DSP Error 1394

A DSP Error 1394 (Runtime_fault = 32) indicates that an internal
hardware error has occurred within the DSP in the system module.
Consequently, handshaking between the i960 and the DSP stops during
firmware code execution.

A system or axis module hard fault
occurred.

To check for a hard fault:
1. Select General System Variables in

the Tag Explorer, and scroll to
Drive_Hard_Fault_1394 in the Tag
Window.

2. Check for the presence of an

Axis_module_hard_fault_ 1394 or a
System_module_hard_fault_ 1394.

3. If either fault exists, find the

underlying axis or system hard fault.

4. Locate and remedy the cause of the

fault.

5. Clear the underlying fault with a

Reset Fault block set to Reset 1394.

6. Press the Reset button on the

controller.

A hardware problem exists with a
system, axis, or DIM module.

Isolate the malfunctioning module, as
follows:
1. all axis and DIM modules.
2. Plug the terminator into the system

module. If the system module is OK
(system LED flashing red/green), go
to step 3. If not (system LED solid
red) go to step 4.

3. Plug in each axis and DIM module

one at a time, re-attaching the
terminator after each module is
added. See which module causes
the system to fail (system LED solid
red).

Note: If no module fails, combine the
axis modules in different order until one
fails.
4. Return the malfunctioning module to

the manufacturer for repair.
