F218 Amplifier overtemp. 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
apply 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 is defective
Remedy:
For 1. Reduce the ambient temperature, e.g. through cooling of the
control cabinet.
For 2. Clean heatsink.
For 3. Install the device vertically and clear a large enough area for
proper heatsink ventilation.
For 4. Replace 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 in accordance with the
type of error response selected (A119, Best possible deceleration).
The following applies:
temperature warning threshold
<
temperature error threshold
See also E251 Motor overtemperature prewarning.
Cause:
1. The motor is overloaded. The effective torque demanded by the
motor has been above its allowable continuous torque level for too
long.
2. Wire break, ground fault or short circuit in the motor temperature
monitoring line
3. Instability in the velocity loop
Remedy:
For 1. Check the motor rating. If the system has been in operation for a
long time, check to see if the operating conditions have changed.
(with regard to contamination, friction, moved components, etc.)
For 2. Check the motor temperature monitoring line for wire breaks,
ground faults and short circuits.
For 3. Check velocity loop parameter settings.
