User Parameter Range Error
Range of parameter is invalid. • Enter parameter with a value or values
within range.
• Reset drive to factory defaults.
Drive Initialization Error
Hardware error. Replace the drive.
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.
Shunt Overcurrent
Protection
Shunt current exceeded allowable
instantaneous value. • Verify shunt is not shorted or damaged.
• Verify load energy is not excessive during
deceleration.
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.
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.
Absolute Encoder Multi-turn
Count Error
Electrical noise in the encoder. Cycle power to drive and reset alarm.
Defective encoder. Replace motor.
Drive Set Up
The drive operating mode and motor
selection are incompatible. Change the operating mode and/or the motor
selection, and reset the drive.
Motor Power Cable Open
Motor cable open. Verify power connection between motor and
drive.
Motor Instantaneous
Current Overload
Motion profile requires a peak current for
an excessive time interval. • Verify motor wiring.
• Adjust accel/decel time.
• Confirm motor selection.
Defective current feedback sensing. Verify phase currents.
Motor Mismatch
Dynamic braking current of the selected
motor exceeds twice the drive peak current
rating. Install a different motor.
Encoder Type Mismatch
Motor encoder signals do not match drive
configuration. Verify motor selection.
Defective encoder. Replace motor.
Encoder Communication
Error
Wiring between drive and encoder is faulty
or disconnected, or EMI (noise) disrupts
encoder signals. • Verify encoder wiring.
Special Communication
Error
Communication error between host and
drive (noise). • Verify serial cable.
• Check for noise on serial communication
interface.
Position Command
Frequency Error
Input frequency limit exceeded. • Verify hardware type selected in the drive
matches the physical hardware.
• Change from open collector to line drive.
• Reduce the speed command.
• Apply gearing.
