Remedy:
For 1. Reduce the ambient temperature, e.g. through cooling of the
control cabinet.
For 2. Remove obstructions or dirt from the heatsink.
For 3. Install the device vertically and clear a large enough area for
proper heatsink ventilation.
For 4. Exchange drive.
For 5. Exchange drive.
F219 Motor overtemp. shutdown
The motor temperature has risen to an unacceptable level.
As soon as the temperature error threshold of 155°C is exceeded, the
drive will immediately be brought to a standstill as set in the error reaction
(P-0-0119, best possible standstill).
It applies:
temperature warning threshold
<
temperature error threshold
See also E251 Motor overtemperature warning.
Cause:
1. The motor is overloaded. The effective torque demanded from the
motor has been above its allowable continuous torque level for too
long.
2. Wire break, short disconnection or circuit in the motor temperature
monitor line
3. Instability in the velocity loop
Remedy:
For 1. Check the installation of the motor. If the system has been in
operation for a long time, check to see if the the operating
conditions have changed. (in regards to pollution, friction, moved
components, etc.)
For 2. Check wires and cables to the motor temperature monitor for wire
breaks, earth short and short circuits.
For 3. Check velocity loop parameters.

F220 Bleeder overload shutdown
1. The regenerated energy from the mechanism of the machine via the
motor has exceeded the capability of the braking resistor (bleeder). By
exceeding the maximum energy of the resistor, the drive will shutdown
according to the set error reaction, thereby protecting the bleeder from
temperature damage.
Cause:
The reflected energy from the machine’s mechanism over the motor is
too great.
