Ipim Module Fault Diagnosis - Allen-Bradley Kinetix 6000M User Manual

IPIM Module Fault Diagnosis

Condition Potential Cause
No rotation The IDM unit connections are loose or
open.
Foreign matter is lodged in the IDM unit.
The IDM unit load is excessive.
The bearings are worn.
The IDM unit brake is engaged (if
supplied).
The IDM unit is not connect to the load.
IDM unit overheating The duty cycle is excessive.
The rotor is partially demagnetized
causing excessive IDM unit current.
Abnormal noise IDM unit tuning limits are set too high.
Loose parts are present in the IDM unit.
Through bolts or coupling is loose.
The bearings are worn.
Mechanical resonance.
When a fault condition is detected, it is added to a fault log, opens the power rail
SYSOK and reports the fault to the IAM module. This causes a loss of bus power
to all modules on the Bulletin 2094 power rail and associated IDM units. If an
IPIM module fault is detected, the fault will be displayed on the IPIM module.
In addition, the IPIM module will display IDM unit faults.
The IAM module generates a fault whenever an IPIM module fault occurs,
regardless of the state of the contactor. IDM unit faults are not displayed by the
IAM module.
Issuing a fault reset command to the IAM module will also send a fault reset
command to the IPIM module.
The IPIM module maintains a log of the last 50 faults reported by the IPIM
module or any of the connected IDM units. Each fault contains the source of the
fault (IDM unit number or IPIM module), the fault number, and a timestamp
with the cumulative power-on time of the IPIM module.

Troubleshooting the Kinetix 6000M System
Possible Solution
Check IDM unit wiring and connections.
Remove foreign matter.
Verify the servo system sizing.
Return the IDM unit for repair.
• Check brake wiring and function.
• Return the IDM unit for repair.
Check coupling.
Change the command profile to reduce accel/
decel or increase time.
Return the IDM unit for repair.
Run Tune in RSLogix 5000 software.
• Remove the loose parts.
• Return IDM unit for repair.
• Replace IDM unit.
Tighten bolts.
Return IDM unit for repair.
Notch filter may be required (refer to Axis
Properties dialog box, Output tab in
RSLogix 5000 software).
