Detail: Indicates that the current rise rate to the associated channel is indicative of a short circuit condition.
This is a critical fault and will shut down the associated channel.
PFI_OpenFaultOverride
Tip Strip: Determines whether open-circuit faults are indicated
Detail: When set to
OVERRIDE
, the open circuit faults will be ignored and will not be indicated.
OpenCircuitFaults
Tip Strip: Lowside channel open-circuit fault
Detail: An open circuit fault is detected when the current never reaches the requested current level specified
by the lowest current setpoint in Phase 1 or Phase 2 of the PFI 1-4 tab. This is not a critical fault. If an open
circuit fault is indicated, pulses will continue to be delivered to the channel as normal. The open circuit fault
indicator is updated at the end of each delivered command pulse.
