AC TRACTION – CONTROLLER SET-UP PG DRIVES TECHNOLOGY
1.17 CAN Node Number – (CAN node)
The sets the CAN node number for the controller.
There are sixteen programmable options – 0 to 15.
If set to 0 (Master), then this controller is responsible for the following:
General Indication Field as described in 3.11 Display Status Field.
BDI information for the Sigmagauge.
BDI information to all other controllers (slaves), attached to the CANbus.
Checking the state of all slaves when a shared line contactor is used.
Controlling the line contactor when a shared line contactor is used.
Device, fault icon and pulsing information to the Sigmagauge.
If set from 1 to 15, the controller will be a slave.
In multiple controller systems, it is essential that all CAN nodes have a unique number. A slave uses the BDI from the master so
disregards it’s own BDI and associated settings 1.31, 1.32 & 1.33. However, the BDI cut-out levels, 1.34 and BDI speed, 1.35, still
apply. In this way the BDI is equal to all devices on the CANbus, while each controller can set up it’s own cut-out and speed
levels. All slaves also send out their device, fault code icon and pulsing information to the Sigmagauge.
In a non-CANbus system, the controller(s) should have this parameter set to 0. This is particularly important if the BDI is used. As
detailed above, the BDI will not work when set up as a slave controller.
To set the CAN node number in a controller, it must be disconnected from the CANbus.
1.18 Shared Line Contactor – (ShareLC)
This sets whether the controller is able to share a line contactor with another controller(s) in a CANbus connected network.
The Master Controller regularly checks all slaves that share the line contactor, in addition to controlling the line contactor itself. If
the Master Controller or one of the slaves reports a hard error, it will open the line contactor. Likewise the Master Controller will also
open the line contactor if one of the slave controllers fails to respond to it. Whenever the Master Controller opens the line
contactor, it sends a warning message to each of the slaves that are sharing it to go into a ‘safe’ mode.
If parameters are set up incorrectly, the Master Controller will issue an error.
There are two programmable options – 0 and 1.
If set to 0 (No Sharing), then each controller must have a separate line contactor.
If set to 1 (Sharing), then the controllers with a CAN node number in sequence, starting from 1 on the CANbus network will be able
to use the line contactor from the Master Controller. If this value is selected, then the parameter, 3.19 Last Sharing Node, must
also be set on the Master Controller. Setting this parameter on a slave has no effect.
1.19 Last Sharing Node – (LstNode)
Only the Master Controller uses this setting. If there are multiple controllers sharing a line contactor, connected via the CANbus,
then this should be set to the highest node number of the sharing controllers.
For example, if there are four controllers connected and they have node numbers of 0, 1, 2 and 3, then this parameter should
be set to 3.
