GCAN (Gantry CAN bus)
The TX machines run with machine CAN bus also second additional gantry CAN bus.
The gantry CAN bus provides the communication for synchronization between the Gantry Control
Units (MGCUs) and the Head Control Units (MHCUs).
GCAN bus participants
MGCU 1/2 (main axis) and MHCUs (head axis).
Fast Drive bus (FDB)
Additionally to the machine and gantry CAN bus system, TX machines use a Fast Drive bus (FDB).
Due to the decentralised drive concept, this CAN system is used for the faster data exchange
between MHCUs and MGCUs, providing extremely fast communication to control the axis, using
transfer rates of 20 Mbit/s (in contrast to the MCAN & GCAN bus with 1 Mbit/s).
The FDB enables you to adapt the data for the drives very flexibly or rather to implement new func-
tions.
The FDB is completely independent of the machine CAN bus.
8.3 MGCU and MHCU
MGCU (Modular Gantry Control Unit):
MGCU is used for controlling of the gantry main axes X & Y; it consists of a control module (CM)
and a power module (PM), comparable to the axis card as control module and the servo card as
power module.
Depending on the MGCU type it can control 2 gantry axis (MGCU2) or 3 gantry axis (MGCU3),
MGCU2 is used on TX machine as controller of the main axes (X/Y axis) of gantry (one MGCU2 for
one gantry).

MHCU (Modular Head Control Unit)

and a power module (PM).

NOTICE
After replacing the BoxPc with new one, the station SW needs to be installed.

Different ports for different monitors, “DisplayPort” (X71) for monitor1 (Power supply side) and
“DVI-I” (X70) for monitor 2.
Before the successful installation of the SW, different displays are shown on each monitor.
8.5 CIN Box
●
In TX-Series machines the, "CAN Interface" CIN [03108598-xx] is used to take over the func-
tion of CAN Card in the previous machines.
●
CIN located in the SMPS and connected to the BoxPC-427D via a LAN cable.
●
For TX machine, the CAN termination on CIN always setting as "OFF".
