E2051 Motor overtemp. prewarning

Cause
S-0-0201, Motor warning temperature incorrectly
parameterized
The motor is overloaded. Effective torque demanded
by the motor was above allowed torque for a too long
time
Line interruption, ground fault or short circuit in line
for motor temperature monitoring
Instability in speed control loop
LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
The motor temperature is monitored by a temperature sensor and a
temperature model. As soon as the maximum allowed motor temperature
(S-0-0201, Motor warning temperature) has been reached, the warning
E2051 Motor overtemp. prewarning is output for 30 s. The drive is then
switched off by the error F2019 Motor overtemperature shutdown
being triggered.
Note:
In the case of MHD, MKD, MKE and LSF motors, the motor
overtemperature prewarning cannot be used due to the
temperature sensor characteristic!
For MSK and MLF motors the prewarning function can be
used because an appropriate temperature sensor is used for
these motors.
Remedy
Check and correct parameterization of S-0-0201, Motor
warning temperature by means of motor or
temperature sensor data sheet
Check motor dimensioning and reduce motor load, e.g.
by reduced infeed velocity in the case of metal-cutting
machining. In the case of installations that have been
operated for a long time, check whether drive conditions
have changed (with regard to dirt accumulation, friction,
moved masses etc.).
Check line for motor temperature monitoring for line
interruption, ground fault or short circuit
Check parameterization of speed control loop

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.
