Current Overload
Motor Mismatch
Possible Cause
Range of parameter is invalid
Hardware error
Power at regenerative resistor exceeds
the permitted value
Shunt resistor is disconnected or
damaged
Shunt current exceeded allowable
instantaneous value
Encoder Backup Battery parameter is set
to installed, but a battery is not installed.
Battery voltage is sensed below 2.7V dc.
Battery powered encoder is
mechanically rotated at high speed
while drive is powered down
Noise in the encoder
Defective encoder
Noise in the encoder
Defective encoder
The drive operating mode and motor
selection are incompatible.
Motor cable open
Motion profile requires a peak current
for an excessive time interval
Defective current feedback sensing
Dynamic braking current of the selected
motor exceeds twice the drive peak
current rating
Ultra1500 Digital Drives Quick Start
Action/Solution
• Enter parameter with value(s) within
range.
• Reset drive to factory defaults.
Replace drive.
Adjust motion profile to stay within the range
of the regenerative resistor.
• Verify resistor connection.
• Verify resistance of shunt resistor.
• Verify shunt is not shorted or damaged.
• Verify load energy is not excessive during
deceleration.
Set Encoder Backup Battery parameter to Not
Installed.
• Confirm battery voltage and connection.
• Replace battery.
• Mechanically disengage motor from
system.
• Cycle power to drive and reset alarm.
Cycle power to drive and reset alarm.
Replace motor.
Cycle power to drive and reset alarm.
Replace motor.
Change the operating mode and/or the motor
selection, and reset the drive.
Verify power connection between motor and
drive.
• Verify motor wiring.
• Adjust accel/decel time.
• Confirm motor selection.
Verify phase currents.
Install a different motor.
