What to do if Danfoss Servo Drives system fuse blows?
If the system fuse blows, the circuit breaker trips, or the drive protection trips immediately, it could be due to a short circuit or incorrect control loop parameters. Check the wiring. For further assistance, contact Danfoss.
What causes Danfoss Servo Drives to make a screaming noise?
If the drive is screaming, it may be due to incorrect calibration, a faulty current measurement, or incorrect control loop parameters. Check the parameter settings and contact Danfoss.
What causes Danfoss Servo Drives to make (unusual) running noises?
Unusual running noises in the servo drive can stem from a defective bearing, defects on connected mechanics, or incorrect control loop parameters. Check the shaft, look for loose mechanical components on the attached mechanics, and check the parameter settings.
What causes vibration in Danfoss Servo Drives?
Vibration in the servo drive can be caused by a defective bearing or incorrect control loop parameters. Check the shaft and the parameter settings.
Why Danfoss Servo Drives have wrong motor rotation direction?
If the motor rotation direction is wrong, it is likely due to a parameter error. Check the parameter settings and change the rotation direction if appropriate.
Why Danfoss Servo Drives run normally, but does not generate the expected torque?
If the drive runs normally but does not generate the expected torque, it could be due to a defective drive or a parameter error. Check the parameter settings and contact Danfoss.
What to do if Danfoss Servo Drives LEDs do not light up?
If the LEDs do not light up, the cause is likely that there is no power supply. Check the power supply.
Why Danfoss Servo Drive does not run or starts up slowly?
If the servo drive does not run or only starts up slowly or with difficulty, it could be due to bearing wear, incorrect parameter settings, incorrect control loop parameters, or incorrect torque settings. Check the bearings and shaft, and verify the parameter settings.
What to do if Danfoss Servo Drives speed drops sharply under load?
If the drive speed drops sharply under load, it may be running at the current limit or with incorrect parameters. Check the application and the parameter settings.
Why do Danfoss Servo Drives stop suddenly and not restart?
If the drive stops suddenly and does not restart, this may be because of no drive communication or the servo drive is in error mode. Check the fieldbus connection and the status indicators (LEDs) on the servo drive.
