ECODRIVE DKC01.1/DKC11.1 Drive Controllers
2-14 Description of Diagnostic Letters F... and E... DOK-ECODRV-ASE-02VRS**-WAR1-EN-P • 07.96
E257 Continuous Current Limiting Active
Description:
The drive controller sets the peak current available for 400ms. Thereafter,
the continuous current limit becomes active and dynamically limits the
peak current to the continuous current.
Cause:
More continuous torque was required than was available.
Remedy:
1. Check the drive installation.
• 2. Check the installation of the motor. For systems which have
been in use for a long time, check to see if the drive conditions
have changed (in regards to pollution, friction, components which
have been moved, etc).
E258 Selected Process Block is not Programmed
Cause:
A positioning block was selected for which there is no set target position,
positioning velocity, etc.
Remedy:
Select another positioning block or enter the required data.
E259 Command Velocity Limit Active
Description:
The velocity command value is limited to the value set in the "S-0-0091,
Bipolar Velocity Limit" parameter when in the position and velocity
control operating modes. This warning is given if the value in the "S-0-
0036, Velocity Command Value" parameter reaches this limit.
Cause:
"S-0-0091, Bipolar Velocity Limit" parameter was set too low.
Remedy:
In normal operation, set the "S-0-0091, Bipolar Velocity Limit"
parameter to a value 10% higher than the NC operation velocity.
