Maintaining and Troubleshooting Your Ultra1500 6-7
E036
Drive Overtemperature
Excessive heat exists in the drive
• Verify cooling fan operation (2092-DA4 and
2092-DA5 only).
• Check tuning.
• Reduce acceleration rate.
• Reduce duty cycle (ON/OFF) of commanded
motion.
• Increase time permitted for motion.
• Use larger drive and motor.
E037
AC Line Loss
Poor quality power Increase Ride Through time.
Attempted to enable drive without main
power active
Apply main power before enabling drive.
Phase connection missing Remove power and verify all physical connections.
Fault Delay parameter is set too short Increase the Fault Delay parameter setting.
E053
User Parameter
Initialization Error
Error in parameter memory storage
• Reinitialize parameter.
• Reset drive to factory defaults.
E054
Current Feedback Offset
Defective hardware Replace drive.
E055
User Parameter
Checksum Error
Checksum error
• Confirm and reset parameter.
• Reset drive to factory defaults.
E056
Watchdog Timeout
Excessive system noise Verify wiring and installation methods.
Defective hardware Replace drive.
E057
PWM Hardware Error
Defective hardware Contact A-B.
E058
User Parameter Range
Error
Range of parameter is invalid
• Enter parameter with value(s) within range.
• Reset drive to factory defaults.
E060
Drive Initialization Error
Hardware error Replace drive.
E075
Shunt Overload
Protection
Power at regenerative resistor exceeds
the permitted value
Adjust motion profile to stay within the range of the
regenerative resistor.
Shunt resistor is disconnected or
damaged
• Verify resistor connection.
• Verify resistance of shunt resistor.
E079
Shunt Overcurrent
Protection
Shunt current exceeded allowable
instantaneous value
• Verify shunt is not shorted or damaged.
• Verify load energy is not excessive during
deceleration.
E083
Absolute Encoder Battery
Error
Encoder Backup Battery parameter is set
to installed, but a battery is not installed.
Set Encoder Backup Battery parameter to Not
Installed.
Battery voltage is sensed below 2.7V dc.
• Confirm battery voltage and connection.
• Replace battery.
E084
Absolute Encoder
Overspeed
Battery powered encoder is mechanically
rotated at high speed while drive is
powered down
• Mechanically disengage motor from system.
• Cycle power to drive and reset alarm.
E085
Absolute Encoder
Multi-turn Count Error
Noise in the encoder Cycle power to drive and reset alarm.
Defective encoder Replace motor.
E086
Encoder Single-Turn
Count Error
Noise in the encoder Cycle power to drive and reset alarm.
Defective encoder Replace motor.
