Problem or Symptom

Possible Cause

No ac power or auxiliary logic power.

Verify ac power or auxiliary +5V logic
power is applied to the Ultra3000.

Internal power supply malfunction.

Call your Allen-Bradley representative.

Power (PWR) indicator is ON, but
seven-segment status indicator is OFF.

Note: This only applies to Ultra3000
models 2098-DSD-005, 2098-DSD-010, and

Externally applied +5V auxiliary power
supply voltage is too low.

Verify that the external +5V auxiliary power
supply (as measured at the drive terminals)
reads between 5.10V and 5.25V.

Motor jumps when first enabled

Motor wiring error.

Check motor wiring.

Incorrect motor chosen.

Verify the proper motor is selected.

Digital I/O not working correctly

I/O power supply disconnected.

Verify connections and I/O power source.
