5.7 ERROR CODES
Error
Code
Problem or
Symptom
Possible Cause(s) Action/Solution
04 Motor Over
Temperature
Motor thermostat trips due to:
High motor ambient
temperature, and/or
Excessive RMS torque.
Bad encoder cable or
connection. Operate within (not above) the continuous torque rating
for the ambient temperature (40'C maximum).
Lower the ambient temperature to increase motor
cooling.
Check the encoder cable connections. Check the
encoder cable for continuity.
Motor cables shorted. Verify continuity of motor power cable and connector.
Motor winding shorted
internally. Check for short on U,V,W and Gnd windings of the
motor.
Ultra5000 Servo drive
temperature too high. Check for clogged vents or defective fan.
Ensure cooling is not restricted by insufficient space
around the unit.
Operation above continuous
power rating. Verify ambient temperature is not too high (above 60'
C). Operate within the continuous power rating.
05 IPM Fault
Ultra5000 has a bad IPM,
output short circuit, or over
current. Replace Ultra5000.
Low AC line/AC power input. Verify voltage level of the incoming AC power. 09 Bus Under Voltage
100 VAC minimum for safe
Ultra5000 operation. Check AC power source for glitches or line drop (below
90V AC).
Install an uninterruptible power supply (UPS) of the
proper size on your AC input.
Excessive regeneration of
power.
When the motor is driven by an
external mechanical power
source, it may regenerate too
much peak energy through the
Ultra5000's power supply. The
system faults to save itself from
an overload. Lower the deceleration rate.
Excessive AC input voltage. Verify input is below 264V AC.
Output short circuit. Check for shorts.
Motor cabling wires shorted
together. Check for shorts.
10 Bus Over Voltage
Internal motor winding short
circuit. Check for shorts.
Incorrect phasing. Check cables and connections. 11 Illegal Hall State
Bad connections.
The motor encoder encountered
an illegal transition. Replace the motor. Check the Pilot Release settings.
Route the cables away from potential noise sources.
Check the system grounds. 20 Motor Encoder
State Error
Bad encoder. Replace motor.
