Faults 2-95
Resetting or Clearing a Fault
A latched fault condition can be cleared by the following:
1. An off to on transition on a digital input configured for fault reset or
stop/reset.
2. Setting [Fault Clear] to “1.”
3. A DPI peripheral (several ways).
4. Performing a reset to factory defaults via parameter write.
5. Cycling power to the drive such that the control board goes through a
power-up sequence.
Resetting faults will clear the faulted status indication. If any fault condition
still exists, the fault will relatch and another entry made in the fault queue.
Clearing the Fault Queue
Performing a fault reset does not clear the fault queue. Clearing the fault
queue is a separate action.
Fault Configuration
The drive can be configured such that some fault conditions do not trip the
drive. Configurable faults include those that are user inputs.
[Fault Config 1] is a bit-mapped 16 bit word enabling or disabling certain
fault conditions (see below). Disabling a fault removes the effect of the fault
condition and makes the event unknown to the user. If the bit is on, the fault
is enabled. If the bit is off, the fault is not enabled.
Power Up Marker
Copy of factory “drive under power” timer at the last power-up of the drive.
Used to provide relevance of Fault 'n' Time values with respect to the last
power-up of the drive.
This value will rollover to 0 after the drive has been powered on for more
than the hours shown in the Range field (approximately 47.667 years).
