556 Fault Variables
System_over_temp_fault_1394
System_phase_loss_fault_1394
System_smrt_pwr_i_limit_fault_1394
System_smrt_pwr_pre-charge_fault_1394
System_smrt_pwr_shunt_timeout_fault_1394
To clear this fault, you must clear the underlying fault with a Reset Fault
block, set to Reset 1394.
Important:Do not use an Equation block to clear the underlying 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 program execution
can be resumed.
In the Tag Explorer select General System Variables, then select
System_module_hard_fault_1394 in the Tag Window.
Axis Power Fault 1394
Axis_power_fault_1394 is a logical (Boolean) variable with a value of:
1 (true) if an enabled 1394 axis module detects any of the following
conditions:
Instantaneous 300% over-current condition
Power block short circuit
Power block over-temperature
Loss of base drive to power block
0 (false) if not.
When Axis_power_fault_1394 = 1, Axis_module_hard_fault_1394 = 1,
and Drive_hard_fault_1394 = 1.
Clearing this fault clears Drive_hard_fault_1394.
