interlock = Off, the Steering Angle Output
(pin J1-12) has its full of 5–9V range according to the actual steered
wheel angle regardless of the status of the Communication Lost fault.
This parameter is useful during commissioning and will be set to On
automatically at every startup.
