Initialization And Adjustment - Fagor ACSD series Original Instructions Manual

Initialization and adjustment

The system can only be initialized and adjusted using the CAN field
bus (communication interface included in the ACSD drive). This
process is carried out from the master device (CNC).
NOTE. Remember that the serial line can only be used to down-
load the software to the drive.
WARNING. To update the software version of the ACSD drive, the
CNC must be disconnected. If this condition is not met, the user
must reset it with a <SHIFT+RESET> once the software has been
loaded.
Initially, bear in mind the elements that make up each drive in order
to configure the communication with the master device. These ele-
ments are:
TERMINAL RESISTOR. Terminating resistor
Before starting up the system, the last drive connected to the bus
will be the farthest away from the master device and must be the
only whose terminating resistor is activated (ON). The rest of the
drives must have it turned OFF.
See figure of section - CAN field bus connection -
NODE SELECT. Node selector
Rotary selector that together with the SPEED SELECT switch is used
to determine the node number assigned to the drive in the CAN bus.
The node number must be selected before starting up the drive,
otherwise it will only be valid after restarting and resetting the drive
again. The protocol does not accept the "0" node; therefore, selecting
it implies going into the "bus speed selection" sequence.
