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

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.
