In the case of installations that have been operated for a long time, check
whether the drive conditions have changed with regard to:
•
friction
•
moved masses.
See also the functional description: "Current Limit").
E259 Command velocity limit active
In the position control and velocity control operating modes, the effective
velocity command value is limited to the value in parameter
S-0-0091,
Bipolar velocity limit value . The warning is given if the resulting velocity
command value reaches this limit.
Cause:
Parameter S-0-0091, Bipolar velocity limit value was set too low.
Remedy:
In normal operating conditions, set parameter S-0-0091, Bipolar velocity
limit value to a value 10% greater than the NC maximum velocity.
See also the functional description: "Limiting to bipolar velocity limit
value".
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.
