Parameter 324 [Fault Status 2]
This parameter indicates the presence of certain drive anomolies that
caused the drive to fault (stop). These are the same events shown in
parameter 321 [Exception Event 2]. These bits are latched until they
are reset by setting bit 19 [Clear Fault] of parameter 152 [Applied
LogicCmd]. After turning the Clear Fault bit on, the drive may be
re-started after turning the command bits off and then back on again.
If the fault conditions still exist, the identifying bit in this parameter
will immediately be set again. The fault conditions reported in this
register result in turning off the drive.
Bit 12 Motor Stall A motor stall has lasted longer than the time specified by
parameter 373 [Motor Stall Time]. This has faulted the drive
module. Refer to parameter 374 [Moter Stall Cnfg].
Bit 18 DSP Mem Err Flash memory does not match the SRAM memory.
Bit 19 DSP Err The drive has failed to complete DSP (VPL) interrupt tasks in
the allotted time.
