ECODRIVE Drive Controller DKC02.1

DOK-ECODRV-SSE-03VRS**-WAR1-EN-P • 12.96 Warning Diagnostic Messages 3-1

3 Warning Diagnostic Messages

E249 Positioning vel. (S-0-0259) greater S-0-0091

Cause:

For "drive-internal interpolation" mode, a velocity is specified in the

parameter S-0-0259, Positioning velocity that is used for approaching

the specified target position.

The message E249 is generated if that velocity is higher than the

permissible maximum value S-0-0091, Bipolar Velocity Limit Value.

The message bit 4 in S-0-0013, Class 3 Diagnostics is set at the same

time.

Remedial action:

Reduce S-0-0259, Positioning velocity

E250 Drive Overtemperature Warning

The temperature of the heat sinks in the drive controller has reached the

maximum permissible value. The drive follows the command value

specification for a period of 30 seconds. Thus, the axis can be stopped

via the controller in a process-related manner (e.g. terminating

machining, exiting interference zone, etc.). After these 30 seconds, the

drive performs the reaction that has been specified in the parameter P-0-

0119, Deceleration as best as possible.

Cause:

1. Failure of the inbuilt fan

2. Failure of the cabinet air conditioning

3. Incorrect switchgear cabinet dimensioning with respect to heat

dissipation

Remedial action:

Ref. 1. Replace the drive controller in the event of a fan failure.

Ref. 2 Establish the function of the cabinet air conditioning system.

Ref. 3 Check switchgear cabinet dimensioning.

E251 Motor Overtemperature Warning

The motor temperature has risen beyond the maximum permissible

value. The drive follows the command value specification for a period of

30 seconds. Thus, the axis can be stopped via the controller in a

process-related manner (e.g. terminating machining, exiting interference

zone, etc.). After these 30 seconds, the drive performs the reaction that

has been specified in the parameter P-0-0119, Deceleration as best as

possible.

Cause:

Motor overload.

The effective torque requested from the motor has exceeded the

permissible standstill continuous torque value for too long a time.
