Remedy:
Press S1 button on the drive controller, and all the parameters will be
erased and restored with the factory preset default values
WARNING

F218 Amplifier overtemperature shutdown
The temperature of the amplifier’s heatsink is monitored. If the heatsink is
too hot, the drive will power down in order to protect against damage.
Cause:
1. Ambient temperature is too high. The specified performance data are
valid up to an ambient temperature of 45 °C.
2. The amplifier’s heatsink is dirty.
3. Air flow is prevented by other assembly parts or the control cabinet
assembly.
4. Blower defective.
5. E219: Sensor defective appears prior to shutdown of unit
For Remedy:
1. Reduce the ambient temperature, e.g. through cooling of the control
cabinet.
2. Remove obstructions or dirt from the heatsink.
3. Install the device vertically and clear a large enough area for proper
heatsink ventilation.
4. Exchange drive.
5. Exchange drive.
F219 Motor overtemperature shutdown
If the motor temperature exceeds the value in S-0-0204, Motor
shutdown temperature , the drive will generate this error message. The
value in S-0-0204 is fixed at 150 °C for MDD-,MKD- and MKE motors.
The appropriate value must be entered from the motor's technical
specifications for all other types of motors.
For motors of series: 2AD, 1MB, LAF, LAR, and MBW, the current motor
temperature can be called up with parameter
S-0-0383, Motor
temperature .
Cause:
1. The motor became overloaded. The effective torque demand on
the motor was above its permissible continuous torque level for
too long.
2. Short circuit or disconnection in the connection to
motor temperature monitoring.
3. Instability in the velocity control loop.
