Chapter 2 Faults and Troubleshooting Innovation Series Medium Voltage GP Type - G Drives GEH-6385
No. Name Type Description
153 DSPx Watchdog
Trip
Locke
d
The DSPx Watchdog trip fault occurs when the DSPX EPLD stops seeing a
watchdog toggle bit from the processor. A hard reset occurs and the fault is
declared at initialization.
DSPx Watchdog requires a hard reset to clear.
Possible board failures:
DSPX
154 Reverse rotation Trip The Reverse rotation trip fault occurs when the motor shaft is rotating opposite
to the requested direction.
Related functions:
Speed Control Fault Check
155 Failure to rotate Trip
The Failure to rotate trip fault occurs when speed regulator error grows large
while the speed feedback is small.
Related functions:
Speed Control Fault Check
156 Loss of spd control Alarm
The Loss of spd control trip fault occurs when the speed regulator error is too
large.
Related functions:
Speed Control Fault Check
157 Bic Watchdog Trip The Bic Watchdog trip fault occurs when the BICM stops seeing a watchdog
toggle bit from the DSPX. When the drive is running, BICM monitors a toggle
bit being manipulated by DSPX. If DSPX does not toggle the bit on BICM
within a predefined time interval, the BICM declares a fault and disables the
bridge. This indicates that the processor cannot communicate reliably with the
bridge interface card.
Bic Watchdog requires a hard reset to clear.
Possible configuration faults:
The connected drive is a simulator but Simulate mode act is equal to False.
Set Simulate mode equal to Yes to correct the problem.
Possible board failures:
BICM
DSPX
CABP (backplane)
158 Bic watchdog echo Trip
The Bic watchdog echo trip fault occurs when the DSPX stops seeing the echo
of the watchdog toggle bit that it writes to the BICM. This indicates that the
processor cannot communicate reliably with the bridge interface card.
Primary Causes:
Bent backplane connector pins or poorly seated cards.
Possible board failures:
BICM
DSPX
CABP (backplane)
160 LAN trip request Trip The LAN trip request trip fault occurs when a request for a trip fault is received
from the LAN by assertion of the reference Boolean signal Trip request, lan.
161 LAN alarm request Alarm The LAN alarm request alarm occurs when a request for an alarm is received
from the LAN by assertion of the reference Boolean signal Alarm request, lan.
