The Allen-Bradley 1398 Ultra servo drive product line is a series of single-axis digital and positioning servo drives. It comprises 2 sub-series which are the Ultra 100 and Ultra 200 series, and both of these can be managed through the Windows-based Ultra Master software. The 1398 Ultra 100 and 200 drives can be set up as indexing drives, stepper drives, velocity servo drives, or master encoder followers. Ultra 100 drives can be remotely programmed through the DeviceNet network option. The 1398 Ultra 100 and 200 drives are available in 7 power ranges and they are compatible with 4 brushless servo motor families. The 1398 Ultra 100 drives support single-phase 115 to 230 Volts AC input voltage, they include integrated logic power supplies, they can drive AC brushless motors, they support control algorithms for velocity loop bandwidth and velocity and position loops, they include a 14-bit analog-to-digital converter, and support multiple analog and digital I/Os. One RS-232/RS-485 port is included as a standard feature.
The Allen-Bradley 1398 Ultra 100 drives are available in power ratings ranging from 0.5 kilowatts to 2 kilowatts and they require a –5 to 50 degrees Celsius operating temperature range. The 1398 Ultra 200 drives support 115 to 230 Volts AC input voltage. The 75 Amps drives support both single and 3-phase input while the 150 Amps drives support only 3-phase input. Features available on the 1398 Ultra 200 drives include an internal resistive shunt, a built-in power supply, an advanced multiprocessor design, a 16-bit analog to digital converter, short circuit protection, flash memory for field upgrades, and multiple analog and digital command interfaces. The 1398 Ultra 200 drives are available in power ratings ranging from 1 to 15 kilowatts.

Two indicators on the front panel continuously display the drive status:
A table of problems, potential causes, and appropriate responses to resolve the problem is located below.
| Problem | Error Code | Possible Causes | Response |
| Status display not lit. |
No AC power Blown power fuse(s) |
Ensure power (115/230VAC single phase or 230 VAC three phase) is applied to the drive. Check for open circuits in the AC line fuses |
|
| DC BUS LED not lit. |
No Bus power Blown power fuse(s) |
Make sure AC power is connected to the drive Check for open circuit breakers in the AC line |
|
| Motor jumps when first activated |
Motor encoder wiring error Incorrect motor selected in personality module |
Inspect motor encoder wiring. Review Figure 6.36 on page 30 to verify connection of encoder power sense signals. Choose the proper motor in ULTRA Master |
|
| Digital I/O not working correctly | 24V power supply disconnected | Ensure P5/P6 jumper settings are correct | |
| +24V Fuse Blown | E01 | F1 Blown |
The fuse on the I/O isolated +24VDC power supply has tripped. Check and replace fuse F1 if necessary. Check for short circuits on I/O or +24VDC output |
| +5V Fuse Blown | E02 | F2 Blown |
The fuse on the encoder power output for the +5VDC power supply has tripped. Check and replace fuse F2 if necessary. Check for short circuits on Encoder output signals or +5V output. Check that J4 pin9 or J5 pin9 is not connected to any external circuit. |
| Encoder Fuse Blown | E03 |
F3 Blown Bad encoder |
Check for short circuits on the motor Encoder signals and cable wiring. Check and replace fuse F3 if necessary. |
| Motor over temperature | E04 |
Motor TS+ (J2-19) and TS- (J2-20) pins open Motor thermostat will trip due to: High motor ambient temperature and/or Excessive RMS torque |
Verify TS+ (J2-19) and TS- (J2-20) connections for continuity. Lower ambient temperature. Operate inside (not above) the continuous torque rating for the ambient temperature (40° Celsius maximum). |
| IPM Fault | E05 |
Motor cables shorted Motor winding internally shorted Drive temperature running too high Operation above continuous power rating Output short circuit or overcurrent |
Ensure continuity of motor's power cable and connector. Check for short circuit on R, S, T, and Gnd windings. Check for a clogged or deffective fan. Ensure that cooling is not restricted by insufficient space around the unit. Ensure that ambient temperature is not too high (above 60° Celsius). Operate drive within the continuous power rating. Driver has a bad IPM, replace drive. |
| Channel IM line | E06 |
Bad connection Bad encoder |
Ensure continuity of the encoder cable. Ensure continuity of the IM+ and IM- wiring signals. Replace the motor or Eencoder. |
| Channel BM line | E07 |
Bad connection Bad encoder |
Ensure continuity of the encoder cable. Ensure continuity of the BM+ and BM- wiring signals. Replace the motor or encoder. |
| Channel AM line | E08 |
Bad connection Bad encoder |
Ensure continuity of the encoder cable. Ensure continuity of the AM+ and AM- wiring signals. Replace the motor or encoder. |
| Bus under voltage | E09 | Low AC line/AC input (100 V AC minimum for safe drive operation) |
Check voltage level of the incoming AC power. Check main VAC power source for glitches or drop (below 90 VAC). Install an uninterruptible power supply (UPS) on your VAC input. |
| Bus over voltage | E10 |
Excessive regeneration of power. When the drive is operated by an external mechanical power source, it may regenerate too much peak energy through the drive's power supply. The system will fault to save itself from an overload. Excessive AC voltage input Output short circuit Motor cabling wires shorted together Internal motor winding short circuit |
Change the deceleration or motion settings and/or reduce the reflected intertia of your mechanical system, or use a larger system (motor and drive). Ensure input is below 264 VAC. Inspect for short circuits Inspect for short circuits Inspect for short circuits |

Increase Average Current parameter to a more permissive setting. Correct the under voltage condition or intermittent AC power, or install a larger size transformer. |
| Motor over speed | E18 |
OVERSPEED parameter in the drive may be set too low for the application Motor commanded to run above overspeed setting Motor phasing is incorrect Motor encoder phasing is incorrect |
