F8078 Speed loop error
Cause
Motor phases (U, V, W) interchanged so that
commutation of motor is incorrect
Incorrect encoder arrangement
Speed loop setting incorrect
Commutation offset incorrect
Motor encoder defective
DOK-INDRV*-GEN-**VRS**-WA01-EN-P
LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
The speed loop monitor is activated if the following conditions occur
simultaneously:
• Parameter S-0-0080, Torque/force command value is at the
torque/force limit.
• S-0-0080, Torque/force command value and actual velocity have
different signs.
• The actual velocity is higher than 20 rpm or 20 mm/min.
• Actual acceleration and control deviation have different signs.
Remedy
Check motor cable connection and correct phase
assignment, if necessary
Correct encoder arrangement (inverting rotational
direction of encoder can possibly resolve problem)
Check speed loop setting according to Application
Manual
Replace motor (in the case of MHD, MKD, MKE motors);
in the case of kit motors, make commutation settings
Replace motor encoder (or motor)

Our machine in Rexroth drive installation total 20 nos machine so facing issue shortly 5 drive folty 8060 erro so how to do
Error 8060 on Bosch Rexroth IndraDrive indicates an overcurrent in the power section. To resolve this issue for five machines, follow these steps for each machine:
1. Check the Load and Connections – Verify that the motor and power connections are correct and not causing excessive current draw.
2. Inspect the Power Section – Look for any visible damage or overheating signs in the power section.
3. Restart the System – Power off the drive, wait for the DC bus to discharge below 50V, and restart.
4. Adjust Parameters if Needed – Ensure that the drive’s current limits and motor settings are correctly configured.
5. Replace Faulty Components – If the issue persists, the power section may be defective and require replacement.
Repeat these steps for all five machines to ensure proper operation.
