E250 Drive overtemp. prewarning
The temperature of the heatsink in the drive controller has reached the
maximum permissible temperature. The drive controller follows the
command value input for a period of 30 seconds. This makes it possible
to bring the axis to a standstill with the control system while keeping true
to the process (for example, close the operation, leave the collision area,
etc.).
After 30 seconds, the response set in parameter P-0-0119, Best
possible deceleration will be performed by the drive controller.
Cause:
1. Failure of the drive’s internal blower.
2. Failure of the control cabinet’s climate control.
3. Incorrect control cabinet sizing in regards to
heat dissipation.
Remedy:
For 1. If the blower fails, exchange the drive controller.
For 2. Install climate control feature in the cabinet.
For 3. Check the sizing of the control cabinet.

E251 Motor overtemp. prewarning
As soon as the temperature warning threshold (145°C) is exceeded,
the warning E251 is output, and the drive keeps on following the
command value.
This state can last for a long time without powering down. Only when the
temperature error threshold is exceeded, an immediate powering down
will take place.
See also F219 Motor Overtemperature Shutdown.
Cause:
The motor is overloaded. The effective torque required from the motor
was above the allowable standstill continuous torque for too long.
Remedy:
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, moving components, etc).
