140 Troubleshooting the Kinetix 2000 Drive System
SM Status Indicators
Each of the shunt module LED indicators provide specific troubleshooting
information.
General Shunt Module Troubleshooting
Flashing Green
Bus power is present, axis disabled.
No faults or failures.
Normal when:
• 24V is not applied to Hardware Enable Input (IOD/AF-43).
• MSO instruction is not commanded in RSLogix 5000 software.
Off
Bus power not present.
• Normal when bus power is not applied.
• Fault exists, refer to Seven-segment LED Indicator Error Codes section beginning
on page 134.
Bus power is present in follower IAM.
• Follower IAM is not configured as CommonBus Follow in RSLogix 5000
software.
• After dc bus voltage is applied, a 2.5 second delay before the LED indicator
begins flashing green is normal operation to provide common bus leader time to
complete pre-charge.
Bus Status LED
Indicator
Status Condition
Module Status Under These Conditions
SM
Fault is latched Until fault condition is corrected and cleared.
Fault is cleared
• Using RSLogix MASR, MAFR, MGSR commands or the HIM (red
stop button).
• Only after the dc bus is discharged (SM Bus Status LED indicator is
flashing).
• Drive must be configured with 2093-ASP06 or Bulletin 1336
external shunt resistor.
IAM/AM
Disabled (for dc bus
regulation)
• When the 2093-ASP06 shunt module is used on a 230V system.
• When a 230V system is configured with a Bulletin 1336 external
shunt resistor.
• When configured in Common Bus Follower mode.
Enabled to discharge the dc
bus
Drive (IAM or leader IAM) three-phase power is removed.
Disabled from discharging
the dc bus
When configured in common bus follower mode.
IMPORTANT
Under some fault conditions, two reset commands may be required to
clear drive and SM faults.
