Warning Diagnostic Messages (Exxxx)
E8055 Motor overload, current limit active
Cause
Too high acceleration torque/too high acceleration
force demanded
Overload of drive by too high continuous load
Too high process or machining force (e.g. infeed)
Mechanical changes in axis (e.g. friction, load
conditions,...)

Supported by Firmware Variant:
In order to protect the motors against thermal destruction in the case of
peak loads occurring for a very short time, the thermal work load of the
motor is continuously calculated in the controller by means of a motor
temperature model.
If the maximum possible motor current is reduced, due to the current
thermal motor load, compared to the content of S-0-0109, Motor peak
current, the drive generated the warning E8055. As a consequence
thereof the drive can no longer follow the command values preset by a
control unit.
Note:
When the E8055 warning is active, bit 0 (overload warning) is
additionally set in S-0-0012, Class 2 diagnostics.
Remedy
Reduce acceleration by adjusted command value profile
Reduce overload in the case of long machining phases
Reduce process or machining force
Check mechanical system and, if necessary, optimize
load conditions and/or friction conditions

Questions and answers
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.
