DOK-ECODR3-SGP-03VRS**-WA01-EN-P
E217 Cooling fan too slow
Owing to dirt particles accumulated at the cooling fan, the minimum
speed of the cooling fan cannot be reached.
Cause:
- Cooling fan is dirty
Remedy:
- Clean or replace cooling fan
E221 Warning Motor temp. surveillance defective
Temperature monitoring checks to see if the measured motor
temperature is within reasonable bounds. If it determines that it is lower
than -10°C, then it is assumed the measuring unit is defective. Warning
E221 Warning Motor temp. surveillance defective will appear for 30
seconds. Afterwards the drive controller will be brought to a standstill
according to the selected error response and message F221 Error Motor
temp. surveillance defective will be generated.
Cause:
1. Motor temperature sensor not connected.
2. Broken cable.
3. Defective sensor.
4. Broken cable in drive controller.
Remedy:
For 1. Connect the sensor to the drive controller and to the motor
(see project planning specifications for the motor).
For 2. Exchange the wiring between the drive controller and the motor.
For 3. Exchange the motor. Use second sensor in the motor if available.
For 4. Exchange the drive controller.

E225 Motor overload
The maximum possible motor current is reduced in order to protect the
motor from being destroyed.
If a current flows in the that is greater than 2.2 times the motor current at
standstill S-0-0111, the maximum possible motor current (S-0-0109,
Motor peak current) is reduced. With 4-fold motor current at standstill,
the reduction starts after 400 ms. With 5-fold current it starts earlier, and
with 3-fold current later. The E225 Motor overload warning is issued
when the motor peak current is reduced by the limitation.
The reduction also has an effect on the P-0-4046, Active permanent
current.
