12 Ultra1500 Digital Drives Quick Start
Publication 2092-QS001D-EN-P — July 2005
Continuous Power
Overload
Motion application requires average
drive power in excess of rated capability • Reduce acceleration rates.
• Reduce duty cycle (ON/OFF) of
commanded motion.
• Increase time permitted for motion.
• Use larger drive and motor.
• Check tuning.
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.
• Contact A-B.
Special Communication
Error
Communications error between host and
drive (noise) • Verify serial cable.
• Check for noise on serial 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.
