Corrective action
Check cable between AZL and PC. A null modem
adapter must be used on the 9 pin connector if the cable
does not have this internally. A USB to serial adapter is
OK to use when connecting the AZL to a laptop.
1) If fault occurs sporadically: Improve EMC.
2) If fault occurs constantly: Replace AZL5...
1) If fault occurs sporadically: Improve EMC.
2) If fault occurs constantly: Replace LMV5
1) Possibly interference on the line to the speed sensor,
check cable routing, use shielded cable.
2) If fault occurs sporadically: Improve EMC.
3) If fault occurs constantly: Replace VSD Module.
1) This indicates that a fault has been relayed to the
LMV5 from the VSD via the VSD alarm input terminal.
This indicates a fault in the VSD, not the LMV5. Thus,
check the VSD error codes and take action based on
those codes.
2) Check VSD settings (ramps, motor settings),
increase ramp time on VSD and basic unit, if necessary.
3) Check Motor and VSD for proper sizing.
