eventually create a critical error message and not allow the machine to run until the problem is resolved.
The software will allow the current program to finish before creating the critical error.
5.2.6 Way Covers
The Z ballscrew cover is telescoping in design, so alignment is important to avoid binding, way covers must
be attached in the near fully collapsed state. This is the best way to align the covers to the axis. Do not
move axes around with covers detached but still in the enclosure. The X axis and linear guides on the Z
axis are protected with accordion style covers. The Y axis linear guide rails are mostly unprotected, but are
mounted upside-down underneath the Y-axis casting and thus not directly exposed to contamination.
5.3 Computer Module Diagnostics
The computer module is the main component that controls the system. The computer module is supplied
with 115VAC from the transformer. The module is fitted with 2 fuses (just below the power input).
•
F2: 4A slow blow, protects the power supply inside the computer module.
• F1: 5A slow blow, protects the coolant and lube pump supplies. An indicator lamp shows the
status of this supply.
The computer module consists of 5 main internal components.
1. Motherboard: Runs the operating system, application software and interfaces to the Apps
Board.
2. Applications Board: Machine digital I/O and interfaces to axes and spindle drives
3. IDE Flash: Contains the operating system and application software, plugged into the
motherboard.
4. Power Supply: Provides 5, 12, -12 and 24 volts for the boards inside the computer
module.
5. Fan: To cool the inside components.
The computer module contains a number of LED’s that can be used for troubleshooting. The following
summarizes the LED’s and how they work. See figure 5.3b.
1. Input LED’s – A small, green LED is located next to each input socket. These LED’s turn on when an
input is triggered (connected to ground). The inputs are E-stop, Door, X home, Y home, Z home, air
pressure, tool clamp, tool unclamp, ATC front, ATC back, Unclamp button, Servo On, mill indexer and
lube pump (may be called SPARE 2 on certain modules). There are also spares.
2. Output LED’s – these LED’s come on when the computer commands an output. The light is on for as
long as the output is sent. The outputs are Z axis brake, NC ready, ATC front, ATC back, Tool
Unclamp, status light, door lock and mill indexer. There are also 4 spares. NC ready LED is on when
servos are on. This controls the K1 relay which powers the servo drives.
3. LED’s above the overlay power connector are used to monitor the pressing of the following 5 overlay
buttons: AUX (D32), STOP key (D28), GO key (D29), ON key (D31), OFF key (D30). There is also one
spare LED not used. See figure 5.3d for pin assignments. Please note, early computer modules may
call the AUX the START key.
4. E-stopped 24 VDC Connector - If the E-stop is out there will be 24VDC at this connector. This output is
used to enable the slow start, pneumatic valve (which wil depressurize the pneumatic system when the
machine is E-stopped.
5. Large bank of diagnostic LED’s (RHS of computer module) of which there are 33 + 12. See figure
5.3b. Most of the LEDs are used to monitor the signals for the axis motors. Each axis and the spindle
have 6 LEDs. The A+,A-,B+, and B- are used for encoder counts, as the motor rotates one direction a
particular sequence of LEDs are turned ON and OFF. Note, some of these LEDs are powered by the
monitored subsystem and so may be lit even if the computer module is unpowered. Here is a
summary of the LED’s:
