Over Temp Fault
When the amplifier heatsink temperature has reached a level that, if
exceeded, would damage the output transistors:
For 5 LED amplifiers: The Run LED turns off, the OVER TEMP LED
turns on, a Fault Output is generated, and the
amplifier is inhibited.
NOTE: This is a latched condition.
For 1 LED amplifiers: The Green LED turns off, the Red LED
displays 1 flash, a Fault Output is generated,
and the amplifier is inhibited.
NOTE: This is a latched condition.
The following is a list of possible causes:
•
Loss of cooling, or fans are defective, or airflow is blocked.
•
Excessive rise in cooling temperature due to cabinet vents being
blocked or excessive hot air being ingested.
•
Extended operational duty cycle due to mechanical overload of motor
or defective motor.
Over Voltage Fault
When the DC Buss voltage reaches 250VDC:
For 5 LED amplifiers: The Run LED turns off, the OVER VOLTAGE
LED turns on, a Fault Output is generated, and
the amplifier is inhibited.
NOTE: This is a latched condition.
For 1 LED amplifiers: The Green LED turns off, the Red LED
displays 2 flashes, a Fault Output is
generated, and the amplifier is inhibited.
NOTE: This is a latched condition.
The following is a list of possible causes:
•
Main Buss line voltage is too high.
•
Decelerating a large inertial load. When decelerating, a DC motor
acts as a generator. If the inertial load is large, the generated voltage
can pump up the DC-Buss. If this fault occurs, you may need a
Regen Clamp. Consult ANILAM.
Resetting a Fault
The fault latch may be reset by pushing the Reset button, activating the
Reset input J1–12 or by removing power and allowing the filter
capacitor(s) to discharge. Note that the fault latch will not reset unless
the fault has been cleared.
