560 Fault Variables
Clear this fault with a Reset Fault block, set to Reset 1394.
Important: Do not use an Equation block to clear this fault. The Reset
Fault block not only resets this variable to zero, it also resets
the Drive OK Relay inside the 1394 system module. This
relay must be reset before the System Bus can be reapplied.
In the Tag Explorer, select both Axis System Variables and the desired
physical axis, then select Axis_Drive_over_temp_fault_1394 in the Tag
Window.
Axis It Fault 1394
An axis it fault occurs when an enabled 1394 axis module detects that the
motor current integrated over time (It) exceeds the capability of the power
block.
Axis_it_fault_1394 is a logical (Boolean) variable, with a value or:
• 1 (true) if an enabled 1394 axis module detects that the motor current
integrated over time (It) exceeds the capability of the power block,
and
• 0 (false) if not.
When Axis_it_fault_1394 = 1, Axis_module_hard_fault_1394 = 1, and
Drive_hard_fault_1394 = 1.
Clearing this fault clears Drive_hard_fault_1394.
Clear this fault with a Reset Fault block, set to Reset 1394.
!
ATTENTION: A hard fault is a serious condition! Be
certain to correct the underlying cause of this fault,
before clearing the fault and reactivating the drive.
