Electrical Cabinet Components—ISA Platform
Electrical Cabinet Components for machines made prior to 2012 used an ISA Platform,
described in this section.
Operating Temperature
The electronics inside the electrical cabinet are designed to tolerate ambient
temperatures from 0º C (32º F) up to 50º C (122º F). Fans on some of the electronic
assemblies and a heat exchanger on the cabinet door circulate warm air away from
components.The cabinet contains a temperature sensor mounted on the CANbus
controller board in the ISA card rack for machines so equipped.
This sensor is preset to a temperature limit of 55º C (131º F). If the temperature exceeds
the limit, the machine will post an error message for the operator.
Hurco machines that are not equipped with the air conditioning option may be operated
in ambient temperatures to 35º C (95º F), and in relative humidity (non-condensing) up
to 95%.
Control Transformer
The 500VA control transformer converts 230VAC to 200W fpr 115 VAC for the CNC power
supply and 300W for 115 VAC for the field power supply. The AC outlet on the
transformer powers all electrical components.
Power Supply
The DC switching power supply mounted on the ISA card rack converts the 115 VAC input
power to the regulated DC voltages distributed by the DC distribution board. The DC
distribution board supplies regulated DC voltages to all printed circuit board assemblies in
the card cage, console, and control relays.
Card Rack Electronics
The primary CNC-related PC boards that are located in the electrical cabinet are
described below. The ISA Card Rack contains the following microprocessor-controlled
PCBs:
• Main CPU (Single Board Computer and Passive Backplane)
• Dual VGA Board (or Single VGA, depending upon console type)
• Dual Serial Port card for Dual Screen console touchscreen controllers
•CANbus Controller
•CANbus DC I/O Backplane
•CANbus DC I/O Node(s)
•I/O Interface
• SynqNet Motion Controller
• Remote Motion Block(s)
• Floppy Drive Transceiver (if equipped)
