Bit Fault Name Fault Description
Bit 0 Abs OverSpd Motor speed has exceed the value in Parameter 335 [Abs
OverSpd Lim].
Bit 1 SpdRef Decel The drive has failed to achieve a zero speed condition.
Bit 6 Ctrl EE Mem Not Used
Bit 7 SLink HW Not Used
Bit 8 SLink Comm A SynchLink communication failure has occurred. These
faults are enumerated in parameter 1229 [SL Error Status].
Bit 10 Mtr OL Trip A Mtr OL Trip exception event has alarmed the drive module.
