REXROTH ECODRIVE03 - E261 Continuous Current Limit Pre-Warning; E263 Velocity Command Value > Limit S-0-0091

ECODRIVE03-SGP-03VRS Description of Diagnostic Messages F… and E… 4-35
DOK-ECODR3-SGP-03VRS**-WA01-EN-P
Remedy:
• In position control, reduce parametrized accel value or speed value so
that the drive can follow the position command value.
• Increase torque limit value, if necessary.
Note: The warning can be deactivated via parameter P-0-0538,
Motor function parameter 1 (bit 11 = 0).
E261 Continuous current limit pre-warning
Digital drives are monitored by a continually operating temperature model.
If the thermal load reaches 100%, the continuous current limit will be
activated shortly thereafter and error E257, Continuous Current Limit
Active, is displayed. Before the torque is reduced, a continuous current
limit early warning is given via a switching threshold, which is determined
by parameter P-0-0127, Overload warning. To deactivate the warning,
enter P-0-0127 = 100% into the parameter.
Cause:
The drive controller was overloaded.
Remedy:
1. Check the drive layout.
2. Reduce acceleration.
3. Increase the switching threshold in parameter P-0-0127,
Overload warning
4. With systems which have been used for longer periods of time,
check to see if drive controller conditions have changed in
regards to:
• Friction
• Movements of the load
• Feed during processing.

E263 Velocity command value > limit S-0-0091
Cause:
S-0-0036, Velocity Command Value is outside the allowed range of
values.
Remedy:
It is limited to S-0-0091, Bipolar velocity limit value.
